Blank Slate, Volume 1 - Aya Kanno

What does it take to find your true inner self? Zen's memory has been wiped, and he can't remember if he's a killer or a hero. And a lot of people will do anything they can to keep it that way.
Zen's unearthly charm attracts a veritable rogues' gallery. A bounty hunter becomes obsessed enough to become his new partner, while the daughter of General treats him like some sort of guru. But when he meets a mysterious doctor who may know him from the past, Zen learns that the secret of his lost memory is definitely more sinister than saintly.
