キリングバイツ

Unremarkable college student Yuuya Nomoto is dragged into a scheme by classmates to abduct a girl named Hitomi Uzaki, then watches her tear apart a lion-like fighter at an abandoned facility. Hitomi is a Brute, a human spliced with the traits of a honey badger, fearless against far larger foes. Her guardian Reiichi Shido forces Yuuya to house her and bankroll her matches in the Killing Bites, underground death bouts staged between Brutes by rival zaibatsu.
