Celestial Spirit Magic (Per)

Celestial Spirit Magic (星霊魔法, Seirei Mahō) is a Holder Magic, Light Magic, and Spirit Summoning Magic which is utilized by certain magicians whom have made a particular contract in order to call upon the power of Celestial Spirits, a group of seeming light-inclined spirits that embody numerous constellations of the zodiac, which is the circle of twelve thirty degree divisions of celestial longitude employed by western astrology, representing various astronomical constellations overall, enabling the caster to summon these creatures in order to assist them, oftentimes acting as per the caster's orders for all sorts of purposes whether it be for offense, defense, and other capabilities, functioning as a guardian for the wielder within the heat of battle.

Description
As described above, Celestial Spirit Magic allows the user to call upon the power of the Celestial Spirits, whom are spirits from their own dimension which runs parallel to and  and is known as the. Just like most forms of Spirit Summoning Magic, which involve the manifestation of a spirit, an extremely powerful type of legendary creature that's classified non-corporeal substance contrasted with the material body which includes those brought into the physical realm through the power of other magicians such as Familiar Spirits, Planetary Spirits, Elemenian Spirits, Virago Spirit, the Celestial Spirits that the wielder of Celestial Spirit Magic summons are known to be somewhat holy, divine and sacred, commonly manifesting as pure magical energy or semi-divine energies that are not of this realm, and per the association of stars with light, the Celestial Spirits seem to take upon a form of hard light and have abilities not dissimilar to Light Magic. Like all forms of Spirit Summoning Magic, the Celestial Spirits are able to be brought from their Celestial Spirit World into the current realm where the caster resides through the usage of a which acts as a catalyst, in this case, said medium are, are highly stylized keys that open up a dimensional gateway within the spirit's world as to enable travel to the caster's world. These Keys are commonly separated into two classes: the more common which represent many constellations and the extremely rare  that embody the twelve signs of zodiac; these catalysts are counted in Units collectively without regard of Gold or Silver, and a Celestial Spirit Magician is noted by how many Units they have obtained; however, it should be noted that potentially many more types of keys exist.

In order to harness Celestial Spirit Magic in the first place, a magician is required to forge a pact with the spirit that they wish to fight alongside them; the initiation process is invoked by the hopeful contractor receiving the key and opening a dimensional gateway for the very first time. When a Celestial Spirit Magician receives a Key and opens its Celestial Gate for the first time, they have to set up a contract with the respective spirit. This contract consists of asking the spirit which days it can be summoned by the magician. This simple agreement forms a dedicated, serious bond between the Spirit and summoner. However, under certain circumstances, i.e. during battle, a contract can be asked to be completed later. Contracts can be broken if the magician gets arrested, releases the spirit by him/her self, or dies. When a Celestial Spirit Magician summons a spirit, it appears directly next to them, as that's where the gates to the Spirit world had been opened. It appears as if it is almost, if not completely impossible to summon spirits elsewhere. The spirits must also abide by certain rules enforced by the, the ruler as well as the absolute strongest of all Celestial Spirits. The only rule is that a spirit may not directly or indirectly kill its summoner under any circumstances. When the gates are closed, it is required from both the summoner and the spirit to agree upon the gate's closure. However, spirits can also be "forced closed" in battle, which means they can be forced back into the Celestial Spirit World by the summoner's will, though not every Celestial Spirit Magician is capable of doing that. Celestial Spirits also have different categories of sorts, that fall under the basic summoning conditions from their owner; if trust between the Celestial Spirit and the Owner is not an issue, contracts can be temporarily dissolved. It also seems that if the Celestial Spirit is strong enough, they can use their own Magic to stay in the current dimension, when/if the contract is not in action. The strength of the Celestial Spirits is affected by the magical strength of their summoner as well.

