Ikazuchi Akatsuki

Ikaduchi Akatsiki was a complete forgery, assigned in the first unit. He seems to be the one responsible for the death of Senji Kiyomasa's allies during the time of when he was a police officer. When Senji found out, Ikaduchi was killed.

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 scorpion tail-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 gains superhuman strength, powerful enough to strengthen his tendons and shatter Senji's normal Crow Claw blade. So Ikaduchi doesn't use his Branch as a main weapon, but rather his enlarged body.

Asōgi (阿僧祗): Idaduchi enlarges his legs to become incredibly muscular, that have enough power to jump several feet in the air.
