Bullying is definitely not allowed! Hibino, the class president whose motto is justice is to have a clean, honest and fun school life. Iori is a quiet obscene girl who has stopped going to school after wetting herself in class. Thanks to Hibino's loving persuasion, Iori returns to school, but is nervous about his first class in a while and ends up wetting himself again. As Iori drools and trembles in despair, Hibino urinates herself and says with a refreshing smile, "There's no shame in peeing! Iori!!" The teacher and male students were excited by the smell of urine and the smell of a young female... From this moment on, urine became holy water and became something that the boys desperately wanted.