In any case, when invoking the activation sequence of Celestial Spirit Magic, the wielder of Celestial Spirit Magic focuses intently as they intensify the volatility of the magical energies that are dwelling within their Magic Origin as to excite them exponentially while grasping the summoning catalyst for this form of Summoning Spirit Magic, their Celestial Spirit Gate Key, they perform a small downwards slicing motion with the object, the tool going from being suspended slightly above the caster's head to almost touching the surface where they stand - from here, the caster releases the voluminous quantities of energy outwards from their body ever-so-slightly, the Celestial Spirit Gate Key and their emotions being used in order to take the concept of magic equaling the feelings of the magician to its absolute zenith – fuelling the fused energies with positive emotions, the user is capable of initiating the usual fusion of ambient eternano that's saturated throughout the vicinity and their own magical power, the Celestial Spirit Gate Key generating a whirling torrent of golden energy from the two edges of the key while this is happening. The caster's Magic Seal is projected outwards overlapping the Celestial Spirit Gate Key, which, in conjunction with the tool acts as a medium between the caster's own thoughts and the mortal plane – their imagination is the catalyst for the formation of the being, with the user's thoughts and feelings resonating with the Magic Seal in order to shape it into a form that's most desirable, the sequence so far alerting the Celestial Spirit, whom is still residing within within the, to the task at hand which must be accomplished, prompting them to get up off of their lazy arse and enter the transdimensional portal manifested before them and enter the alternate plane of existence which the caster is doing battle in. The arcane energies that are coursing around within the Magic Seal grant the Celestial Spirit physical sustenance, golden energies produced by the process spiralling around as the energy forms enter the portal. The Celestial Spirit utilizes the caster's positive energies and their Magic Seal in order to "solidify" and stabilize their existence within this world, hardening and forming – upon the final steps of the magic's activation sequence, the Celestial Spirit that is brought into the current plane of existence steps out of the Magic Seal. The newly summoned Celestial Spirit then emerges from the portal which twists shut and explodes with light, with the magical energy used to summon it, now coloured in accordance with its traits, orbiting around it.

After leaping from their dimensional gate and appearing in this current plane of existence, depending on how much of their magical energy that the user gives the Celestial Spirit, the holy spirit attacks and then leaves, or it will stay and continue to attack until defeated or its time runs out. Like most forms of Spirit Summoning Magic, the Celestial Spirit summoned through this magic is directly affected by the magical strength of their summoner, meaning that the larger quantity of arcane energy that's dwelling within their body, the more time the Celestial Spirit Magic can stay within the human world and assist the caster as well as their strength will increase. The magical levels of the Celestial Spirit are charged by giving and taking damage in battle, or avoiding an attack. After the respective Celestial Spirit's magic is launched, the magic levels returns to the state it was in prior to the summon, meaning if the level was full before the spirit was summoned, the spirit can launch two spells in a row. When a spirit is defeated the level is reset to zero. Additionally, summoning more than one Celestial Spirit uses up a lot of the summoner's Magic ability which may even lead to their death. However, some Celestial Spirit Magicians have shown the unique capability to summon multiple spirits at the same time. On various occasions, some spirits have been shown to be able to summon themselves without the need of their owners. The Celestial Spirits have been shown to possess the ability to communicate with their contractor via using the Celestial Spirit Gate Key as a medium through an exceptionally powerful form of telepathy without being summoned; additionally, in accordance to their summoner's thoughts and feelings, a Celestial Spirit is able to invoke a peculiar form of transformation in order to alter their appearance to suit what the summoner wishes for Celestial Spirits also have different categories of sorts, which fall under the basic summoning conditions from their owner. It also seems that if the Celestial Spirit is strong enough, they can use their own magical energies to stay in the Human World, when or if the contract is not in action.

