The Host Mafia

Rated M for violence and language. Kaoru us a member of the most powerful and strongest Mafia's around. But what happens when he finds Haruhi abused and neglected, he takes her in of course. Now with a new member there are bound to be a few twists and turns along the way, but who is it that is after Haruhi? Suck a summary people, sorry. RxR please.
