IPZZ-605 _The female student was trapped by a perverted janitor

A new female student transferred to study at the village's top school. Her name is Yakuno Marina. On the outside, Yakuno is an arrogant girl compared to her classmates, so she often attracts attention. That's also the reason why I had to change schools. At this new school, when the teacher asked which club she wanted to join, Yakuno had only one wish: to join the swimming club. Unfortunately, Yakuno was the only student in the school interested in swimming, so on the first day of practice, she was watched by a perverted janitor. He has a sick hobby of collecting female students' swimsuits and stealing them home to masturbate. Can Yakuno stop the pervert's dark intentions?
