Ninja Assassin (2009)

Raizo, one of the best assassins in the world turns his back on his own clan after they murder his one true love

Orphaned as a child and raised by the shadowy Ozunu Clan, Raizo becomes one of the deadliest assassins in the world. Years of brutal ninja training harden him into an emotionless, lethal killer, loyal only to the clan that raised him, and to Kiriko, his childhood companion and fellow orphan. But when Kiriko attempts to escape the clan and is brutally executed in front of him, Raizo is devastated. Her death shatters his loyalty towards the clan, and forces him down a ruthless path of vengeance.
