Weakness compels strength. Betrayal begets blood. This is the law of the nine ninja clans. Tora the adopted sister of Mika has come to live with Mika after the trial against the man who had killed their mother and kidnapped Tora ended. The Man, Jose Saldana is now in jail for life and Mika hopes in giving Tora a better life. However, Tora was raised up in the streets and is classified as a "troubled youth" known to get into trouble. Tora is still heavily tied to her gang life. When Raizo returns to Mika in hopes of her helping him fit into the new (normal) world he is attacked by Tora who thinks he is a robber, Raizo almost kills Tora when Mika arrives home. Mika allows Raizo to stay with them as long as he mentors Tora and helps keep her out of trouble. However not one of them takes notice that the other 8 surviving ninja clans are out for Raizo's head due to his great betrayal to the Ozunu Clan. The Clans set free Jose Saldana to help them locate and find Tora whom the Clans know is tied to Raizo.

What if your roommate was an assassin from South Korea? This is an AMBW story ;)

It's 3 years after the destruction of the Ozunu Clan. Mika is now living her regular life, back to working under Ryan and working on cases. But Raizo visits her again, with important news: another group of ninjas are after her. AGAIN. Will Raizo be able to protect Mika as well as he did three years ago or will everything be over for them both?
