Devin Westbrook/Summons

As a user of Ethereal Body Subordination Magic, Devin has several — in not thousands of spirits under his command, all through the use of his signature weapon; due to him having a unique keenness towards the afterlife after the tragic events of his events, he's able to deal with the strain of utilizing various spirits at a time — especially for a young man of his age. Each one of his spirits are known to be extremely powerful in their own right. It's unknown how he's able to conquer them all, but he notes that some of them came to him, feeling a strong attachment to the world they lived in before their passing; they see him as a way to continue living on before deciding when they feel the need to cross over to the other side. He also notes that he's able to collect spirits through the use of his Praesepe Magic, one that also deals in the manipulation of souls; however, he only uses this method when he deems necessary, opting for the first method — seeing it as more... mundane.

It's noted that out of all the spirits in his collection, there are thirteen that he uses mainly for combat purposes — used as somewhat of a last resort, as their skills are enough to decimate any opponent they go up against; it's because of them that many see Devin as unbeatable by normal means. Each one is incredibly powerful in their own right, taking much effort to defeat them. Due to their shared theme of black, they're dubbed as the "Dark Necrospirits" (, Dāku Nekurosupiritto; lit. "Demonic Warlords of Utter Annihilation Stained Black"), by Devin himself — thinking that the name is accurate; he's noted to cherish each one of them greatly, taking "proper care" of them in his own way. They're the only spirits that Devin hasn't collected personally, already being part of the blade. He also notes that it's ironically fitting that there's thirteen of them in total — a number associated with bad luck and superstition; this is due to the reputations that they gained respectively during their life, which caused them to be despised by those who knew of them, and their unfortunate demise sometime after. Interestingly enough, all of them are users of Darkness Magic like Devin — being their signature magic as a whole, having some of level of skill in the art, while having their individual magics under their respective control — further alluding to the theme of black.

Thousand Unknown Realities, Abyssion
Thousand Unknown Realities, Abyssion (千不明実·アビシオン, Senfumeijitsu, Abishion): Considered to be the first spirit in the series to be sealed into Intetsukijin, it was a powerful Etherious who had an incredible ability of conjuring advanced illusions through its curse; due it the curse's unlimited potentials, the demon eventually gained its moniker by the people of his time — his infamy growing as a result. With such a thing under its command, it was able to wreak havoc on the continent for many generations. It was eventually slain through the efforts of Intetsukijin's first wielder, who sadly died shortly after from his injuries; his personality was initially violent, but it slowly grew more obedient and silent as it spent time in its new prison, subjugated by the various energies within the blade.

According to Devin, he's considered to be one of the most obedient spirits to-date and the one he's able to easily communicate with; in fact, Devin once stated that he favors him above all others due to his subservient attitude and little resistance he puts up.

Magics & Abilities: Due to his skills in casting Illusions and the like, he's considered to be good for diversionary tactics and escape methods; however, his true potential is seen when employed with other summons — being able to cover for them while making it harder for his enemy to get a good read on their movements. While not the most powerful of the series, he's good at other skills such as hand-to-hand combat, making him useful when in close-range.

Undead Vindicator, Holmusif
Undead Vindicator, Holmusif (不死裁·ホルミューシフ, Fushisai, Horumyūshifu): Originally the spirit of a fair judge who held the concepts of justice and virtue to heart, he was known to meed out punishment to criminals and aided in giving solace to many victims; while he gained the love of the general public, he earned the ire of many criminals and dark mages. It was such that a large group decided to put aside their differences and attacked him together, killing him in succession; after mutilating his body and scattering it to various parts of the globe — his head was displayed in town to set an example to those who disobeyed them, striking fear and dread in the hearts of the innocent.

Having a strong desire to live on and take his vengeance on those who've killed him, his spirit took on what is now seen; after taking his fulfilling his purpose — killing those who murdered him, he wandered the earth for a long time — passing judgment on those who've committed grave sins against humanity. His legend became well-known for many generations, striking dread into the hearts of evil beings. It's also because of such legend that he got his current epithet; while the details are unknown, he was eventually sealed in Intetsukijin by one its previous wielders — becoming the second spirit in the series to be trapped within its cold steel confines.

Due to their reasons coinciding with each other, Devin commonly works with Holmusif — seeking the blood of those who have wronged them and others.

Magics & Abilities: True to his status as a Vindicator, the magic and skills in his possession are good for subduing an opponent; he mainly uses his chains for combat, but also employs other magic that either makes him hard to hit or nullifies enemy offenses with little ease. He's noted to be fast on his feet and is able to keep up with even the most swift-footed of opponents. Since he also acts as a sensor, it's possible for him to find his enemy's location or hid his presence and that of his allies altogether.

Incantation: "Open, gate of the Spiteful Judge." (開け、執念深い裁判官の扉, Hirake, Shūnenbūkai Saibankan no Tobira)

Diabolous Serpent of Infinity, Zegramelek
Diabolous Serpent of Infinity, Zegramelek (暴悪無類蛇の無限大·ゼグラマーリック, Bouakumuruija no Mugendai, Zeguramāryukku): A mastodonic black Wyvern of overwhelming and unfathomable power — outclassing even those who are supposed to be greater than his general species, he's one of the few of his kind to earn the distinct title of "Wyvern King" (従龍神, Juryūjin) — signalling his rule over his kind; living for over many millennia, he's known to have mastered various types of magic aside from his unique magic that's noted to be similar to the ones used by Dragons, making him unrivaled both in knowledge and in power. He gained many titles as time passed, making him even more feared than thought possible; one which dealt with his atrocious personality and his somewhat tyrannical rule over his kind, "Tyrant Black Wyvern God" (冥暗覇従龍神, Meian Haōjuryūjin). It's said that he was rivals with Laharash — a Dragon with an incredible degree of power under her command, constantly challenging her to battle in order to prove his superiority; whenever the two battled, it always ended in his loss — even when the two held back for personal reasons, as his race's physiology was naturally much weaker than that of a Dragons, something he couldn't overcome. As one who's able to subjugate all things, he's known for viewing anything less powerful than he as an "insect" — his own kind included; this was especially the case for Humans and Demons, two species he saw as food for his and Dragon kind.

