Kibikino-san is a young writer of historical fiction whom Oono Fumi becomes a housekeeper for. In the beginning when they first meet, he comes off as rude and fouled mouthed; however, later on when he finds out Fumi's reasoning for becoming a housekeeper, he seems to have a change of attitude. To make her more comfortable, he gives up his bedroom to her instead of making her stay in a small space in the apartment.

Fumi notices he is very passionate and dedicated to his writing. He also seems to constantly lack sleep and does not eat much while working. Much of Kibikino-san's background is unknown.
