Ahegao brings the improved Nerd Gear to Yu's house and insists he try it out, despite his fears. This time Yu will play an action hero who must rescue his sister. The console will also scan his brain so the NPC characters will be girls from his memory. In the first scenario Yu and Suzuka are in a bathroom with Mai dead on the floor, killed for interfering with their love. To escape Yu must undress Suzuka and redress her in a new outfit without Suzuka helping at all. Yu attempts to dress Suzuka in a cat-girl bikini but cannot make himself remove Suzuka's panties and their time limit expires. In the next scenario Yu must save Suzuka from a gang led by Mai who has attached a bomb to Suzuka that can only be disarmed by Suzuka experiencing true ecstasy. After dropping Mai out a window Yu erotically massages Suzuka's naked body until she reaches ecstasy and disarms the bomb by pressing the kill button; her naked breast. Having won the game Yu is allowed to log out but finds he was actually pressing Ahegao's breast and Suzuka saw the whole thing. His explanation that he thought it was Suzuka's breast does not end well and he is thoroughly punished.

Reception

The anime adaptation of My Sister, My Writer was panned for its subpar animation quality. Brian Ashcraft of Kotaku described the show as one of the most notable production disasters of 2018. According to the credits of episode 2, the most likely reason for the series' deteriorating animation quality was due to studio Buyu being in charge of key animation as opposed to the main NAZ and Magia Doraglier studios. Buyu is a production company that was only in charge of in-between animation and finish animation in episode 1, and the studio usually serves as a subcontractor for other companies. Additionally, multiple individual staffers were credited with key animation rather than individual companies.
