The story takes place in Nanamori Junior High School. The tea ceremony club is facing the tragic fate of closing down due to poor popularity. Four girls, Akaza Teru (voiced by Eori Mikami), the cheerful and enthusiastic runaway girl Kyoko Saina (voiced by Yuka Ootsubo), the taciturn but spit-tasting Yui Funami (voiced by Minami Tsuda), and the seemingly cute and harmless but actually very sinister Chiharu Yoshikawa (voiced by Rumi Okubo), occupy the activity classroom of the tea ceremony club and set up an entertainment club. The prologue of the story begins. The existence of the entertainment club has attracted the attention of the student council. The intervention of the mysterious president Matsumoto Risa (voiced by Saori Goto) and the arrogant and insincere vice president Sugiura Ayano (voiced by Saki Fujita) has added a bit of joy to the already lively club life.
