Shizune, a Junior High school student, suffers from insomnia as a result of her naturally pessimistic nature and also due to the struggle of adjusting to life at her new school. For some reason, the dakimakura she bought in the hopes of getting a good nights sleep somehow gained a mind of its own, took the form of a young girl, and began to take care of and look after her!? A 1000% healing "midnight story" drawn by newcomer Itsumi with a gentle touch and light-hearted humour!
