A student council member named Hasumi Ryou discovers a charm on the floor, which leads to a junior high student with poor academic performance appearing in his room. She addresses him as Kami-sama and requests assistance in passing her high school entrance exam. Each day after school, his room inexplicably transforms into hers, yet Ryou chooses to accept the situation, moved by her sincere wish to attend high school.
