When five students at Yamaboshi Academy realize there are no clubs where they fit in, they join forces to create the Student Cultural Society, or "StuCS" for short. The group includes: Taichi Yaegashi, a hardcore wrestling fan; Iori Nagase, an indecisive optimist; Himeko Inaba, a calm computer genius; Yui Kiriyama, a petite karate practitioner; and Yoshifumi Aoki, the class clown. One day, Aoki and Yui experience a strange incident when, without warning, they switch bodies for a short period. As this supernatural phenomenon continues to occur randomly among the five friends, they begin to realize it is not just fun and games. Now forced to become closer than ever, they soon uncover each other's hidden secrets and emotional scars, which could end up tearing the StuCS and their friendship apart.