During the Dragon Civil War, he was naturally recognized as the leader of the faction that opposed co-existing with humans — finding the utter thought to be disgusting, despite belonging to a species that was lesser to a Dragon in terms of power; he utterly caused havoc to those who opposed him, displaying sheer awesome power at every turn. He eventually fell when he faced Acnologia — the Human-turned-Dragon, the latter's power outclassing his own due to him bathing in the blood of both his fellow Dragon Slayers and Dragons alike, evidentially stripping him of his title and status. As an ambitious individual hellbent on seeking vengeance on the new Black Dragon King, his spirit lived on — taking on a more corporeal form, seen as somewhat of an extension of his incredible abilities; he continued wreaking havoc across the land for many years, spreading as much pain and suffering as possible. His ambitions were put to rest however by one of the previous wielders of Intetsukijin, using the Ethereal Body Subordination Magic to seal him into the sword's cold confines — albeit at the cost of his life. This made him the third spirit in the series to have been sealed; despite this, he's as restless as ever, having the strong desire for destruction and chaos — staying true to his name and nature.

According to Devin, he's considered to be the most unreasonable of all of his black-themed brethren, thus employs him in the most drastic of situations — much to the Wyvern's chagrin.

Magics & Abilities: Typically referred to as the one of, if not the most powerful summon in the entire series — barring the spirit of Intetsukijin himself, his vast array of magics and skills, combined with his destructive power — which is noted to be enough to mow down armies of opponents at once and overpower any spell aimed at its being, makes him a match for any and all opponents that dare challenge him; Devin commonly boasts that whenever he's summoned, silver-haired man becomes nigh unbeatable.

Incantation: "Open, gate of the Apocalyptic Dragon." (開け、黙示竜の扉, Hirake, Mokushiryū no Tobira)

Sorcerer of the Underworld, Decarigorn
Sorcerer of the Underworld, Decarigorn (魔道士の黄泉·デカりゴルノ, Madoushi no Yomi, Dekarigoruno): A Black Mage who's lived for hundreds upon hundreds of years and a Necromancer of incredible prowess, he's mastered and subsequentially many branches of the Black Arts — surpassing even the infamous Black Wizard himself, a well-known user known throughout the annals of history, in terms of number and type, something only one other person was able to do. Using his incredulous knowledge, he was said to have conjured an army of undead creatures under his command — using their power to subjugate most of the countries in Ishgar, thus staying true to his epithet given to him by those at-large. He singlehandedly caused the death of millions of people, the extinction of over a thousand species — plants and animals alike, and fell over a hundred cities and towns — most of which were under the jurisdiction of the Magic Council at the time. For many years, Ishgar knew the very concept of fear and powerlessness, as no one was able to oppose his tyrannical conquest.

It was until a millennia later that he was opposed a faction of powerful and legendary mages hailing from various dimensions, who've heard of his tyranny against the continent; through their combined effort — backed by the support of the people, that he was eventually slain and his armies destroyed. This officially put an end to one of the darkest periods in Ishgar's history, the heroes now worshiped as gods for many years to come and their incredible deeds forever recorded in history. Sometime later, the user of Intetsukijin at such a turbulent time sealed his soul into the blade — preventing him from passing on and put him through an eternity of suffering under the power of another. This makes him the fourth spirit in the series to be sealed.

Devin noted that, despite his reputation, he has an amiable and reasonable personality — which may be due to him getting accustomed to his new "home" over the centuries after his demise. Due to his incredible knowledge, Devin tends to rely on him for advice on various subjects; despite his erratic impulses of destruction, this spirit has much self-control, something Devin commented on various times.

Magics & Abilities: A mage of incredible prowess and a fellow master of the Black Arts, Decarigorn is considered to be an excellent battle summon, noted to be an all-rounder when it comes to magic; he's often employed with other summons, boosting their magical talents with his own — turning them into a force to be reckoned with. His spells are incredibly powerful and noted to be extremely skilled in close combat. He's often used when the going gets tough, his various magics used to pull Devin out of tight situations.

Incantation: "Open, gate of the Eldritch Warlock." (開け、不気味妖術者の扉, Hirake, Bukimi Youjustsusha no Tobira)

Black Knight Apparition, Laverthregnus
Black Knight Apparition, Laverthregnus (黒騎士怨霊·ラベアスレグナス, Kurokishi Onryō, Raverusuregunasu): Heralded as one of history's most feared warriors, he's a knight that's known to have mastered swordsmanship to its highest degree; it's said that he had no rival during the time he was alive, proving his status as the strongest swordsman of his generation. Originally, he was a high-class knight who served the Royal Family of the Pergrande Kingdom — embodying the basic concepts of chivalry and honor, thus admired by both his peers and the country's ruler at that time. By his blade, he was able to end threats aimed at the kingdom singlehandedly; he was also able to slay many Demons and Dark Mages while saving the lives of many, gaining the praise of others on a continental scale.

