Imomushi

Imomushi is a carefree girl, who's something of a "big sister" to a few people in the organization. She is actually always serious in whatever she does. She usually refuses to kill people who aren't her targets, but is willing to do so if they have a bounty on their heads. In the manner of a carnivorous caterpillar's way of attacking, Imomushi's shoes are able to nail her to the ground so she can swing back and forth to headbutt or punch her enemies. She calls this technique the Anchor Bolt Caterpillar Cannon (headbutt)/Bullet (punch). Her strength is comparable to Kabutomushi's, such that even as a child she was able to pound heads into paste when enraged. She is also known as the "Adaptive Mutant" for her near immunity to poison and chemicals in general for reasons even she doesn't really understand. Under the name Miki Inou, Imomushi used to live in an orphanage with her sister Mika. Miki was a tough delinquent and very protective of her sister, but found out the staff was heavily abusing the poor girl in exchange for not sending Miki away due to her behavior. Miki killed them in a rage, but was unable to save Mika from being choked to death. The next thing she knew, Suzumebachi took her into the Organization as one of many recruit children and held her guilty for everything that had happened. She was then trained by the assassin Kagimushi and learned to keep her emotions in check so even as a killer-for-hire she'd become the kind of mature person Mika wanted her to be.
