Mahiru faces a significant decision: Yukine offers her a project that could advance her career. Kiui advises her to decide for herself but points out that Kano might also be affected. To learn more about Yukine, Mahiru turns to Mei, who provides her with a detailed background story and ultimately reveals that Yukine might be behind the scandalous "LookIdiot" account.

Kano unexpectedly calls Mahiru and praises her art despite minor flaws. Mahiru seizes the opportunity to tell Kano about Yukine's offer. Kano, visibly concerned, warns Mahiru to be cautious. Mahiru avoids bringing up Kano's issues with her mother and focuses on informing Kano about the possibility first.

During the project presentation, Mahiru is showered with praise. The project proposes that Mahiru's art be projected in a public park while the SunDolls perform with 3D avatars designed by Mahiru. Yukine, impressed by Mahiru's talent, emphasizes that the project has nothing to do with Kano and that she was solely inspired by Mahiru's work.

A flashback reveals Kano's strained past with the SunDolls. Yukine had introduced Kano as the new central figure, believing she was doing her a favor. However, the other members saw this as nepotism and rejected her. Yukine advised Kano to silence her critics with her talent. Influenced by Yoru's mural, Kano wrote her own lyrics and experienced a profound artistic moment.

Kano discovered that Mero was behind the "LookIdiot" account, which exposed scandals of rival idols. Outraged by these unfair tactics, she confronted Mero and physically attacked him. Yukine saw this as betrayal and an obstacle to her dream, leading to Kano's expulsion from the group.

Kano struggles to accept Mahiru's decision to join Yukine's project. She feels abandoned and betrayed. Despite understanding from Kiui and Mei, Kano lashes out at Mahiru, calling her selfish and a "jellyfish that can't swim at night," which deeply hurts Mahiru.
