The story follows undercover investigator Ai, who pursues a man from her past with a humiliating experience, targeting the leader of an international fraud group, Ōki, using her honed skills for infiltration, but her M-cup bust is too conspicuous, leading to repeated discovery and continuous violation. I watched this work and felt that Ai's body, especially the depiction of her super-large bust, was overwhelming, with high destructive power in clothing scenes, hitting my preferences. However, as an investigator-themed piece, a simpler plot could have better utilized Ai's physical assets; the excessive inclusion of bizarre settings made the descent feel awkward, lacking freshness and seeming to just push the M-cup aspect. I love scenarios where a righteous investigator falls, but I rarely recall seeing it done with proper drama; if well-made, it could be an interesting work, and I hope a director capable of this emerges. Some comments mention purchasing at Daikokuya, but criticize the poor acting and disappointing lead-up to sex scenes, leaving an overall regrettable impression.
