From Pink Litchi Scanlations:

Nishikado Taketora is a high schooler with piercings, blond hair, and scary facial features. Even though he only wants to be normal, he keeps getting involved with yankees. Despite of all that, this fierce tiger spots someone that’s totally his type!

After running away from home, Sora, a demon who knows nothing of the world, found himself in the red light district. Eriru, the owner of a brothel, sees him loitering around after he got pickpocketed, and picks him up, mistakenly thinking he wanted to work there.

"So? Are you a top or a bottom?" What waited for Sora, who didn't even know what that meant, was days of debt and pleasure in prostitution paradise.
