CAWD-960 | Four girls from a co-ed metropolitan high school's after-school club break school rules by letting loose. Karin, Meisa, Yuna, and Itsuki.

Four childhood friends who have been together forever and attend the same school
They go to school together, spend recess together, eat lunch together, and go home together
They've spent so much time together...and they thought they'd always be best friends.

One day, Meisa, the cheerful and mood-maker, kisses a teacher...
Itsuki and Karin witness this and are shocked.
When they questioned her about it later...
"Actually, Itsuki mutters, "I like him too..."
"Me too," "Huh? Me too," all four of them surprisingly like the same teacher.

A middle-aged teacher...that doesn't matter
It's against school rules, or rather, against the law...that doesn't matter
What people think is out of the question.
The feelings of love in your teens are devoid of any sense of composure
and are simply overflowing with passion

When a panicked Yuna tries to have him all to herself
Itsuki and Karin decide they can't let this slide this time
and the three of them fight over the teacher, creating a harem
Meisa watches from afar...

Later, they gather the teacher for their first fight.
They decide who is the best
and a ruthless battle for him begins.

Who will be chosen...?
