Amako is a young girl who has a great love of sweets. Due to her father’s job, she had to move many times during her childhood, which prevented her from making close friends. Now she’s 15 and starting high school, and it looks like she’ll finally be able to have a normal school life! She intends to join the tea ceremony club, but it’s going to be abolished this year, due to the lack of members.

Hatate Sota is a high school boy who has an ability to visualize “flags” for future events such as “death flag,” “friendship flag,” and “romance flag.” Despite the flag-viewing ability, he avoids making friends with others due to a trauma he experienced in a ship submergence accident. Four beautiful girls get interested in his strange way of living, and they begin to live with him at the school dorm by force.

At Yamaboshi High, joining a school club is required, so when Himeko, Iori, Taichi, Yoshifumi and Yui couldn’t find a suitable choice, they decided to create their own: the School Culture Club! Together, they pass the days meeting and coming up with topics for the group’s newspaper – that is, until one day, Yoshifumi and Yui proclaim that they switched bodies last night! Soon after, all five members of the gang find themselves inadvertently swapping at random, with no end in sight. What, or who, caused this supernatural phenomenon?
