The absence of any suitable clubs prompts the formation of the Student Cultural Society, or "StuCS," by five pupils at Yamaboshi Academy. Its members span diverse interests; Taichi favors wrestling, Iori is indecisive yet optimistic, Himeko possesses a serene disposition and tech acumen, Yui specializes in karate, and Yoshifumi acts as the class clown. On a particular day, Yui and Yoshifumi encounter an unusual occurrence that sees them switch bodies abruptly. As this supernatural phenomenon repeatedly affects the five companions, they recognize that it is not merely for amusement. The experience demands that they form a closer bond and reveal their vulnerabilities and burdens, which incubates the risk of breaking their friendship and StuCS apart.
