Ikazuchi Akatsuki

Abilities
Branch of Sin: Ikaduchi is a Forgery, so he has the ability to freely control his blood out of his body.

Branch of Sin: Decimating Frenzy (乱离乱身, Rari Ranshin): Decimating Frenzy allows him to create hook-like tentacles that inject himself with blood. This causes his arms or legs to enlarge and become extremely muscular, like some kind of doping and gain superhuman strength. So Ikaduchi doesn't use his Branch as a main weapon, but rather his enlarged body.