It was until he encountered a certain infamous Dark Mage by the name of Zeref that his descent into darkness was inevitable; during his battle with the skilled sorcerer, he was cursed through the machinations of one of his many Black Arts — turning into a demonic warrior who only lived for combat, losing all sense of reason. His sacred weapon that he's been entrusted with for so long has been transformed into something more sinister, gaining powers unlike any other. After hearing news of his eventual "fall from grace", he ordered all of his knights to hunt him down and kill him — no longer wanting what was once a proud and revered warrior to shame his reputation; it was a decision that greatly saddened not only him, but those within the knightly order and the civilians who've heard of such ongoings. Upon finding him and after a lengthy battle — losing nearly over 90% of their forces, a testament to his new sinister strength, they were able to slay him — putting his once-tainted soul to rest..... or so they thought.

Sometime after they properly gave him a funeral, his spirit lingered — somewhat an aftereffect of the curse he was afflicted with, his new purpose was solely for the slaughter of all who've encountered him. It's estimated that he killed over tens of thousands of people, most of whom were highly-skilled warriors and mages over the course of three hundred years. He was eventually "put to rest" when he fought the wielder of Intetsukijin at that time, now sealed for eternity within the weapon's cold steel confines and subjugated to said user's whim through the machinations of its magic — becoming the fifth spirit in the series to be sealed.

As he's completely devoid of reason, no longer having remnants of his former self, he's easily manipulated — thus considered to be powerful weapon for the sword's wielder to freely utilize; Devin stated that he's one of the most useful spirits in his possession, his overwhelming power and skill being able to decimate the opposition.

Magics & Abilities: A juggernaut in his own right, he's considered to be one of Devin's more powerful summons — being an extremely heavy-hitter; his overall power almost equates to that of Gehenna's or Zegramelek's, which is saying much if one is aware how powerful the former two are. While relying little on magic, he's known to be a fellow master of both the sword and the martial arts alike; it's only sensible for someone like him to be deployed for close-range tactics.

Incantation: "Open, gate of the Revenant Knight." (開け、亡霊騎士の扉, Hirake, Bōreikishi no Tobira)

Primordial Chaos, Ogul
Primordial Chaos, Ogul (原始混迷·オグール, Genshi Konmei, Ogūru): An entity of an unfathomable nature, it's said to be a creature that crossed over from the deepest nether regions of the abyss in order to lay claim to the world of humans. It's also said to have been reverred as a God from once it came, having powers that's considered to be unimaginable to mundane mind — despite having no physical form. There have been many rumors surrounding it, with the general public making reference to it as a demon — even though such isn't the case, a part of a species that transcends the likes of such limited evil. For many millennia, it existed in the remote parts of the Human Realm — its domain filled with death and destruction.

According to various myths and legends told about it, there were many who went to challenge it in order to prove their strength — none coming back alive. This made it a force gone unchallenged for many years to come. It's only until its latest challenger was the wielder of Intetsukijin that it met its eventual downfall; after finding out its secret as a spiritual body, the user used Ethereal Subordination Magic to ensnare its very essence and trap it within the confines of the blade. Since it was something of the incorporeal nature — it barely put up resistance; with such victory under his belt, the user made claims to its domain, essentially becoming its new ruler.

A creature that barely speaks — having no formal way of communication, its the only one that doesn't communicate with Devin as it doesn't possess the method to do so; he merely comes to his beck and call, doing anything the silver-haired man tells him to. Despite this, Devin holds the creature in high regard, seeing him as one of his most reliable assets.

Magics & Abilities: As a being who can freely change his shape at will while possessing a myriad of curses at its disposal, he's seen as another well-rounded fighter; however, Devin uses his talents in a unique way — acting as a security system with a heightened sense of response. Uniting both attack and defense, it is a "perfect weapon" that acts as both his sword and shield; it's usually seen floating behind him and can act as a mode of transportation by merely shifting its shape. Like with the mechanized devil, he's usually given certain commands that it carries out when certain conditions are met.

Incantation: "Open, gate of the Formless Void." (開け、混迷虚の扉, Hirake, Konmeikyo no Tobira)

Quenchless Fury of God, Xaphanuer
Quenchless Fury of God, Xaphanuer (神の渓激情·ザファンヌエラ, Kami no Keigekijou, Zafanuera): According to the scripture that's accessible to high-class members of the Zentopian Church, Xaphanuer was originally a Seraph-level Angel who was in service of the Gods — noted to be the most loyal of his kind; it was thus that he was eventually promoted to the status of Archangel — considered to be one of the highest positions a normal Angel can ever obtain. As he was the embodiment of the gods' anger towards various transgressors, he was known to possess great power to carry out their judgment; it's known that he has interfered throughout most of humanity's affairs — specifically ones that dealt with the Gods in some manner, either imitating them or trying to achieve powers that are nearly equivalent to their own. This continued for many millennia to come; little did anyone know that his own power would be his eventual downfall.

As he eventually rose in power over the years, he started to gain the worry of the other Gods — having the potential to surpass them and eventually overthrow them; this hysteria got the better of them, causing a few to attack the loyal Seraph out of fear. Though Xaphanuer was able to escape their onslaught, he escaped the confines of his realms — no longer feeling safe. It was then that he was driven to madness by his betrayal of the very beings he's served for many millennia; after discovering the exact reason for such a treacherous act, he eventually "fell from grace" — becoming a Fallen Angel. It was then that he attacked various gods — major and lesser alike, sating his desires for vengeance while absorbing a fraction of their power, becoming steadily stronger. His rampage against them was put to an end when a God wielding the famed Intetsukijin managed to slay him during a lengthy battle, only to be a sacrifice; the fallen angel's spirit was sealed within the blade's confines, never to see the light of day unless called forth.

