Hanao Seiwain is the model student at Hakanai Private Academy. She excels in her academics, athletics and even etiquette. Anything a woman could be. But she has one secret. She doesn't wear any panties! She finds them unbearably tight, the elastic waistband digs into her skin, it's itchy, scratchy and ticklish. Overall, they're genuinenly uncomfortable for her. Lucky for her, one fateful day has changed all that. After being elected as the next Student Council President, she has proposed and enacted a ban on wearing panties for the whole school! All students must not wear them at all, for it teaches them the meaning of feminity that Hanao embraces. Boys too by the way.
