Aiki? I liked it better when it was called Slut Girl.
I like Aiki a great deal if only because for ONCE, in an Isutoshi manga, the main character isn't a depraved, submissive midget.
Yeah he's the classic invincibly gifted martial artist, that loves to dick around, but is always serious and of course always lands the babe.
You don't see many of those that are this promiscuous, though.