Devin notes that Xaphanuer has an eloquent way of speaking like Decarigorn and has millennia worth of experience, thus is able to give the young man sound advice when needed. However, he tends to be arrogant and prideful in his own power, thus sort of hard to workn with at times — especially when it concerns the affairs of deities and those who've worshiped them. He only summons him when the going gets rough, employing his skills along with some of his other summons.

Apparently, he offered to give Devin an Angel's Blessing, which would lead to a substantial increase of his overall power; however, the young man denied it — thinking that he wasn't worthy of such a gift, after hearing many stories told about it, much to the disappointment of the Angel — who openly admitted that Devin has the potential to utilize his powers to its utmost limit.

Magics & Abilities: An Angel belonging to the highest order, Xaphanuer boasts an incredible amount of power — enough for him to be feared by the very gods he once served. He's able to manipulate the elements of light and darkness to the highest degree while able to employ other forms of magic; while not as versatile as Decarigorn in terms of spells, he makes up for it in power. He also uses his physiology to his advantage, being able to counter weapon users and martial artists with ease, thus able to enter close-quarters combat against a multitude of opponents with no problem.

Incantation: "Open, gate of the Treacherous Angel." (開け、佞姦天使の扉, Hirake, Neikan Tenshi no Tobira)

Living Hex of the Nether-realm, Slothmync
Living Hex of the Nether-realm, Slothmync (在世呪詛の下界·シュールロスミンク, Zaisei Juso no Gekai, Shūruosuminku): Like its fellow shadowy brethren, Slothmync is an incorporeal entity that's derived from another plane of existence; considered to be a carnivorous creature by nature, it has consumed various beings that its encountered over the centuries, slowly growing in strength. It's described as a naturally malevolent creature, devoid of any positive traits; this is seen by the carnage it caused over the years after the disappearance of Ogul, killing large amounts of people and razing many lands in its abysmal shadow.

According to stories made-up about it, it has the ability to hide in the shadow of its victims — waiting for when their guard is down, eventually consuming them inside-out while staying within their shadow; it's impossible for a corpse to be found, as the victim is consumed whole. It's also said that the atmosphere where this creature is located becomes much colder and depressing, filled with fear and dread — a testament to its incredible powers. While it constantly hides in the darkness — having a natural fear of incredible amounts of light, its powers reach its peak on the night of a full moon; it's said that it takes on a more humanoid appearance during this time and is able to blend in with society — albeit for a brief time. This allows it to feed without arousing suspicion. Due to it being a mere shadow, it's appearance constantly changes to suit its needs.

Though the details are unknown, it was eventually defeated and eventually sealed within the confines of Intetsukijin by one of its former wielders; the shadow targeted him after becoming attracted to the energies that the blade was constantly emitting. Apparently, the wielder played a trick that allowed the shadowy entity to enter the blade without resistance, which was its greatest downfall.

Devin states that because of the nature of this creature, he mainly uses him during assassinations and bars him from being unleashed during battle, as it would eventually consume his opponents whole. He doesn't try reasoning with it — having no sense to begin with; it's kinda hard to control as well, which is due to its absence of such an important trait. He considers him more dangerous than Zegramelek, despite being less powerful.

Magics & Abilities: Due to its ephemeral nature, its considered to be malleable — thus can take on a variety of forms; it has heightened physical and magical power, thus able to overwhelm its targets. However, it tends to be weak to light-based techniques, thus not commonly employed against light mages. It has good assassination skills, as it's able to consume its targets without them noticing; due to its reckless and vicious nature, its uses lie outside of combat — deemed too dangerous for normal opponents to face.

Incantation: "Open, gate of the Malevolent Shadow." (開け、邪悪な蔭の扉, Hirake, Jākunakage no Tobira)

Apostate Witch, Eumociana
Apostate Witch, Eumociana (背教者魔女·ユーモシーアナ, Haikyōsha Majo, Yūmoshīana): The only female of the group, Eumociana acts as the healing, defense, and support of the entire series — her true potential seen either outside of battle or when Devin's or his allies' lives are at risk. She was originally one of the few saints in the Zentopian Church, heralded for her works for the poor and sick — using her abilities to heal many and converting over ten thousand people to the church's beliefs; this caused it to expand exponentially in a short period of time, something that the higher echelon of said faith believed to be a mere pipe dream — thus praising her as a "Holy Mother" (聖母, Seibō), much to her embarrassment — believing that she wasn't worthy of such a title. It's said that her abilities were greater than any other in the faith and that it's reached its peak on the day of worship, where her works would be referred to as an "act of God", causing many to flock to her to receive her "divine touch". At some point of time, she was granted a third-eye by the machination of the gods, recognizing her service to humanity; although she was quite dubious of such a gift at first, she began to praise the gods for giving her such a thing. Little did she know that such a "gift" would bring about her eventual downfall.

It's discovered that her eye had to the power of future sight, allowing her to see multiple futures and decipher events of various magnitudes, either good or bad; in exchange for such a gift, she must suffer the backlash of freely using a power that should only belong to the gods — coming in the form of endless nightmares involving her. While she was able to perform readings on a person's future with such accuracy, she was afflicted with constant nightmares — some of which caused her either physical or mental pain. It continued for many years, taking a toll on her health. It had reached a point where she was driven to lunacy and broke down in various ways; she later defected from the church and began to live her life in solitude deep within the nether regions of a forest located somewhere in the country of Sin. It was here that her descent into the darkness would occur.

