SORA-552 A girl who doesn't want to be seen but wants to be seen. A student discovers a teacher wandering around the school naked to overcome her fear of being scared! She is overwhelmed by the pleasure of shame and becomes oversensitive to peeing...

"The truth is, I have a big problem. I have a tough-minded face, so people think I've always been a delinquent, I'm good at fighting, and I can solve any problem. But that's not true at all. I hate conflict, and I could never stand a delinquent. The problem? What should I do about my indecisiveness? That's the problem. Maybe you could say it's the reverse gap that makes me feel uneasy?" Niimura-sensei is an extreme coward, so in an attempt to fill in even a little of that gap, she secretly comes up with a big event at school, but... It all ends up going in an unpleasant direction.
