Shintaisou (Kari)

Toguro Nikusuke, 35, is a gym teacher at Shirakawa Academy. It was on his payday last month that he received a letter from the Dark Rhythmic Gymnastics Association. One month later, he was waiting for it, and now he had that “secret plan” in his hands. But the contents of the plan were to teach Rhythmic Gymnastics to girls and humiliate them. Naturally, it was unfeasible. It was insane. However, the stupid Nekisuke took the plan to heart. It's okay if only he was that stupid. But things became even more foolish. Tomomi Shirakawa, the granddaughter of the chairman of the board of directors, finds out about the plan. Of all the people who should not know about the plan, Tomomi was the worst case. Tomomi has a bad temper. She is sure to tell the board chairman. If anyone found out about this dirty plan, he would be fired from the school and beaten up. Nekisuke was terrified. But the answer he got from Tomomi was surprising. "There is a girl in the rhythmic gymnastics club that I want you to mess up. If you help me...” Now, Tomomi, who has tremendous power in the school, and Nikusuke, who has tremendous force of will, have teamed up. And with the Shirakawa Academy Rhythmic Gymnastics Club as the stage. The “Dark Rhythmic Gymnastics” was about to become a reality.