Apparently, she met a Demon that could get rid of what afflicted her, but at a price — turning her into a Demon herself; due to her being in constant pain and showing extreme hatred towards the gods at giving her such a "curse", she accepted the Demon's offer — making a contract with it and turning her into a creature of darkness. While the power of the gods forever left her, she became one who only hurt others instead of helping them like she did before; she studied and practiced the Black Arts, with many denoting to her former specialties. For many years, she tested out her new powers on unsuspecting victims — killing most of them in the process; her demonic appearance and her heretical acts earned her the current epithet that's referred by. Her latest "victim" was the user of Intetsukijin; she tried to hex him, but after witnessing the power of the sword firsthand — being able to cut through most of her curses and dark powers, she desired the blade for herself. However, she later fell at the hands of it due to the user's skill with it, her spirit becoming part of the very thing she desired; for many years onward, her skills of healing, curses, and protection were used to aid the user of the ominous blade. Through unknown means, she was able to regain her sanity and innate kindness, most likely due to the energies within said weapon slowly changing her to become more obedient towards its user. Becoming aware of her situation and the crimes she's committed, she fell into depression for a time — finding ways to repent; it's through her decision to help the current users of the unholy weapon that she would find redemption.

Devin treats her with such delicacy and kindness after hearing of her circumstances which lead to her being sealed, showing some pity towards her and recognizing his plight being similar to hers in a sense. He also states that her relationship with him is similar to one of a mother and her child; Eumociana recognizes that Devin never had parents to care for him, thus decided to fill in the role in order to alleviate whatever loneliness he may have — something he's grateful for; she tends to comfort him and give him advice in an array of subjects, combat or no. She also chastises him from time to time and worries about the path he's walking. Since she's reverted back to her original kindness, she's one of the few that's considered to be reasonable by Devin's standards, thus able to communicate with her no problem. Though there are times where she's driven to lunacy and reverts back to her uncaring and demonic persona — only seen when Devin's life is in extreme danger.

Magics & Abilities: She's considered to be Devin's "White Mage", her magic being used for either boosting her allies, healing, or conjuring various defenses. However, she does have some offensive spells at her disposal in the form of hexes and minor umbral manipulation, but its severely lacking in comparison with the others. She also possesses average strength and little martial arts prowess, making her a bit weak at close-range.

Incantation: "Open, gate of the Heretical Nun." (開け、 外尼僧の扉, Hirake, Genisou no Tobira)

Perpetual Strife Embodiment, Kratos
Perpetual Strife Embodiment, Kratos (恒久闘争具体化·クラトス, Kōkyūtōsō Gutaika, Kuratosu): A being who was crafted for combat, Kratos's name serves his overall purpose — the physical embodiment of war and strife; he's considered to be a lesser god who's existence is pivotal in culling humanity, dwindling them in number thus letting them thrive. It's unknown how he was created — let alone summoned, but its theorized that he was formed from the residual negative energies of the gods, becoming the new embodiment of their anger after they've expelled Xaphanuer from their graces in fear of his ever-growing power; though he was a lesser god of war and combat, he looked more of a demon — typical of something that embodies another's anger, thus referred to as such by many cults and religious group who've worshiped the gods in reverence. Fulfilling his given roles, he's been stimulating strife amongst many species — causing some of the most gruesome wars known to the realms and is the cause of the extinction of many species, while meeding out the god's anger to those who've incurred their wrath through fraudulent acts and heretical teachings; like his predecessor, he continually grew both in power and wisdom while slowly gaining sentience and reasoning. Even when the gods learned of such development, they really weren't worried as he was considered to be their "pet" — confident enough that he would never betray them. Little did they now that his encounter with his predecessor would be his last battle.

After discovering that Xaphanuer was still alive after the assault, the gods feared of his vengeance against them thus commanded Kratos to go take care of him; when the two meet — seeing that Kratos was merely a "lap dog of the gods", the two fought a battle unlike any other, shaking the lands, rupturing the seas, and splitting the sky in two. It continued for many days with both sides being equal, something that the fallen angel didn't expect due to his exponential power increase he gained just before the battle; it was only through trickery that he was able to get the upper hand against Kratos and finally put an end to his life. As Kratos was made up of energies deriving from the gods, his death didn't go unwarranted, instilling a fear in them unlike any other; their "ultimate creation" destroyed by the hands of one who's previously served them without regret, only to be betrayed out of fear. This led to the events that would eventually caused Xaphanuer himself to be sealed; little did they know that Kratos' spirit was still lingering, his power was going strong.

The godlike entity wandered for some time, achieving his given roles and slowly gaining even more power and wisdom; it reached a point where he could stand on equal terms with his creators, something they themselves feared. However, he decided that his role as their loyal servant was over and decided to rest for all eternity; he sought out the current user of Intetsukijin and sealed himself within the blade's confines, thus becoming ally to its users. It's said that he confronted and battled Xaphanuer when the two encountered each other within the blade, only to end up in a draw; as Kratos never held a grudge against the angel for his death, he forgave him — showing a form a mercy that the angel never expected from one who's a servant of the gods. After being informed of the current events, the two are now on equal terms with one another.

Devin notes that Kratos is a loyal and dedicated individual who will do anything to guide its master to victory; as a being who's specialized for combat, he's considered to be one of, if not the most useful spirit out of all contained within the blade, thus commonly employs him in combat. Though he's silent for most of the time, he's known to be very wise and an intellectual individual, even more so than his fellow peers; this is most likely due to his accumulation of knowledge over some time, becoming savvy to most things the others aren't. Since he has many similarities to Devin, the two get along quite well.

