異世界帰りの勘違い！？

After two years of painful living in a different world, I and three girls from my class have finally returned to Japan.

However, due to various misunderstandings, I am rumored to be a delinquent harem bastard who skipped school for two years to hang out with the three girls.

Having lost our place in school, the four of us start a group meeting to somehow regain our youth and spend our days having fun.

Futhermore, as I occasionally get picked for a fight, the misunderstanding accelerates, and I become the king of the delinquents, feared by the other students.
