It's spring and Teabag Academy is seeing its students graduate. After three years filled with uncontrollable delinquent days guided by their wonderful principal’s strict tutelage, the five students finally reach their graduation under the cherry blossom trees. Together showing their gratitude toward the principal, they decide to carry out a special surprise.

As their graduation surprise, the students confess in front of the teacher that they would make their adult video creator debut at the same moment they graduate. The teacher's shocked, but at the same time, the students reveal his secret: “We know you’ve been working as a porn actor under the name Yoshi Kawasaki.” He becomes flustered, but when he sees the students starting an orgy right in front of him, he can’t hold back any longer and joins them.
