Plot:
Tokyo Metropolitan Koudou Ikusei High School is a dream school that boasts a 100% admission rate and employment rate, and pays the equivalent of 100,000 yen per month. However, it is a school that only treats students with excellent grades well. In the third semester, Ayanokouji and his friends, who were promoted from Class D to Class C, went to the forest school. There, a special exam called "mixed training" was implemented, which was jointly conducted by all grades. As its name suggests, it is an exam in which students are separated by gender and must form a mixed group of students from multiple classes, and the group is scored as a unit. If you don't cooperate with students from other classes who have always been your enemies, you can't get high scores, and most importantly, someone in the group who doesn't reach the score line will drop out. The turbulent third semester is about to begin!