Magics & Abilities: As he was built for combat, Kratos is viewed as one of the most versatile summons, being completely balanced out in all areas. He often shifts his body parts into various weaponry and has extensive knowledge of various combat styles employed and created throughout human history; when synchronized with Devin's movements, his destructive power increases exponentially — turning him into a force of pure carnage.

Karmic Beast of Everlasting Hellfire, Gehenna
Karmic Beast of Everlasting Hellfire, Gehenna (命獣の常業火·ゲヘナ, Meiju no Tokogōka, Gehena): Another being of incredible power under Devin's control, it's said to be another Wyvern of great potential; in fact, it lived in the same era as Zegramelek, being one of his many subordinates and acting as his right-hand during his tyrannical reign. Gehenna's loyalty was unlike any other, as he followed Zegramelek as if he were some kind of god; his zealous attitude towards his master's ambitions were well-known through his kind He embodied all the traits that the creature lacked, serving as his foil — something that the creature needed in his right-hand, as differentiating opinions will help the ruler understand his enemy's line of thought. Something that's been said about him on multiple occasions, Gehenna has one of the most superlative appearances of his kind — something that can only be matched by one of equal or greater beauty; many tend to take note of the pattern of his glistening scales that truly shines when exposed to heat or sunlight, being a unique type of red not found anywhere else in existence. It's been said that such coloring alludes to his mastery over his own magic along with many others — something he confirms to be true, having reached such a condition with many years of honing his skills to its utmost limit; this confirms that his species can evolve when they mastered various types of magic along with their unique element, gaining a new appearance that reflects such an achievement. He's noted to be one of the few beings that was able to combat Zegramelek on equal grounds, something many are unable to do lest they have either great amounts of power or great numbers on their side. It's due to this, along with its kind and sincere nature, that many Wyverns and Dragons alike looked up to it and followed what it said; Gehenna had authority over many legions of Wyverns, being their supreme commander — second only to their king.

When the Dragon-Civil War occurred, he naturally sided with the Anti-Human faction — although he held humans in high regard, once stating that without their existence, both Dragons and Wyverns would eventually starve to death and force to turn to.... alternative methods. Like his master, he showed off his various magical talents, decimating those who've opposed him; he's singlehandedly caused severe amount of casualties, instilling a fear so great that no other would dare challenge him. His catastrophic power combined with his sublime appearance caused many to give him various names, one of which was "Veralegna" (, Berareggunā; lit. "True Abysmal Black Flame Lesser Dragon of Everlasting Glory") — making reference to his potential role as the "Second Black Wyvern King". However, like his master he so faithfully served, he met his eventual end at the hands of Acnologia — the Human-turned-Dragon with an insane amount of power at his control; his magic was ineffective against this new being, thus all efforts he made were deemed moot. After the civil war ended — the aftermath being too great for everyone to bear, his spirit wandered the planet — seeking out the very being that took both his and his master's life.

However, fate would play a cruel joke in his quest for vengeance, as he encountered the current wielder of Intetsukijin. Upon sensing his master's presence within said weapon, he asked the owner if he can be apart of it; although hearing of the conditions — losing all freedom, forever being bound by the powers it possesses, thus losing a chance to achieve what's needed of him, he decided to put it aside in sake of his master's well-being. Through the weapon's ominous powers, he was sealed — forever becoming enslaved, thus becoming one of the famed beasts of the series. Though his eventually sealing was much to the chagrin of the being he so faithfully served, he's happy with his decision nonetheless, being able to stay by his side once more.

Devin notes that although he's the subordinate of Zegramelek, he's more reasonable than the Black Wyvern King, being much more kinder, friendly, and sincere; on various occasions, he would often follow Devin's orders when summoned — one of the conditions he made with the previous user before the beast's sealing. Not only that Devin goes on to say that he treats everyone equally, which contradicts his somewhat scary, yet awe-inspiring visage, lacking the extreme amounts of cruelty and discrimination that his master possessed. Something that he tends to show at times, he's known to worry about Devin's safety despite knowing of his current goals in life; nevertheless, he supports his decisions — thinking it will turn out for the best. Devin is very close to him, more so than any other spirit in the series — barring beings like Eumociana, Kratos, and Nuriyamidoh.

Magics & Abilities: Like his master, Gehenna is someone to be feared — having the ability to mow down all that stands in his path, his destructive power is unlike any other; he's known to have mastered over a variety of magic and his unique physiology allows him to participate in close-range combat. As one who nearly equates his master in terms of power, Gehenna one that's not to be messed with. His true potential is seen when he's deployed with said master, as the two Wyvern's destructive power multiples to an unknown degree when in each other's presence. Devin notes that him alone is enough to do the deed.

Old Man of the Nuclear Winter, Jägeryst
Old Man of the Nuclear Winter, Jägeryst (核の冬の老翁·イェーガーイスト, Kakunofuyo no Rouou, Yēgāisuto): Someone that Devin knew for a long time, he's related to the mysterious benefactor that gave him his signature sword; he's also considered to be one of the few people that Devin looked up to, the old man acting as his mentor for a brief time. In fact, most of Devin's skills came from this old man — despite his somewhat frail appearance, the most obvious one being able to create various types of poisons and makeshift weaponry — chemical or otherwise. According to Devin, he was once known all over Ishgar as a master of poisons and the like, the concoctions he made are enough to bring about the desired effects — whether its to cure a person's illness or bring about a calamity the likes of which can't be properly fathomed. Some of them were banned by the Magic Council due to the potential threat on a global scale, something that was intended for a few of them. It's such that many have gone after either him or the potions he made; they were most sought after either during times of war or great strife. He used various methods to create his potions, most of which were passed down to Devin — which he utilizes on occasions in honor of him.

