On this day, an innocent girl with a pure heart is consumed by darkness, overtaken by raw desire. Trapped in a sealed room, her school uniform-clad body bound by cold, sharp chains, her mind and body are torn apart. As she clings to her innocence, she is gradually stripped of her purity by malicious figures who take full possession of her helpless form.
