Fire Spirit Slayer Magic

Fire Spirit Slayer Magic (火の滅霊魔法, Ka no Metsurei Mahō) is a Caster Magic, Lost Magic, obviously a Slayer Magic, and last, but not least, a Spirit Slayer Magic which is focused upon the transformation of the physiology of the caster's body into a spirit, an extremely powerful type of legendary creature that's classified non-corporeal substance contrasted with the material body; this includes those brought into the physical realm through the power of other magicians that can be categorized as belonging to the definition of Spirit Summoning Magic and are of an ethereal composition, but also encompasses a wide variety of terms, including ghosts and sprites, all attuned to this particular element, resulting in Fire Spirit Slayer Magic revolving around the generation, manipulation, and consumption/absorption of the element known as fire, which is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products as well as heat itself, which is energy that spontaneously passes between a system and its surroundings in some way other than through work or the transfer of matter in addition to the flames of hell that appears as a place of after-death destruction of the wicked. Indeed, Fire Spirit Slayer Magic doesn't only manipulate anything that's classified as related to the fire and the flames, but it encompasses the "concept", which are a generalization or abstraction from experience or the result of a transformation of existing ideas, the concept being instantiated by all of its actual or potential instances, whether these are things in the real world or other ideas that's known as burning, allowing Fire Spirit Slayer Magic to transcend most, if not all other pyrokinetic-type magics, also encompassing the entire concept of "red".

Description
In order to learn the power of Fire Spirit Slayer Magic in the first place, the beginning stages of obtaining its power takes place in a similar manner to a wielder of First Generation Dragon Slayer Magic; being taught by a spirit itself; of course, it doesn't matter what kind of spirit it is, as long as it can be classified as "an incorporeal body with an existence composed entirely out of energy" as per most forms of spirits. A willing user can learn Spirit Slayer Magic from almost any type of spirit, as long as the spirit in question has the methods in order to teach the magician; though "Spirit Kings"; leaders of a spirit race cannot teach a magician, as if they were to attempt to teach a human their magic, they would be unable to accept the force of their magic - however, some exceedingly rare exceptions exist to this. Once a hopeful wielder of this incredible power has decided what spirit to have them teach this magic, the caster must forge a contract with spirits of any type, even ghouls hailed as Summon Spirits which are located within the world of —usually one per town. These beings are part of a set created by the 'higher spirits' for the sole purpose of keeping order within Earth Land. First, the foremost requirement is to locate a spirit. Finding one isn't a walk in the park, that's for sure- the user must be knowledgeable in its habitat, its favorite kind of food, and what it wishes to make out of the contract. From here, the spirit and the caster work out a suitable deal with the target commonly asking for their heart's desire and the user asking for something important to the target in return; but once the deal has been completed, the spirit expels their supernatural energies outwards, engulfing the target in their malefic supernatural powers which seep into the target's body, reaching their soul itself in a ritualistic process. From here, the spirit utilizes their mastery over the arcane and the supernatural particles that are strewn about through this world of whimsy and wonder, engulfing the hopeful wielder with their arcane energies as they seep inside of the target's body, with the spirit reaching inside the humanoid's soul, searching for that otherworldly organ referred to as a Magic Origin and from there, making a few changes here and there as to alter the process of how the Magic Origin functions and its properties, therefore transmogrifying their Magic Origin into a strange hybrid between that of a spirit's Magic Origin and a humanoid Magic Origin, possessing the traits of the former but the arcane storage capacity of the latter, effectively causing their body to be bestowed with the magical powers of a Spirit - otherwise known as Spirit Slayer Magic. Continuing with this process, this magical power acts alongside the energy of the body in order to catalyze a variety of bodily processes, therefore allowing the morphing of their physiology to a point where the individual has adopted some physical traits, a myriad of abilities also shared with their teacher, as well as the element from the said spirit, which can be conjured from the magician's body for countless purposes; upon teaching the magician their form of Spirit Slayer Magic, the spirit enters the caster's soul in a manner not dissimilar to the Dragon Soul Seal and engraves their powers within the wielder, constantly boosting Spirit Slayer Magic to a level akin to Primal Dragon Mode. As one may notice, Spirit Slayer's mechanics are extremely similar to that of any other Slayer Magic; however, there's more than meets the eye.