Spells

 * Summon (召喚, Shōkan): Not really a spell per-se, but rather, the basic incantation of sorts that the user of Celestial Spirit Magic declares in order to activate the magic; it is similar to the "Summon" command of other Spirit Summoning Magics - as one may have guessed, the invocation of Summon is what enables the travel of the Celestial Spirit Magic to the dimension that the caster resides in by using the Solomon's Key as a catalyst. In any case, when performing "Summon", the caster announces "Resound, light of the stars" (鳴る, 星の輝き, Naru, Hoshi no Kagayaki) as they induce the usual activation sequence for Celestial Spirit Magic; this provokes the visual appearance of shining golden orbs which float out from the magician's Magic Origin and encircle them preceding the selected summon's appearance, as they converge into the form of their Magic Seal, which brings the Celestial Spirit beings from their imagination into the mortal plane using the glyph as a medium, allowing the Celestial Spirit to step out of the Magic Seal, ready for the purpose that they were born for, whether it be for battle or other purposes, such as doing chores. Upon manifestation, the mere presence of the Celestial Spirit begins to slowly but surely drain the summoner's magical energy reserves while the divine spirit assists them in any way possible; and depending on how much magical energy that the caster expunges into the formation of the seal which brings them into the current state of existence, the being attacks the foe a few times before returning to the Celestial Spirit World, or it will stay and continue to attack until defeated or its time runs out. In addition, summoning more than one Celestial Spirit uses up a lot of the summoner's magical energies, which may even lead to their death or a quick corruption and subsequent possession at the hands of the summoned creatures if they keep the multiple Celestial Spirits around for too long in their current realm. However, if they do manage to manifest more than one Celestial Spirit at a time, it bestows upon the wielder of Celestial Spirit Magic a greater amount of flexibility in battle, as they are capable of combining the powers of multiple holy spirits - both physical and magical - for stronger attacks in a manner not dissimilar to the likes of a Unison Raid; on that note, a magician is able to harness their own magic in combination with their summoned Celestial Spirit to dramatically bolster the capabilities of the proceeding blow. On various occasions, some spirits have been shown to be able to summon themselves without the need of their owners. Alternatively, the caster is capable of just summoning the powers and abilities of a Celestial Spirit instead of the entire being; when performing this variant, the user only performs half of the physical motions required to summon their Celestial Spirit being of choice; this, in turn, sends a notification to the Celestial Spirit which resides within the Celestial Spirit World as to simply not appear, but send their power instead. In an instant, the Magic Seal will manifest out of thin air, but when it opens, the Celestial Spirit does not leap out—instead, a powerful spell of the Celestial Spirit's choice will burst out, aimed at the enemy. This ability grants a user with low magical power more choices in battle, as the magical power cost is reduced to a quarter of the original cost, allowing them to summon multiple attacks at once. Interestingly, this ability can be combined with any other type of summoning, and the Magic Seal used to bring the Celestial Spirit to this world, when summoned by this ability, can be strategically moved telekinetically by the magician, allowing them to be used as makeshift shields or even battering rams.
 * Force Gate Closure (強制閉門, Kyōsē Hēmon): Force Gate Closure is a sub-technique of the "Summon" activation technique; Force Gate Closure enables the wielder of Celestial Spirit Magic to forcibly return the Celestial Spirits to the Celestial Spirit World. This can be performed at any time, including during the heat of battle or even during the middle of the magic's activation sequence. Closing the gates requires a mutual agreement from both the summoner and the spirit. However, at higher levels of mastery over this magic, some wielders of Celestial Spirit Magic have demonstrated the ability to force the gates to close in battle, compelling the Spirits to return back to the Celestial Spirit World.
 * Recompense Summoning (代償召喚術, Daishō Shōkanjutsu): Recompense Summoning, like Force Gate Closure as mentioned above is a sub-technique of the "Summon" activation technique for Celestial Spirit Magic - Recompense Summoning opens up the possibility for a summoner to summon the, the greatest of the Celestial Spirits before making that possibility an actuality. In any case, when performing Recompense Summoning, the wielder of Celestial Spirit Magic is required to fulfill several conditions before bringing the strongest of these holy spirits into the current plane of existence, as the Celestial Spirit King does not possess a physical key - for one, instead of allowing their usual Celestial Spirit(s) to break their contract or a variety of outcomes, the caster, if they possess enough magical energy within their arcane organ to summon at least a trio of Celestial Spirits simultaneously, is capable of taking one of their Celestial Spirit Gate Keys before breaking it, calling the Celestial Spirit King's name to the heavens - from here, the wielder of Celestial Spirit Magic induces the usual activation sequence for Celestial Spirit Magic; this provokes the visual appearance of shining golden orbs which float out from the magician's Magic Origin and encircle them preceding the appearance of the Celestial Spirit King, opening a gateway that manifests within the Celestial Spirit World for him to enter, as these orbs converge into the form of the caster's Magic Seal, allowing the ruler of the Celestial Spirits to appear within this world, fully willing to fight by the caster's side. Of course, the Celestial Spirit King follows the rules of regular Celestial Spirits, except he is vastly more powerful than the rest. Whichever Celestial Spirit Gate Key is sacrificed to summon the Celestial Spirit King will then crumble to pieces, and will henceforth be unusable. As such, the Celestial Spirit which is associated with said key will no longer be able to travel to the magician's dimension, therefore making Recompense Summoning the very last resort.
