The Boy and the Beast

The story

When Kyuuta, a young orphan living on the streets of Shibuya, stumbles into a fantastic world of beasts, he’s taken in by Kumatetsu, a gruff, rough-around-the-edges warrior beast who’s been searching for the perfect apprentice. Despite their constant bickering, Kyuuta and Kumatetsu begin training together and slowly form a bond as surrogate father and son. But when a deep darkness threatens to throw the human and beast worlds into chaos, the strong bond between this unlikely pair will be put to the ultimate test—a final showdown that will only be won if the two can finally work together using all of their combined strength and courage.
