Tokyo Advanced Education High School is a dream school that prides itself on a 100% admission rate and employment rate, and a monthly payment equivalent to 100,000 yen.However, at its core, it is a merit-based school where only some outstanding students receive good treatment.As the third semester approaches, Ayanokouji and others, who were promoted from Class D to Class C, head to the forest school.What is conducted there is a special joint examination for all grades called "mixed training".As its name suggests, it is divided into men and women, and students must form a mixed group of students from multiple classes, and the exam will be graded as a unit.It is impossible to achieve high scores without cooperating with students from other classes who have always competed as enemies, and most importantly, someone in the group who did not reach the score line will drop out.The turbulent third semester is about to begin!
