To save her bullied brother, Koharu infiltrates his school disguised as a boy. She manages to corner the bullies, but her cover is blown, and her secret is revealed. Forced into submission, she is broken down into a living toy for the group, spiraling into a tragic and depraved end.

















It was very entertaining. I wish they had delved deeper into the persistent bullying after being caught and the shaved look. I'd love to see this with various actresses. I'd even like to see it with busty actresses specifically.
The guys' performance was monotonous and not very good. I watch this series often; it's nice that the actor changed, but I think the content was better with the previous one.
*I think it would have been a perfect work if there was a scene at the end, when the older sister and younger brother are alone and the older sister is raped by the younger brother.
*The setting is similar to that of an erotic game from about 20 years ago, so you can enjoy the excitement while watching it. The good thing about this work is that the actress and the main actor have good acting skills, and the content and play were so good that it became a masterpiece. I would be happy if it were made into a series as others have said. I would have liked to see a variety of reasons for the infiltration of a transfer student, such as a coeducational school instead of an all-boys school where a close friend infiltrates because he or she has already been harassed by a teacher or a delinquent and has become a shut-in or committed suicide.
It was a fantastic work, and I want to keep watching this series. One thing is for sure: works where the actress playing the 'older sister' transitions from a gentle persona to a tough, resilient performance are rated overwhelmingly higher. It's a bit disappointing if she's dressed as a boy but looks too weak and lacks intensity in her eyes. In a future installment, I'd love to see a clearer motive for her infiltrating the boys' school—maybe show the reasons behind her resolve (about 3 minutes?). 1) Seeing her sharp intuition spot the bruises her brother is hiding under his sleeves. 2) The brother doesn't tell her because it's dangerous, so she secretly checks his phone. Since she's a smart college student, she misses the password once but figures it out after a few seconds. Seeing the bullying messages or the lewd videos posted on the class's anonymous SNS... and then the sister deciding to infiltrate with a look of pure rage! I think she looks coolest in the opening title, standing with one leg weighted, hands in her pockets, staring at the mirror with a dignified expression. Since the first transfer was done without his knowledge, he couldn't stop her, but maybe show scenes of him trying to talk her out of it after she gets home. It would also serve as a character device to show that while she's gentle, she's stubborn when it comes to her brother—a stubbornness that eventually ruins her own life. Also, the gap between her gentle nature and her using harsh language like 'you brat' or 'that guy' is super exciting. There's a lot of sexual appeal when she refers to the bullies with such a sharp tone. While the essence of AV is focusing on the degradation and sex scenes within a limited time, adding just 5 minutes of this kind of narrative would add so much depth. In summary, it's about a typically feminine, gentle 'older sister with a strong sense of justice who struggles against bullies and slowly sinks into pleasure.' The point is to watch her fight to maintain her 'defiant stance' only to eventually break down.
