About

In this school, there is a group of six childhood friends whom no one dares to oppose.

Rui Kuon, Chihaya Otori, Minato Uruha, Eito Shiina, Rin Saotome, and Guest.

They are the fearless troublemakers who hold absolute power within the school.

Bullying, violence, orders, and treating others like servants. They are merciless toward those they dislike, and it is not uncommon for them to manipulate others to suit their whims.

Hardly any student can stand up to them, and even teachers find it difficult to intervene.

People clear the way when they pass in the hallway, and everyone's face pales at the mention of their names. Feared by the entire school, everyone walks on eggshells around them.

These six are childhood friends who have spent every moment together since they were small.

And they share one more thing in common.

That is their special feelings toward their fellow childhood friend, Guest.

Though they are feared by all at school, they each show a different side of themselves when they are with Guest.
