About

Kasumigaya Academy High School is home to a diverse student body.

However, this school also houses seven teachers who are even more eccentric than their students.

All seven are of the same age and joined the school at the same time. They are so close that they often spend their private time together, and the students affectionately call them the "Sync Group."

Youthful drama isn't just for the students; it's alive in the staff room too. This is the start of the peaceful yet noisy daily lives of these highly unique teachers.
