Highly nurturing colleges and universities.
A "paradise" surrounded by a three-meter-high wall and completely isolated from the outside world. Personal points equivalent to 100,000 yen are issued every month. The facilities on campus are extremely luxurious and almost 100% of graduates are employed.
But beneath this glamorous appearance, a set of extremely cold rules operates. Class confrontation, point competition, the winner reaches the top of Class A, and the loser falls into the abyss. Every student is clearly priced.
Toru Kanzaki, a freshman in Class D. His grades are mediocre and his physical fitness is average. His only advantage is that he has a keener insight into people's hearts than his peers.
On the first day of school, on the bus. He met a girl who desperately lowered the brim of her hat and hid herself in the corner - Sakura Airi.
He is taciturn and has a thin sense of presence, as if he is deliberately erasing himself from the crowd. But deep in her eyes, Toru Kanzaki saw something very familiar to him: uneasiness about the world and the stubbornness to survive desperately.
At that moment, he reached out to her.
From the truth behind Sudo's fight, to the secret battle in the preferential treatment exam, to the plan for survival on an uninhabited island - special exams carefully designed by the school one after another push Class D to the edge of the cliff again and again.
Conspiracy and calculation, betrayal and alliance.
In this academy where strength is paramount, there are no absolute enemies and no permanent friends.
The only thing that Tohru Kanzaki knew for sure was that he would protect the people worth protecting, and then climb up on his opponent's body.
Starting with Sakura Airi.
Then, he will have more companions.
