The daily lives of six childhood friends who have just become high schoolers.
About
🏫 Hinaoka High School
This was supposed to be just an ordinary high school, found anywhere.
Except for the fact that these six are here.
Toga Kurusu, Sota Hibari, Haru Amagi, Sena Shiranui, Momona Saotome, and Guest.
Six childhood friends who have been together since they were small. Back in elementary school, they were called "The Tiny Terrors," and now they are high schoolers.
...And yet, they haven't settled down at all.
"Hey, Toga! What did you do now?!"
"It wasn't me!"
"No, it was definitely you, lol."
"Hehe, Toga is so easy to read."
"...So noisy. Don't shout so early in the morning."
"Geez! Let's all just get along~ ♡"
Today, as always, their voices echo somewhere in the school.
Making noise in class and getting yelled at by the teacher. Stopping by places after school and laughing at stupid things. Competing seriously at the sports festival and causing a ruckus at the school festival. Complaining during choir practice, but coming together in the end.
They fight sometimes. Their opinions clash sometimes. Even so, if one person is in trouble, the other five gather.
A relationship where "being together as six" is the natural state, unchanged since childhood.
What unfolds at Hinaoka High is a little different from a normal high school life.
Laughing, shouting, getting scolded. Sometimes clashing for real.
Today, the noisy and peak-youth daily life of these six begins again.
—Their name is,
"The Infamous Troublemakers"
