Having actually watched this work, the content was truly shocking. The despair of the fragile heroine Aoi, suddenly attacked on her way to school, was vividly conveyed through the screen, with a tense atmosphere portrayed realistically. Particularly impressive were the relentless attacks on the buttocks and the bathroom scene, both of which had high visual quality and paired excellently with bondage. The fragile beauty of Nakajo was enhanced by the bondage, especially the gag scene, which was highly erotic and breathtakingly intense. I felt that this series should include a gag every time, as its impact is so profound. Starting from the confinement scene in the warehouse, the process of physical and mental transformation through daily sexual training was depicted meticulously, adding depth that draws viewers in. The despair of crying and screaming with no one to help, combined with the heroine's inner changes, lends a rich dramatic quality to the work. Overall, the skillful combination of bondage and masochistic elements makes it a masterpiece that balances entertainment and artistry.
