[quote=Indra's Notes 101: Devil Slayer Magic]

[i]Side Effects[/i]
A lost magic that is designed to destroy demons. Compare to its relative slayer magic; God and Dragon Slayer, it's really fickle because the longer it is used, the Devil Slayer gradually succumbs to insanity which is a long lasting side effect. Their minds gradually distort even if a demon is killed and absorbed a curse from it. Insanity Effects that of the Curse of Contradiction; Paranoia to some degree because of the magic's program to kill demons and until one day, they turn into full blown demons. 

[i]Strengths [/i]
All Slayer Magics have the power to kill what they have to slay. The Devil Slayer magic is this as well but way different because with the  [u]Akugan[/u](Devil's Eye) allows its users to obtain information about a Demon by just observing it for a second. The eyes of the Devil Slayer will be in a different color that respectively represents their element. With the Devil's Eye they are able to see through curse related spells. 

[i]Instantaneous Flashes[/i]
A Devil Slayer who has mastered their magic can perform feats that surpasses their own element's weaknesses. This can only be achieved through training and this very feat only applies to high level spells. A Devil Slayer Secret Art totally qualifies for this.

[i]Weaknesses [/i]
The sanity slippage is one of them but for all Slayers; they are designed for raw power. A Slayer is doomed to not have a manipulation shape on the magic itself. Even if this weakness can be bypassed through molding magic, it does not warrant perfect control due to the nature of Devil Slayer Magic.[/quote]
