Private Tenshou Gakuen is the seventh of ten school districts circled within a 130-meter tall wall with restricted entry and egress aside from officials. The academy is fully autonomous by the government but to strive for independence, the school allows students to engage in club activities after school, which comes with a strangely unique system. Each club is ranked according to its overall accumulated points gathered from various club activities and school events. Points can also be received by winning at the school's periodic Tenshou Gakuen Singing Contest, where many students compete. The members in the clubs work hard to win the contest for their goal.

Second season of One Room.

The new "slapstick" story will depict Komugi-chan and her rivals as they juggle their daily lives as students, idols, and magical girls "with laughter and tears." Komugi Yoshida is a somewhat clumsy second-year middle-school student whose strong point is her spiritedness. She performs as an idol like Kokona Saionji (her classmate and close friend) and Tsubasa Kisaragi (an idol who dresses in male clothing). However, unlike Kokona whose popularity is skyrocketing and Tsubasa with her charisma in male attire, Komugi's only gigs are low-end ones like those at the local shopping district. Still, Komugi has her "dream" as she lives her dual lives as a idol and a middle school girl. One day, a mysterious injured creature named Usa-P appears before Komugi. Komugi gives Usa-P medical treatment, and Usa-P, in consideration of Komugi's kindness, asks if she wants to be a Legendary Girl who can use magical powers. Having become a reluctant Legendary Girl, Komugi battles strange masked figures who suddenly appear! As a newly deemed Magical Nurse, she fights still more waves of masked figures. Meanwhile, a Magical Maid, a Magical Sister, and more also appear to make it a three-way battle!? Can Komugi handle the three roles of middle school girl, idol, and Magical Nurse? And, what lies ahead in these battles and her "dream"...?!

Based on a parody manga of Be-Bop Highschool.
