Akakabuto has been causing trouble by attacking and consuming the farmer's cattle and soon starts to attack humans. The hunter, Takeda Gohei starts to hunt the bear together with his wolf Shiro. On a hunt Akakabuto attacks Takeda Gohei and the other hunters causing all of them to die except Takeda Gohei who loses his left ear. Akakabuto and Shiro fight and Takeda Gohei does his best to protect his dog by shooting Akakabuto's right eye out, which also causes the bear a brain damage. Shiro sees no other option than to push Akakabuto and himself down a valley. Akakabuto survived this while Shiro did not.
