Chikan Kenkyuushitsu

Sinopse

It's the summer of 1999, Tokyo.

Due to his awful academic performance, Okita Takashi, a student in his fourth year at Tounan University has to undertake further special lessons during summer break given by Sagara Yuuko, the teacher responsible for the seminars he attends.

The topic of these lessons is on the "Psychology of Molestation".

His task is to hand in a research paper on this topic which is due by the beginning of the new semester. Furthermore, he is instructed that his research method will be to collect data from real-life experiences.

Not long after, Okita is readily investigating commuter trains or the internet to collect data samples.

The victims he chooses are six girls, each of different archetypes and ages. All of them are virgins suffering under trauma.

- housewives whose marriage had turned cold - high schoolers who give sex the cold shoulder - female office employees with desires for getting raped

All of them have overlaps: They dwell in the big city, suffer under emotional and sexual dissatisfaction and their mental health took a deep dive.

While earning money from his part-time job Okita continues to molest for his report, but soon finds himself becoming more and more addicted to it.

And while he ventures into a abyrinth of disturbed desires, he might step over a line of which he won't be able to return anymore.
