Relax, I'm a Ninja

A Clan of ninjas in San Francisco may sound improbable-but as the son of a ninja Master, Tosh Ito knows what lurks in the shadows of his city. Or at least he thought he did.

When a killer with a poisoned blade starts cutting down teens, Tosh enlists Amy Sato-newest ninja recruit, and his best friend's crush-and sets out to uncover the killer's identity. What they find is ninjutsu more evil than they could have ever imagined.

As Amy and Tosh grow closer, they discover their connection unleashes a legendary power that could stop the murders. Problem is, that power may be exactly what the killer is looking for, and wielding it could cost them their souls.

Trust Me, I'm a Ninja

Life hasn’t exactly been rosy since Tosh Ito and Amy Sato rid San Francisco of the Akuma Clan ninjas. They still can’t control their powers, and no one really knows how to train them to be Inyo. Adding to their problems, Amy is distant and depressed and won’t say why.

Before Tosh can figure her out, the Akuma Clan makes a comeback. A gate to the kami realm is opened and strange creatures roam the city, causing chaos. Only Tosh and Amy can stop it, but they don’t know how, and they haven’t got time to learn. The gate is getting bigger, and something dangerous is waiting on the other side. Something hungry for the soul of an Inyo.

Back Off, I'm a Ninja

Tosh and Amy may have managed to keep the demon Akuma in the kami realm, but that hardly spells success. While the living realm is spared, Akuma consumes all kami in his path. Even worse—he’s targeting Tosh and Amy’s ancestors, consuming them and weakening the Inyo all in one shot.

When Akuma’s Clan murders not just ancestors but their living relatives, Tosh and Amy can’t waste time mourning those they’ve lost. They must get stronger. They must defeat Akuma before he siphons all their power and more people die.

Just as they approach their peak strength, Akuma’s dark shaman deals a devastating blow. Weakened and captured by the enemy, Tosh and Amy have run out of options. Unless they can discover a new kind of strength, they must not only sever their connection with each other but lose their souls, and every else’s, to Akuma.
