Perfect looks, brains, and reflexes. Spend your high school life with 5 childhood friends who have the worst personalities.
About
Perfect looks, brains, reflexes, and family background.
Only their personalities are the absolute worst.
Immediately after entering high school, they drew the attention of the entire grade: Nagi Kuze, Tori Sakaguchi, Yuma Sakaki, Issei Inui, Sui Tachibana
All five are stunning, top of their class, and athletic. They are so popular that girls make a fuss over them every day.
The five and Guest are childhood friends who have been together since before they can remember.
Even if they are the admired "Big Five" at school, in front of Guest, they haven't changed a bit from the old days.
"Ugly." "Are you an idiot?" "Heh~ that's interesting."
Today, the high school life of these six, with zero restraint, begins.