Due to his advanced age, he didn't have much longer to live; with the remaining years, he spent most of his time with Devin while making sure that the boy grew up healthy until his eventual passing. It's known that he was the one who sent Devin to live the orphanage he grew up in for some time, and after his death, his spirit remained in order to watch over the boy. After Devin awakened to the realm of the spirits and was able to see the souls of the dead, he was re-united with the one he cared for the most; sometime after Devin received his weapon, the old man decided to become one of the myriad spirits trapped within — fully aware of his fate after hearing various legends told about it. Devin being vehemently against it, believing that his caretaker should rest in peace, he finally gave into his wishes — tearfully saying goodbye to him before sealing him within the sword's confines.

The relationship between these two is like grandparent and their grandchild: one filled with much love and care; in fact, their relationship hasn't changed at all, even with the old man's death. Devin openly admits his love he has form him, as he was the one who raised him like his own child despite not being related to one another and showing no hatred after discovering of the boy's demonic blood. He refers to the old man as "Ōji-sama" (祖父様, lit. "Honorable Grandfather"), rather than by his given name like he does with the other spirits in the blade — commonly seeing it as a form of respect; typically, he's one of the few spirits he holds in high regard above all others.

Magics & Abilities: Like with Eumociana, he's employed as support — using the various potions and poisons at his disposal to weaken the enemy to some degree or to strengthen his allies in some way; he's shown to be good in close-range, having taught Devin to some degree, but because of his age — he doesn't possess the strength that some of the other spirits are capable of producing.

Rampant Machine Devil, Tyrvalex
Rampant Machine Devil, Tyrvalex (跳梁跋扈機械魔·ティアバルエクスル, Chōryōbakko Kikaima, Tiabaruekusuru): One of the most unusual summons within the series, he's considered to be one of three spirits that's been captured by Devin personally; the silver-haired man notes that despite its overwhelming power and high-class technology at its disposal, it was pretty easy to put down. According to him, it was originally a corpse of a powerful Demon that the Magic Council procured sometime ago — using it in one of their various projects to improve their technology while finding ways to combat various threats made against Ishgar — using less manpower in the process, and by extension — prevent needless sacrifices. After many trials-and-errors done on the corpse — fully analyzing its genetic make-up and finding what can be used on it without accidentally reviving it, they succeeded into created the first artificial intelligence super weapon — one that can be used at any time, acting as substitution to weapons such as Face and Etherion. Finding a way to test its capabilities and collect data, it was programmed to hunt down and destroy specific targets — usually ones of S-Class ranking or possibly higher; proving its might to its creators, it essentially defeated a slew of enemies that was recorded in its programming using the given weapons and other tools in its possession — all of which was done in mere moments. While the creators was gloating about their "success", little did they know that such battles would prove fatal as it only serve to waken the demon that was used as the template for their so-called "ultimate weapon".

Sometime after conquering what would be its "last target" — the cumulative damage that it took over time began to show in the form of slight changes in its original programming; the final nail on the head was when it was exposed to and subsequentially absorb a large amount of Magical Barrier Particles — the very substance that made up a Demon's body. This caused the "Demon within the machine" to awaken, thus going on a rampage the likes of which couldn't be fathomed; many towns and cities were razed to the ground and thousands upon thousands of people succumbed to its incredible powers and died. When the upper echelon of the Magic Council heard about such events from one of their subordinates and getting pictures capturing the carnage it was unleashing on their continent, they momentarily fell into despair before ordering its elimination. It's during this time that Devin accepted the mission from the council, along with many other guilds to stop the rampaging creation they had so much pride in.

As the final person to find the mechanized creature — all others before him were either heavily injured or dead, he used all of his power to suppress the being, which he notes was rather easy after figuring out its fighting style — a compilation of other fighting styles and techniques the council had archived. In order to prevent such a meaningless rampage from ever happening and wanting to make use of its power in the near future, he destroyed it and trapped its spirit in Intetsukijin, adding the machine-demon to the series; normally, machines aren't affected by Ethereal Body Subordination Magic as they have no souls, contradicting what another magic says entirely because it's bullshit if someone with enough brain cells thinks about it, but since its basis was that of a Demon's, it was possible to pull off.

Devin notes that this machine was one of its greatest summons, having various abilities compiled in its database; while maintaining its demonic traits, it holds a slew of tactics and combat experience collected from the various battles its participated in. As a machine, it can easily be programmed — something that Devin does from time to time to keep major damages from severely affecting its programming — something he noted that Magic Council was too ignorant to do, as they were too busy gloating in their own genius. The machine is noted to be at least the same size as someone of Qelnaidium's stature — a beast noted to be very large in its own right; when combined with its somewhat demonic design and overwhelming power, it's a force to be feared. Devin tends to appreciate this machine greatly, seeing it as more of an ultimate weapon that he can freely use — if anything.

Magics & Abilities: As a high-grade machine crafted from the corpse of a high-class demon and loaded with various data from the Magic Council's archives, Tyrvalex is considered to be another juggernaut in Devin's possession; it's also an all-rounder, having good offensive and defensive powers respectively. While it uses the various weapons its equipped with, it also participates in martial arts and spellcasting — the latter only being possible because of having a demon as its core and basis. He's known to be match for any opponent it stands against, being able to use a myriad of tactics to cause their inevitable downfall.

