Ai wa Kane Nari Love is Money

Synopsis

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. (Source: Kasakura Shuppansha, translated)