However, as well as what's detailed below, what sets Spirit Slayer Magic apart from other forms of Slayer Magic, including Dragon Slayer Magic, God Slayer Magic, Devil Slayer Magic, and Phoenix Slayer Magic is that the installment process of the user's spirit teacher's magical energies and subsequent change in their physiology results in an exceedingly beneficial mutation alongside the regular boosts in bodily properties a wielder of Slayer Magic receives during the learning process. Indeed, the Magic Origin of a Spirit Slayer becomes transmogrified into what can be semi-accurately described as a "pendulum", the caster's Magic Origin serving as the weight while their thoughts and feelings fulfilling the purpose of a pivot. Referred to as the Pendulum of Souls (振子の魂, Furiko no Damashī) once Spirit Slayer Magic has finally become integrated within the caster's existence, the user's Magic Origin, just like a pendulum when it's displaced sideways from its resting position is subject to a restoring force due to gravity that accelerates it back towards the resting position, seemingly bounds around the caster's body while dramatically enhancing their particle draw far beyond the likes of fellow Slayer Magics, swinging back and forth, this results in a greater output of magical energy at the wielder's beck and call, effectively enabling the wielder of Spirit Slayer Magic to manifest a multitude of high-level spells and power-ups at once. While this does result in the wielder of Spirit Slayer Magic having to charge their power up to enable this effect by invoking Trance, the ability to manifest countless varying-levelled spells and power-ups all at once still proves to be a powerful force in a battle, especially since this effect extends to other magics the caster possesses, and thus makes extremely powerful abilities such as Abyss Break and far easier to pull off and can be unleashed in quick succession without any rest in-between their casting sequences, whereas even the most skilled of magicians would be exhausted from utilizing their power. Because their Magic Origin is swinging back and forth like a pendulum, as magic is fuelled by the thoughts and feelings of the wielder, the wielder of Spirit Slayer Magic is known to have their emotions affect their elemental power on a much greater level and scope than ordinary forms of Slayer Magic, continuously surpassing itself as the user fights and progresses in power, adapting and evolving through a wielder's emotions, gaining certain abilities and qualities as the caster becomes stronger. Tachyon Spirit Slayer Magic is said to bring the potency of this pendulum of souls to its utmost limit, surpassing all alternative versions of Spirit Slayer Magic easily as the speeds that the pendulum known as the caster's Magic Origin swings back and forth at utterly defy the laws of casualty, allowing for an even greater particle draw and output than normal Spirit Slayer Magics. As flame is one of the most common elements of all, Fire Spirit Slayer Magic seems to continuously absorb traces of oxygen and anything that could be considered to be able to produce fire in order to allow the caster a quicker casting time and boosted strength.

When inducing the activation process for Fire Spirit Slayer Magic and thereby performing the signature flame manipulation of the magic, the caster utilizes an activation sequence not dissimilar from fire-element Slayer Magics such as Fire Dragon Slayer Magic,, , and of course, Fire Devil Slayer Magic, as they focus the voluminous quantity of arcane energies that dwell within the supernatural organ known as their Magic Origin intently, before using naught but a singular mental command in order to release these energies outwards into the immediate vicinity, from here inducing the usual fusion of eternano that's ambient within the atmosphere and said arcane energies while forcing a certain level of domination over these energies as they take the concept of magic equaling the feelings of the magician to the very next level – harnessing their willpower as a perfect catalyst, the wielder of Fire Spirit Slayer Magic, using their burning ambition and blazing blood that courses through their veins excites the movements of the eternano, thus increasing their thermal energy, which is the internal energy present in a system due to its temperature, and kinetic energy, which is effectively the energy that is possessed by any object while in motion and the necessary work that is required for anything at all with a given mass to move, to the point that the particles strewn about throughout the vicinity spontaneously ignite, thereby manifesting a noticeable quantity of flames that burn exuberantly, flickering wildly and continuously. Of course, no matter the activation method for Fire Spirit Slayer Magic, the end result is always the same in that it grants the caster the ability to manipulate, modify, consume, and generate from their body the element of fire, which is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products in addition to heat and hellfire. Effectively, this grants the user of Fire Spirit Slayer Magic the ability to call upon the assets of a spirit even if their bodily structure isn't one-hundred-percent the same as the beings from which this magic originated, the caster is capable of inducing a metamorphosis of their body structure as to take upon traits of a spirit instantaneously which is done in conjunction with the activation sequence as mentioned above, bestowing upon the user of Fire Spirit Slayer Magic the lungs and enhanced vocal folds of a spirit that are capable of spewing heat waves to simulate the effects of prolonged periods of excessively hot weather as well as fireballs to blast the enemy, a corporal body and defenses which are naturally laced with high quantities of flame in order to withstand high temperatures that come about due to a variety of factors as well as protection against anything considered to have an affinity for flame, and last but not least, fierce limbs, whether prehensile or not which are enshrouded flame as to specifically attune them to dealing incredible amounts of damage, allowing them to melt through all kinds of alloys, whether they be manmade or natural with relative ease, overall incorporating the element of flame into their body – all of this combined, results in the wielder of Fire Spirit Slayer Magic transforming their entire existence into that of a make-shift weapon whose ownership is unique to them and them alone, wielding the element of flame that was harnessed by the spirit that taught them and passed down to them alongside the natural physical superiority of a spirit in combat, utilizing offensive ability, stamina, and vitality, to transmogrify themselves into the greatest weapon of all, thus dramatically increasing the damage inflicted upon anything that they come into contact with using the sheer force of their strikes in all ranges; however, as one may have suspected, like a majority of Slayer Magics, close-combat is where Spirit Slayer Magic usually shines thanks to the physical might of a spirit; as the magic massively bolsters the power of their unarmed blows with the user unleashing countless vicious strikes which are empowered with wakes of destructive heat and high-intensity flames which wreak havoc on anything and everything that they come into contact with through the transference of heat from one source to another as well as scorching anything they so much as glance past. More or less, as mentioned before, this grants the wielder of Fire Spirit Slayer Magic the ability to manipulate, modify, consume, and generate from their body flames to their fullest extent- they have absolute dominance over all forms of fire and everything related to and dwelling within it – but going onto the opening paragraph, this also includes heat and anything else, even if it is a small byproduct of flame, granting them dominance over the concept of "red".