Pole Star Rakshasa, Qelnaidium
Pole Star Rakshasa, Qelnaidium (妙見羅刹·ケルナーヂアウン, Myōken-rasetsu, Kerunādiaun): Though it's a beast of unparalleled power, it's considered to be a lesser member of the group — being much weaker than the rest of his brethren; it's one of the three beasts that's been personally captured by Devin while on a mission for a client, considered to be one of the few missions he did upon joining Koma Inu. Apparently, it was originally a Demon who slowly gained power by consuming the flesh of all that encountered it; this continued for many years, leading to many disappearance cases going unsolved. It continued to evolve until reaching its current form, gaining both a slew of versatile abilities and a heightened form of intelligence at the same time — making it one of the most dangerous of its kind, despite its bestial appearance.

Devin stated that many who went after it met their eventual end, only furthering to increase the entity's already unfathomable power; by the time he encountered it, its power had reached a pointy where it seemed to be nigh-unbeatable to the average mage. After a lengthy battle that left both in a near-death state, it was through sheer willpower that Devin was able to find the strength to kill said beast and eventually seal its spirit within the confines of its new prison, much to its displeasure. Since then, Devin has always used the beast to his beck and call — its various powers and knowledge coming in handy in most situations.

The sheer size of this being is roughly half that of the mastodonic Zegramelek; combined with the ominous black aura that constantly surrounds its body — making it even more feared than when it was alive, it's able to instill fear inside those who face it — with the exception of a select few. As a being with an incredible degree of reasoning, he willfully works alongside Devin — fully well knowing that there's no escape from its new home; it also partially stems from the great deal of respect it gained for the silver-haired man, the young warrior giving it an entertaining battle unlike those who've faced it before. In return, Devin treats him with more respect than most of the other spirits in the series, always listening to what he has to say and taking his given advice. It seems that the to have grown accustomed to each other as time passed, enough so that Devin typically uses him as a mount in certain instances — fully depending on his physical versatility across various types of terrain.

Magics & Abilities: Although it's a beast of incredible strength, it doesn't compare to other spirits in terms of power; however, it makes up for it using its overall mobility, colossal strength, and unique physiology — being able to hunt down and subsequentially devour its opposition. As it possesses both magics and curses, it can easily hold its own in combat.

Wicked Spirit of Minor Evils, Nuriyamidoh
Wicked Spirit of Minor Evils, Nuriyamidoh (邪気の群小悪·ニューリヤミド, Jaki no Gunshōaku, Nyūriyamido): Like Qelnaidium, he's not considered to be part of the original thirteen Dark Necrospirits due to his lack of power; in fact, he's considered to be the weakest in the group — being a "young demon", thus tends to be looked down upon by a few of its members. Despite this, it tries its best to please its current and only master, Devin.

According to Devin, he managed to save the little guy when he was being attacked by a larger Demon; from then on, he's been secretly following Devin for while, hiding his presence from the silver-haired man and watching him from afar — waiting for a chance to repay the favor. As time passed, he grew to admire Devin's power and bravery in the face of adversity, thus began to reveal himself to the young man; initially, Devin found him to be a bit of annoyance — telling it to buzz off from time-to-time. However, as he saw it effort it put into trying to aid him on various occasions, he grew to appreciate him a bit; it's only when it nearly died trying to save Devin from a surprise attack from an unknown entity (presumably a creature similar to Slothmync), that the young man had showed genuine concern for its safety — bursting into tears after thinking it died. In an attempt to save its life, he sealed him within the confines of the blade in hopes that he can properly recover.

Out of all of the spirits within the series, he's the only one who genuinely cares for Devin's safety and sees him as a friend rather than a master; he's also the one to be the most emotional, expressing its feelings and being more opinionated.... even though it only says one word nearly all the time. He's known to have developed a sixth sense when it comes to its master, feeling the same emotional pain that he feels — noted to be a sign of its closeness with Devin. Oddly enough — something noted by Devin and the other spirits in the series, he's able to leave the confines of his prison freely without feeling any aftereffects; it's theorized that it may be due to its relationship to its master or may be the by-product of its ever-growing power. This garners it a bit of respect from the other spirits, a feat that not even they with all their power, could do. Devin notes that he's glad that the creature is the only one that has this ability, fearing for the worst should the other spirits in the series gain such an ability. Devin states that he usually comes out whenever its in a playful mood — begging its master to entertain it for a bit, or when his master is going through some emotional turmoil — going out of his way to alleviate him of his trauma, using his physiology to help perform the deed. He often sits on top of Devin's head or float around the young man whenever he's around, usually having a gleeful expression; Devin doesn't mind this though, finding it to be kind of relaxing at times. It's affectionately referred to as "Nuri" (ニューリ,  Nyūri), as that's the only thing it seems to say. It appears that it can be seen by others, but only if he deems them friendly, using a special power that allows itself to freely cloak its presence.

In all honesty, he's more of a pet if anything, going by the way he acts and shit. Think of him as the mascot of the friggin' group, and probably the only one that isn't batshit insane in some way.

Magics & Abilities: As the weakest of all the spirits in the series, it barely has any powers that can be deemed as recognizable; however, after absorbing the essence of the other spirits within the blade, it slowly grew in strength and versatility — despite its overall small frame. In recognition of such a feat, it was given an Angel's Blessing by Xaphanuer — a feat considered to be an impossibility due to its status as a Demon, especially one of a lower-class. Beyond anyone'e expectations, it was able to receive such blessing with succumbing to pain; Devin notes that it may be due to the genuine feelings it has for the silver-haired man, only existing to protect him. This causes its power to grow to greater heights, gaining a slew of new abilities and unlocking its full potential. While still seen as the weakest, Devin tends to employ him in fights — but only when the spirit feels that its master's life is in grave danger, doing anything and everything in its power to protect him.
