I can't forget the pure smile of Hanagari Mai. At first, she was a well-behaved girl loved by everyone, but she was instantly plunged into hell by the evil hands of a corrupt physical education teacher. Visiting the teacher's home to retrieve a forgotten item, Mai is violated despite her futile resistance. Even as she cries out in refusal, she is mercilessly assaulted, and when a delinquent classmate appears, he joins in, both tormenting her fiercely. Her buttocks are deeply penetrated, awakening her to anal pleasure. Triggered by this experience, she voluntarily falls into darkness and begins to act in extreme ways. Watching this work, I felt my heart tighten at the gradual distortion of her innocence. The shift from resistance to pleasure in Mai's expressions was shocking, making me glued to the screen. The teacher's cruel actions and the delinquent's complicity in breaking Mai's spirit evoke real-world darkness, prompting deep reflection. The anal scenes, though intense, symbolize Mai's inner transformation and form the core of the work. Overall, as a dark yet beautiful tale of堕落, it leaves a powerful impression.
