I was drawn into this work by the shocking theme 'The Brainwashing Ring Really Existed.' SOD's user-first philosophy shines in this project, with a brilliant setup where four female employees are forced to pretend to be brainwashed due to a foreign director's interview request. However, as the commands escalate, the actresses' acting skills are fully displayed. Particularly impressive is Ms. Kametani's facial expressions, which transition from showing disgust at first to happily calling someone 'Master' and sucking the dick of a disliked person after putting on the brainwashing ring and heavy makeup—this scene is breathtaking. The acting and makeup are very meticulous, creating a sense of realism, but it's a pity that it's just 'pretend.' While the director's skill is commendable, if it were a real brainwashing scene, satisfaction would have been higher. Also, despite the foreign director setting, the lack of actual foreign male actors is disappointing, and I hope for an orgy scene with foreigners in the next installment. Overall, SOD's video production techniques are excellent, and all performers' passionate acting stands out, but I question whether the project's potential was fully utilized. Still, my attachment to this series is strong, and I greatly look forward to future developments. The immersive worldview makes you want the brainwashing ring, offering a work that can be enjoyed in the gap between fantasy and reality.
