The Non-Human in Room 203

A first-year high school student, Miyakawa Moeka, who can see ghosts and yokai, finds herself living alone in room 203 of Hachiman Dormitory for certain reasons! In that room, there is an oni with a slender build, black hair and eyes, and horns on his forehead. However, due to a certain incident, Moeka had decided never to get involved with yokai again, so she pretends not to see the oni. The oni, wanting her to notice his existence, keeps pestering her, while Moeka uses her avoidance skills and various methods to evade him. A back-and-forth battle ensues between them. What will become of this everyday romantic comedy between a human and a non-human living under the same roof!
