Devil Slayer Magic (滅悪魔法 Metsuaku Mahō) is a Caster-Type Ancient Spell and Lost Magic[1] used by Devil Slayers.

Description[]

Devil Slayer Magic effects

The effects of learning Devil Slayer Magic too quickly

It is a form of Ancient Spell[1] that allows its users to use a specific element to slay Demons.[2] It also lets the user eat their respective element to replenish strength and become immune to its effects like other types of Slayers,[3] even if it is reflected back at them. Likewise, Devil Slayers are unable to replenish from the element they themselves generate.[4]

This Magic also allows its users to obtain information about a Demon by just observing it for a second,[5] this includes abilities such as Curses and Curse Magic.[6] As a function of being an exorcist, Devil Slayers have the ability to kill and/or exorcise demonic power by exerting their Magic Power upon the target, in other words using the "demon" side of their Magic, given it being the true purpose of the Magic,[7] this Magic is just as effective against Mages who utilise any form of demonic power.[8]

Gray's Demonization

A notable drawback from excessive use of Demon Slayer Magic is turning the user into an actual Demon, a process known as Demonization. Causing them to "demonize" and becoming afflicted with black markings that spread across their entire body, covering up to nearly half of the user as well as changing the color of the eye on the afflicted side of their body at it's peak.[9] The extant of this allows them to become immune (to a limited degree) to the effects of Curses (including the "Ultimate Curse" Memento Mori, which is supposed to completely annihilate whatever it touches.[9])

It has also been suggested that Devil Slayer Magic is a very fickle Magic, and that learning it too quickly and making use of its properties in rapid succession can have adverse effects on the user,[10] said that the souls of those who hunt Demons start to become "tainted", leading the users of this Magic to progressively lose their sanity, of which can incite them to make irrational decisions.[11][12] Although those who master this Magic are able to summon these markings at will to some degree with medical assistance.[13] This transformation also grants the user enhanced physical speed and strength.[14]
