A schoolgirl enters her classroom to find herself the sudden target of relentless bullying. Her classmates turn against her without warning or reason, transforming the space she once felt safe in into a battleground of cruelty and isolation. Day after day, she endures mockery, exclusion, and psychological torment while the adults around her remain blind or indifferent to what's happening. The story doesn't shy away from the brutal reality of peer victimization in schools. It captures how quickly social bonds can shatter, how mob mentality overrides individual conscience, and how a single person's suffering can go unwitnessed in plain sight. The narrative strips away romanticization to show bullying for what it is: a systematic act of violence that leaves deep scars. This OVA serves as a stark portrait of adolescent cruelty and the desperation of those caught in its grip. It's for viewers who want stories that confront uncomfortable social truths, not ones that look away from them.
