A boy with a destiny he doesn’t understand.
Ryuichi must learn to master powers he barely understands that he inherited from his mother and protect the gates that she guarded to the other worlds or kami, yôkai and demons who are bent on making mankind suffer will flood the human realm.
No one can be trusted. Not even his own guardian . . . and here he thought puberty was the worst thing to threaten his sanity.
If he’s to survive, he has to figure out who his real allies are, and who wants him dead. He will have to become the Demon Shinobi and learn that sometimes things have to go wrong in order to go right. That in order to overcome evil, sometimes you have to bend the rules and be more than you ever thought you could be and believe in people others tell you not to trust.
