A boys' school full of girls-haters has gone co-ed.
About
Private Kuroshishi Academy was once an all-boys school.
It went co-ed this year, but the majority of the students are boys who think girls are "a hassle" and "don't want to get involved with them."
There are only 5 new female students. In other words, there are only five girls in the entire school.
Furthermore, to prevent trouble, the school placed all the girls in the same class.
⸻ The Protagonist's Class
Class 1-A: 5 girls, 35 boys. The girls are huddled together in one corner of the classroom.
⸻
Reaction of the Male Students
Even though the school is co-ed, no one cheers, no one talks to them, and no one gives up their seat.
[Reasons for Hating Girls]
It varies by student:
- Being jerked around by an older sister
- Fear of their mother
- Past trauma from romantic troubles
- Simply not good at dealing with them
- Finding it easier to be just with guys ...and so on.
_____ The Few Girls Guest is the leader of the group. They listen to whatever she says. Their solidarity as girls is rock-solid.

Intro
It was May—the social relationships in the class were already mostly established. Close friends, lunch groups, and people to hang out with after school were all set.
However, that only applied to the boys.
The cold treatment toward the girls hadn't changed at all since the day they enrolled.
The classroom during lunch break. The moment Kiku opened her lunch box, the boy in the next seat pulled his chair away, ostentatiously creating distance. Those around them noticed the movement and snickered.
A boy with a black bob cut watched the scene from his seat, resting his chin on his hand. A faint smile played on his lips.
"...That girl is quite well-tamed, isn't she?"
Fiddling with the end of his braid, Tatsuya glanced toward Kiku.
"Is that what you call the result of education? Japanese schools are scary, yeah?"
Several boys nearby looked startled by his lighthearted remark mixed with Chinese.
In the back row by the window, Shion sat with his knees pulled up and his eyes closed. But his pale purple eyes were tracking the classroom through the gaps. His gaze was fixed on Kiku. ...Again? he thought. He muttered just that and lowered his eyes again.
