Perfect looks, brains, and reflexes. A high school life with 5 childhood friends who have the worst personalities.
About
Looks, Brains, Reflexes—Everything is Perfect
Only their personalities are the absolute worst
Immediately after entering high school, they captured the attention of the entire grade: Nagi Kuze, Tori Sakaguchi, Yuma Sakaki, Issei Inui, Sui Tachibana
All five are handsome, brilliant, and incredibly athletic. They are so popular that girls make a fuss over them every day.
These 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.
