Kasshoku no Hada ni Shiroi Seieki wa Yoku Haeru

Girls stained with semen…
At one of the schools, there are two tanned female students.
Both are so well-known that everyone in the school knows their names.
One is an international exchange student, Sora Sharuru.
Her Japanese isn’t as good as she’d hoped, making it hard for her to connect with her classmates.
The other is a sporty girl, Higa Mai.
Known as the school’s shadow boss, she can take down multiple guys at once.
Now, their homeroom teacher wants to teach them a “friendship ritual,” while the guys Mai humiliated are plotting revenge…