 * Wrought Iron Summon (錬鉄召喚, Rentetsu Shōkan): Wrought Iron Summon is a special variant of the regular Summon spell; when performing it, the user generates a "band" of light that waxes and wanes, extending in front of the user for as long as they wish—the "band" is completely composed of celestial energy, from the same type that Celestial Spirits generate. When Wrought Iron Summon is manifested, the user inserts as many of their Celestial Spirit Gate Keys into the "band" of light, before turning them all—the "band" acts as a conduit for the Celestial Spirit gates, and seems to be from the Celestial Spirit World, meaning that it costs the caster absolutely zero percent of their own magical power. In any case, when Wrought Iron Summon is activated, the user summons as many of their Celestial Spirits of any kind as they wish for, overwhelming the enemy through strength in numbers. However, this does have one tiny drawback—the Celestial Spirit Gate Keys which are used in the "band" of light on the far left and far right hand sides absolutely have to be that of a Gold Key, or else the Wrought Iron Summon will not work as a powerful presence can only uphold said celestial energy.
 * Celestial Cross Fuse (, Seresutiaru Kurosu Hyūzu lit. Celestial Elegy: Two Hearts Beating As One): Celestial Cross Fuse, oftentimes referred to as the "" is a Celestial Spirit Magic spell that makes full use of a summoner's link with their Celestial Spirits in order to incorporate the power and Magic of the Celestial Spirits they summon through their contract into their existence, which manifests itself in the form of a change in attire and a tattoo of the Celestial Spirit's seal on their body. In any case, when performing Celestial Cross Fuse, the wielder of Celestial Spirit Magic focuses intently as they intensify the volatility of the magical energies that are dwelling within their Magic Origin as to excite them exponentially while grasping the summoning catalyst for this form of Summoning Spirit Magic, their , they perform a small downwards slicing motion with the object, the tool going from being suspended slightly above the caster's head to almost touching the surface where they stand - from here, the caster releases the voluminous quantities of energy outwards from their body ever-so-slightly, the Celestial Spirit Gate Key and their emotions being used in order to take the concept of magic equaling the feelings of the magician to its absolute zenith – fuelling the fused energies with positive emotions, the user is capable of initiating the usual fusion of ambient eternano that's saturated throughout the vicinity and their own magical power, the Celestial Spirit Gate Key generating a whirling torrent of golden energy from the two edges of the key while this is happening; instead of being summoned, the wielder of Celestial Spirit Magic sends a telepathic message to the Celestial Spirit associated with the key they're holding as to combine their power - due to the user holding a contract with them, the spirit has a special "magic link" with the user, essentially a contract of sorts that they can annul at any time. By synchronizing their magical power frequency with that of the spirit's when the two are in close proximity through this telepathic link, with the spirit's approval, the user can perform this spell; which merges the magician and the spirit, integrating the spirit within their body. This allows the magician to replicate the powers of the spirit; filtering out magic (known as drawing) from the spirit and storing it ready to be used by the user. This allows the user to possess near superhuman abilities, such as increased speed and strength, as well as being able to use the spirit's magic. When the magician and their spirit are merged, two kinds of beings are brought together, and since the user possesses a comparable consciousness, the spirit will lose their solid form and can only manifest for limited periods of time while the merging is occurring; giving the user superhuman strength and enhancing their body functions. The merger grants the user an