The son of the school's principal is forced to join the student council.
He (protagonist) absolutely doesn't want this. The other students and teachers don't like him, but are intimidated by his father's power.
Only Yukari, the vice president, gives him grief ... and it's a bit too much.
When the principal's daughter can't take it any more, he snaps: Too much stress! These parasitic girls will feel his wrath.
