Isekai Shoukan no Shihainin

A young boy was transported to another world and received a unique ability focused on hygiene and health magic. This power is useless in combat but highly valuable in managing a brothel. He has been in charge of the establishment, Papillon’s Somnium, for several years after being entrusted with it by the person who saved his life. The brothel remains open at night, offering its services to customers seeking pleasure and companionship.