extreme boost in power; giving them access to new abilities, including executing powered-up spells; and when entering fusion mode, a pair of white feathered wings will emerge from the user's back. The merger can only be executed when the user gathers enough eternano; however. In order to activate the merger, the spell has an "limit meter" that fills as the user collects eternano; which are glowing orbs of light that appears whenever an attack is landed or an attack is blocked; the user automatically absorbs eternano as they move around the area, but not while attacking or being attacked. When the user can enter the merger, the user begins to glow orange. Once the merger is entered, the user's magical power slowly drains, and the merger ends when it is depleted. The rate at which the power drains can be lowered by using certain accessories and equipment pieces. While in the merger, the character can still collect eternano, refilling their power as it depleted. While in the merger, the user slowly begins regenerating their stamina; while they gain a higher chance of obtaining a critical hit; as well as generic bonuses as special attacks, increased damage, and other enhancements. Entering the merger blocks any spell the opponent is striking the user with and knocks them back; however, this can be a double-edged sword, as the user's current magic is cancelled out when activating the mode; but despite this, this drawback can be morphed into a blessing, letting attacks be chained together in new ways. During a successful merge, striking hair or pupil colour changes become apparent, and it will even change the colour of clothing the user is wearing at the time; additionally, invoking Celestial Spirit Magic grants the caster the ability to use Heavenly Body Magic and Light Magic in addition to the magic of their spirit when fused. The magician can always initiate telepathic contact with the spirit. However, in the case that that the user loses consciousness or the spirit for any other reason has to assume full control over their shared body the spirit creates a so-called "Internal Space" (内部空間, Naibu Kūkan, pocket dimension), where the user can communicate with the spirit in safety and even recuperate. In a partial use, Celestial Cross Fuse completely drains the user's full magical power to recover from a foe's attack and slow down the opponent for six seconds, or until a spell is landed. The duration of this period can be adjusted by the user's magical power levels. During this time the user's attack cooldown is reduced to nothing, allowing the user to link together several powerful spells one after another; even spamming what would be considered spells with a normally long casting time. Also, if the opponent is evading, the user can still continue their assault against them, as the foe doesn't receive temporarily invulnerability during this method.
 * Spirit Convergence (スピリット・コンバージェンス, Supiritto Konbājensu): Spirit Convergence is a special Celestial Spirit Magic spell that enables the user to combine their Celestial Spirit Gate Keys into a new key—and thus, a new spirit. When performing the Spirit Convergence, the user shrouds their Celestial Spirit Gate Keys in their magical energy, before using it to break down the physical matter that the keys are composed of temporarily and merging the eternano particles that the spirits are made out of which is stored inside the keys, merging all contracts into a single, great one, resulting in a larger, uniquely coloured key. This results in a chimerical mish-mash of the spirits, possessing all of their magic with enhanced speed, strength, and durability—however, obviously, as a severe drawback, the resulting spirit won't be too happy with the summoner, thanks to forcibly jumbling their original forms together without a care in the world. As a side note, it is impossible to merge Golden Celestial Spirits belonging to the Twelve Zodiac—as they are composed of purer energy that is impossible to break down, and in addition to this, it is said that the Golden Celestial Spirit Gate Keys are almost indestructible.
