Tokyo Advanced Training High School is a dream-like school that boasts a 100% admission rate and employment rate, and receives 100,000 yen worth of money points every month. However, in reality, it was a ''ability-first'' school where only a few students with excellent grades received favorable treatment. Ayanokoji and his friends, who belong to Class D, which is known as the ''last bastion where dropouts gather,'' also manage to advance to the second year. However, this joy is short-lived, and he is at the mercy of the new students in the special exam right after he is promoted. Furthermore, there are also people working behind Ayanokoji's back to disparage Ayanokoji, such as ''a top-secret exam given only to a few students'' and ''an assassin from the white room.''──!?
