1Kumakichi, alongside the werewolf sisters, has fought back all the humans who want to tear apart their happy family so far, but he now finds himself in a life-and-death battle with Guillaume, the half-Lios commander of the Monster Subjugation Unit. Both Kumakichi and Guillaume are covered in wounds, trading blow after powerful blow, and it won't be long before only one of them is left standing. Polar bear versus lion--it's the greatest grudge match another world has ever seen!