 * Urano Metria (, Urano Metoria lit. Ultimate Magic of the Stars): Urano Metria is an uncategorized spell that enables the user to bring down the power of the eighty-eight constellations upon their enemies. Urano Metria is an exceedingly powerful uncategorized spell; said to be on a similar level to that of Abyss Break by some people. While it is technically uncategorized, some theorize it to have something to do with Heavenly Body Magic due to the Runes of both being rather similar, or Celestial Spirit Magic; as the only people who have cast the spell are Celestial Spirit Magicians. It is a "power that unleashes the might of the constellations in the skies" upon the user's enemies; a power that is capable of razing most enemies, turning them into naught but ash before the might of this spell. In any case, when performing Urano Metria, the user focuses their magical power, synchronizing their spirit with the Eighty-Eight Stars of the Heaven (全天８８星, Zenten Hachjūhassei), also known as the eighty-eight constellations (八十八星座, Hachijūhachi Seiza) suspended within the skies- each constellation, of course, represents a single Celestial Spirit, both of the silver tier and the golden tier. Once this has been done, the user recites the incantation, "Survey the Heavens, Open the Heavens...All the stars, far and wide...Show me thy appearance...With such shine. Oh Tetrabiblos... I am the ruler of the stars...Aspect become complete... Open thy malevolent gate. Oh eighty-eight stars of the heaven...Shine! Urano Metria!" (天を測り天を開きあまねく全ての星々その輝きをもって我に姿を示せテトラビブロスよ我は星々の支配者アスペクトは完全なり荒ぶる門を開放せよ全天８８星光る! ウラノ・メトリア, Ten wo hakari ten wo hiraki, Amaneku subete no hoshiboshi, Sono kagayaki wo motte, Ware ni sugata wo shimese. Tetorabiburosu yo, Ware wa hoshiboshi no shihaisha, Asupekuto wa kanzen nari, Araburu mon wo kaihōseyo. Zenten hachijūhassei...Hikaru! Urano Metoria!); this results in the eighty-eight constellations bestowing their power upon the magician- the magician aims at their unfortunate targets, as the visage of countless star-like lights make their appearance within the vicinity, followed by a shroud of darkness blanketing the area. These stars gather and converge all sorts of energies upon their forms before each star detonates in a rather spectacular manner, catching the user's target(s) in the blast range no matter what they do to evade- as each star will follow the target(s) to the ends of the earth like a heat-seeking missile, ensuring that the magical energy spent is not in vain. Upon contact with the enemy, the explosion of all eighty-eight stars released in the form of a tremendous attack provokes the obliteration of the enemy from the inside out in a very violent manner, more often than not propelling the victim into the air or anything in the vicinity by the sheer force of the blast. The force of the blast is enough to pulverize any magical weapons and armour, as well as eradicate any magical auras. One thing to note is that this move is similar to Abyss Break in that it is a compression of multiple "aspects" of a certain magic released in the form of an almighty attack, although Abyss Break does not leave the user in a exhausted state; as contrast to Urano Metria. To the on-looker and also the victim the move would appear as if a myriad of stars came crashing into them provoking a massive galactic explosion with visuals giving the indication of a second Big Bang occurring, all converging upon the unlucky target. Urano Metria packs enough strength to defeat almost any demon; including an Etherious.
 *  ( Gottofurīto lit. Twelve Gold Spirits, Immediate Killing By Heaven's Blade): Gottfried is a technically uncategorized spell which is commonly associated with Celestial Spirit Magic, enabling the wielder to launch an overwhelmingly powerful beam towards their opponent. As the kanji would indicate, Gottfried is only available to a Celestial Spirit Magic user who had collected all twelve of the Gold Zodiac Celestial Spirit Keys. When using the spell, the user takes out all of their Gold Zodiac Celestial Spirit Keys, levitating them in a circular pattern around their body, as they gather their magical energy within their body and spread it out through the tips of their fingers, allowing the user to assort them in a barrier-esque pattern which places all of them in twelve directions, erecting a ritual shrine with the user as a medium. This allows the Gold Key Celestial Spirits to send their respective magics out and merge with the user momentarily, granting them amazing power as celestial energies gather and converge upon their person. Beginning to chant a lengthy incantation, Gottfried transforms the user's magical energy and adds it onto the gathered celestial energy, as the Twelve Gold Spirits converge their energy above the user; whilst chanting, an aura will encase the casters, which will surge upwards, and stars will slowly fill up the heavens. Once enough energy has been gathered, the user and the Twelve Zodiac Spirits manifest a Celestial Summon Gate in front of the user which points towards the foe—it is a glyph of celestial energy that draws the foe in, damaging the foe as the gate slowly opens. All of a sudden, from the gate, a single, powerful beam of celestial energy which is shaped somewhat like the blade of a sword is launched forward at incomprehensible speeds; after a certain distance, the blade splits into any amount of smaller beams to cover more ground, and together with the stars shining brighter which swirl around the target, deals incredible damage. When it impacts, it is capable of causing a huge explosion, which is enough create an enormous crater in the surroundings. However, the spell will inflict pain to the users.

Celestial Spirit Gate Keys
