The Beast Claw

The Kifuuken dojo has kept a centuries-old secret: Shokujinki, human-like creatures that turn into monstrous beasts with claws, have coexisted with humans, feeding on them to survive. The Kifuuken's mission to cut off the Shokujinki's arms has prevented their domination. At the dojo, Toshihiko Momota, the leader's son, develops a complicated relationship with Yuka Kamitsuki, unaware she's a Shokujinki, and that he's duty-bound to kill her.
