Crimson Blood (Shokan Series #1 w/soundtrack)

Imagine finding out that the man who raised you isn’t actually your father, and that your mother is withholding even more secrets. On top of that you are expected to defend your tribe from horrific hybrids.

This is what Kazai, a rookie protector of the Umi Tribe, is dealing with. All the while, he doesn’t even realize the history of the two greater forces that he finds himself caught between.