Basic Spells

 * Fire Spirit's Harangue (火霊の説教, Karei no Sekkyō): Fire Spirit's Harangue is the a variant of the Spirit's Harangue spell which is the Spirit Slayer's equivalent to the Dragon Slayer's Roar and God Slayer's Bellow spells, attuned to the element of fire as per the nature of this magic, and is as such considered a basic Fire Spirit Slayer Magic spell that involves the wielder of Fire Spirit Slayer Magic firstly inhaling as to gather fire within their mouth before quickly releasing said fire in the direction of their enemy in the form of an enormous fireball with explosive properties.

Trance

 * BurningRedPer.jpgTrance: Burning Red (, Toransu: Baningu Reddo lit. Spiritual Awakening State: The Refined Flame Colossus Defender): Trance, formerly referred to as Geist Charge (, Gaisuto Chāji lit. Spiritual Awakening State), is an uncategorized Spirit Slayer Magic spell that's an Magic-amplification technique and equivalent to Dragon Slayer Magic's Drive; Trance brings out the true power of their capabilities as a user of Spirit Slayer Magic, excluding the power boost granted by Spirit Force, yet, at the same time, seemingly enhancing the user's physical prowess to a rather extreme degree. Indeed, as there's only one generation of Spirit Slayer Magic so to speak, unlike its draconic equivalent, Drive, which is exclusive to Third-Generation Dragon Slayers, due to Spirit Slayer Magic being incompatible with Lacrima, the magic crystalline substance found on both and  which can be used to implant various forms of magic, Trance is known to be capable of being harnessed by any user of Spirit Slayer Magic as long as they possess the power necessary to induce its effects and the knowledge of how to do so. The iteration of Trance that comes automatically equipped within Fire Spirit Slayer Magic is known as Trance: Burning Red. When invoking the power of Trance: Burning Red, the caster focuses the voluminous quantity of arcane energies that dwell within the supernatural organ known as their Magic Origin intently, before using naught but a singular mental command in order to release these energies outwards into the immediate vicinity, from here inducing the usual fusion of eternano that's ambient within the atmosphere and said arcane energies while forcing a certain level of domination over these energies as they take the concept of magic equaling the feelings of the magician to the very next level – harnessing their willpower as a perfect catalyst, the wielder of Fire Spirit Slayer Magic, using their burning ambition and blazing blood that courses through their veins excites the movements of the eternano, thus increasing their thermal energy, which is the internal energy present in a system due to its temperature, and kinetic energy, which is effectively the energy that is possessed by any object while in motion and the necessary work that is required for anything at all with a given mass to move, to the point that the particles strewn about throughout the vicinity spontaneously ignite, thereby manifesting a noticeable quantity of flames that burn exuberantly, flickering wildly and continuously. From here, after obtaining enough magical power to transform, the wielder of Fire Spirit Slayer Magic focuses their magical power, establishing a connection with their spirit teacher, no matter the distance between the two and the dimensional differences before the wielder of Fire Spirit Slayer Magic summons the spirit whom taught them to the current dimension using their spiritual link. Once this is done, the user utilizes their spiritually-attuned Magic Origin as a medium for their spirit teacher – Burning Red is a Manifesto-Type (, Manifesuto Taipu lit. Ghost Puppet Type); a Trance in the form of the user's elemental power that is manifested in a physical form that acts on its own; because of this, the user does not need to lift a finger to strike; their flaming energies will do it for them. While the Manifesto-Type resembles any sort of summoning magic, it's an extension of the user rather than a separate entity; the Manifesto-Type hovers around the Spirit Slayer in a similar manner to that of a wraith; hovering behind and above the user while usually being invisible to those unaware of