Everything about the secret, closed-door new employee training held in utmost secrecy by a notorious publishing company is revealed here! This training program, irregularly conducted by Digista Inc. for its editorial staff, invites AV actors with over five years of professional experience as instructors to teach the highest-level practical techniques in the adult industry. The implementation of this training and the selection of participants are entirely at the discretion of the training supervisor, and its contents are strictly prohibited from being disclosed externally unless specifically requested by the chief editor. Furthermore, even the participants themselves are kept completely in the dark about the details until the day of the training. Only female staff members who have been employed for less than three months are eligible to attend, making the criteria extremely strict. The training supervisor is obligated to record the entire training process on video. Chiba, who transferred mid-career to pursue her long-time high school dream of becoming an editor, works harder than anyone else. However, she struggles to grasp tasks quickly and lacks efficiency, raising doubts about her suitability as an editor. The supervisor had been considering termination if no improvement was seen by the end of her probation period, but decided to accelerate the evaluation by enrolling her in this training.
