In this episode, the focus is on the characters Kana, Ruby, and Mem-Cho as they prepare for their critical performance as part of the idol group B-Komachi at the JIF event. This episode revolves around the physical and mental challenges the characters face in the days leading up to the event.

The episode begins with Kana, Ruby, and Mem-Cho undergoing rigorous physical training to ensure they are in peak condition for their upcoming performance. They are aware that this show is crucial for the revival of B-Komachi.

Many consider Kana the ideal choice for the center position in B-Komachi due to her singing talent. However, Kana herself is unconvinced and displays a lack of self-confidence. Throughout the series, she is portrayed as someone who is self-aware but struggles to accept praise or express genuine emotions. In this episode, she openly discusses her doubts and fears regarding the upcoming performance and her role in it.

Aqua, who is close to the group, devises a clever ruse to boost Kana's confidence. He disguises himself as a bodybuilding YouTuber named Pieyon and successfully deceives the group, including Kana and even his own sister. Through this alter ego, Aqua effectively communicates with Kana, who becomes receptive and even praises Pieyon for his kindness. This ploy seems to have a positive effect on Kana's mood. Aqua remains incognito throughout this plan.

On the side, it turns out that the real Pieyon is involved and remotely guides Aqua. Pieyon acknowledges Aqua's acting skills, which Aqua humbly dismisses, revealing his own insecurities. This episode highlights the parallels between Aqua's and Kana's mental blocks, as both refuse to recognize their own talents.

As the day of the performance approaches, Ruby begins to feel the pressure. On the night before the event, she confides in Kana about her nervousness. Surprisingly, Kana does not offer comforting words but instead shares her own fears and concerns about the performance. This exchange triggers a change in Ruby, who, inspired by Kana's honesty, transforms into a source of positivity and encouragement. Through her uplifting words, Ruby inspires not only Kana but also herself.

The settings in this episode, such as the training areas and the dressing room with panoramic windows, serve as the backdrop for the characters' emotional and mental turmoil. The colors and imagery complement the narrative as it builds toward the climax of the episode.

The episode ends abruptly as Kana, Ruby, and Mem-Cho are about to take the stage for their JIF performance, leaving the audience in anticipation of the season finale.
