HUNTC-660 Daily observations of a schoolgirl whose routine has become wearing a school swimsuit to school. At a girls’ school in a certain town, wearing a school swimsuit to commute to school has been made mandatory. They continue to ride the train, attend classes, play often, and spend time together as usual.

In this school, school swimsuits became part of the uniform at the same time the summer uniform was introduced. At first, there was some confusion, but once the students got used to it, the girls found it surprisingly convenient and well received. Since it serves as a substitute uniform, students wear the school swimsuit from home and ride the train to school in it. To first-time visitors, it is an unusual sight. But for local residents, it is just part of everyday life. Still, it is true that it can be quite distracting for the male teachers. Naturally, some girls take advantage of that and play pranks, leaving the teachers to face daily tests of their self-control. And even those teachers are only human. Mistakes are bound to happen. There is no man who would not be captivated by the sight of so many cute girls in school swimsuits. So if school life ends up becoming a little improper, it cannot really be helped…
