Sora, a naive demon who had fled his home, stumbled upon the red light district, unaware of the new world he was entering. While loitering around, he got robbed and caught the attention of Eriru, the owner of a brothel who mistook him for a potential employee.
However, when Eriru approached Sora with a divisive question - whether he was a top or a bottom - the young demon was clueless about the meaning of the interrogation. Unbeknownst to him, Sora would spend numerous days drowning in debt while indulging in the pleasures of his new life in the prostitution paradise.
