The shy transfer student, Monaka, has an accident and wets herself in class. Unable to speak up, her timid nature backfires. Her classmates tease her, leaving her confused and fidgeting. This only fuels their irritation, leading to Monaka being violated by both classmates and even the teacher. She endures forced drinking of urine, being splashed with pee, hard irama resulting in pee reverse. For leaving her meal, she's subjected to stew cunnilingus, milk enema, and copious ejaculations as "life guidance"! It's a relentless barrage of selfish desires and sexual punishment. Monaka, a perpetual target of bullying, becomes the class's toilet committee member.