them. The Manifesto-Type can attack in tandem with the user, bolstering their strength significantly while working as a medium to cast higher-powered spells. Burning Red is the first member of the Grimoire Five (, Gurimoa Faibu lit. Five Great Elemental Embodiment Colossus Defenders), which are, well, as the designation would indicate, Manifesto-Type Trances whom are an embodiment of the five fundamental elements of nature. They are known to manifest only in exceptionally powerful and determined individuals, with, as their sub-name would indicate, there only being five in existence- once a previous owner dies, their Trance will reincarnate in somebody else. The power of the group is unmatched by any other Trance type and even summon spirit, except for spirit king-class beings. They have the ability to consume their element to further enhance their own power; this can be from any source, such as Lost Magic and Slayer Magic. Burning Red takes upon the form of a large demonic humanoid which is, well, burning red. Its large arms also function as black claws, and its body glows with a bright yellow light which constantly seeps out from its gigantic body. Its feet are covered in a hardened, black crust of lava, and its head has two, black horns extending from the sides, along with glowing emerald eyes. Burning Red protects the user, like a guardian, sometimes using their powers without direct orders in order to protect the user, and by extension, themselves. As Burning Red is part of the user, damage is reflected between the two. In most circumstances, if the spirit's leg is sliced off, the user will lose their leg as well; essentially making it a larger target to a sufficiently stronger opponent. The further Burning Red is from its user, the weaker it becomes, with most only being capable of acting within three meters. As Burning Red is just an image created by the user's flames, the user is able to shrink them, mostly to enter the body of the opponent and attack its inside. Staying small, however, is very hard and is incredibly taxing on their magical energy. Burning Red copies the movements of the user to devastating effect, allowing it to deal out colossal amounts of damage; and in addition to its overwhelming strength, despite its enormous size, it is also deceptively fast, as it instantly copies all of the user's movements. Burning Red, as the name would ever so subtly indicate, has the ability to generate massive amounts of flame effortlessly; these flames are said to be a special type, referred to as the Cursed Fires (呪いの炎, Noroi no Honō), which suck away life energy; upon contact with normal beings, the flames suddenly become alive, so to speak, and latch onto them, sucking up their energy which allows the fire to intensify, draining the environment of life while burning it to ashes.

Advanced Spells
Of course, like every other Slayer Magic, a Spirit Slayer has access to "finishing moves", the advanced spells of a Spirit Slayer are known as Spirit Slayer's Secret Arts (滅霊奥義, Metsurei Ōgi); which are generally much more powerful than basic techniques. All Spirit Slayer's Secret Arts boast overwhelming power, being dubbed the "ultimate spear" of a Spirit Slayer; however, they usually cost a large amount of magical energy to properly cast. However, in addition to these "finishing moves", when in any powered up state, a Spirit Slayer can harness Oversoul Arts (, Ōbasōru Āto lit. Spirit Slayer's Revised Secret Arts), which are further enhanced to the point that it is said that even the weakest spell can smash through anything unfortunate enough to be in its path.
 * Mars' Passion: Helltide Inferno (, Marusuzu Passhon: Herutaido Inferuno lit. Raging Flame Spirit: Spirit King's Conflagration Pillar Array): Mars' Passion: Helltide Inferno is an advanced Fire Spirit Slayer Magic spell which is one of the Spirit Slayer's Secret Arts, the strongest spells of a Spirit Slayer – in the case of Mars' Passion: Helltide Inferno, it involves the wielder of Fire Spirit Slayer Magic focuses the flames dwelling upon their hands before outlining a circle around anywhere they deem to be a target, trapping the enemy while exposing them to the heat generated by the fires swirling around the target.
