[Original work: Puu no Puu Puu Puu/Popular aphrodisiac manga with sales of 20,000 copies! ] I came to a rental apartment exclusively for youkai in a quiet residential area a few months ago to take over from my father who suddenly passed away. There was Yukino, a very fragile and beautiful widow who lost her husband. And in the room where my father was left behind, there was a ring that wasn't supposed to be there, and could only control monsters at will. He was supposed to help Yukino-san's life in poverty, but as his own desires dictated to him, the situation took an unexpected turn.
