Ryuka

A simple-minded and slow-witted demon, he is the one who captured Kurumi, seemingly interested in only his own gain. Despite his initial attempts to sell her, he comes to pity her and tries to guide her back to the human world. He takes her into his home when these attempts fail, but his caretaking efforts only yield more difficulties, as he treats her like a pet and denies her all independence, assuming her to be incapable of performing even the most basic of actions.
