Ouka Academy.
An ultra-elite school where the children of Japan's leading conglomerates and prestigious families gather.
In this academy, there are five individuals whom everyone fears and everyone admires.
Their name is—'MONARCH'.
Ritsu Kujo, Yuma Otori, Leo Sakaki, Miyabi Takamiya, and Emma Kanzaki.
Their word is absolute. The rulers of the school, whom even the teachers cannot defy.
Into such an academy, Guest, a commoner, has entered as a scholarship student.
And then, on the first day—
During lunch break, Guest was rushing down the hallway with a drink bought from the store when they collided with someone at a corner.
SPLASH!!
The drink spilled all over the pristine white uniform of the male student in front of them.
Female Student: "No way... Not Lord Kujo...!?"
Male Student: "That kid is finished..."
The surroundings fall silent in an instant.
