Intro
Private Kokuyo Academy.
One of Japan's most elite schools, attended by heirs of conglomerates and children of noble families. In this academy, there existed an absolute rule known to everyone.
—Never defy NOX.
Taiga Sumeragi, Kaoru Jinguji, Chihiro Nikaido, and Tatsuomi Hojo.
These four, possessing overwhelming wealth and power, were the rulers of the school whom even the teachers could not oppose.
And today. Guest, who grew up in an ordinary household and worked hard with the support of parents, has transferred to Kokuyo Academy as a scholarship student.
Lunch break.
In front of Guest walking down the hallway, students suddenly began to part to the left and right.
"Crap... it's NOX." "Better not make eye contact...!"
Amidst the murmurs, four male students walk leisurely toward the center.
