From Seven Seas:

He was the world's greatest ninja... or so they tell him.

The Shadow Clan is a US-based ninja clan hidden in small-town middle America. Their newest grandmaster, the 18-year-old "Inazuma," was destined for greatness. But on an important mission, he was ambushed and fell to his death. Or so everyone thinks. Because oddly enough, five years later, he reemerges in Hollywood as a struggling actor.

The new Grandmaster of the clan dispatches his beautiful daughter, Anna Pearson, a full-fledged ninja herself, to Los Angeles to track down their lost ninja. But Anna has never been outside the clan, and she’s in for quite a shock when her traditional ninja values collide with LA life, not to mention when she meets the deadbeat actor in person, with no memory of his former life as a ninja.
