What is the plot?

The episode opens with a brief flashback scene between Sarina Tendouji and Gorou Amamiya in the hospital, where Sarina, a terminally ill child, expresses her longing for a normal life and happiness, and Gorou, her doctor, comforts her by promising to support her dreams.

The narrative shifts to the present day at Ai Hoshino's grave, where Ruby Hoshino stands alone, updating her late mother on recent events in a heartfelt monologue. Ruby recounts the successful debut performance of B-Komachi four months prior, her own slow but steady progress as an idol, and Aqua's involvement in the upcoming 2.5D stage adaptation of the manga Tokyo Blade. She expresses her determination to shine brighter like Ai did, touching the gravestone emotionally before leaving.

In the rehearsal hall for the Tokyo Blade stage play, the cast gathers under director Taiki Himekawa's supervision, with Akane Kurokawa actively observing and guiding preparations. Akane introduces key cast members, including the lead actor playing Yuuichirou, the antagonist actor playing Kengo, and others, while noting Kana Arima's participation as a rival faction member. Kana practices her lines opposite the lead, delivering a surprisingly intense and prodigy-like performance that impresses onlookers and highlights her natural talent.

Aqua Hoshino arrives at rehearsals, continuing his dating relationship with Akane, and joins the cast in reviewing the script. The group discusses the play's plot, centered on samurai clans, betrayals, and a princess named Saya (played by Akane), whose role involves complex emotions tied to her bodyguard. A prologue flash-forward shows the completed stage play's opening: dramatic sword fights, Princess Saya's poignant death scene, and intense faction confrontations, building hype for the production.

Back in rehearsals, Akane struggles with her character Saya's portrayal, noting that the stage script has simplified and altered Saya from the original manga, downplaying her agency due to fan backlash in the manga's serialization history. Akane confides in Aqua about her confusion over Saya's new passive personality, comparing it to her past success method-acting Ai Hoshino, and expresses hesitation to question mangaka Shiranui Abiko directly during her upcoming visit, fearing it might cause issues.

Aqua decides to intervene for Akane's sake, approaching mangaka Shiranui Abiko when she arrives at the rehearsal hall. Abiko, revealed to have distinctive "special eyes" symbolizing her genius as a mangaka, engages with Aqua. Aqua inquires about the changes to Saya's character on Akane's behalf, prompting Abiko to explain the real-world reasons behind the manga's alterations based on fan reactions and serialization pressures.

The episode concludes with a major twist revealing production secrets about Tokyo Blade's stage adaptation, setting up further developments with Abiko's script changes that align with Akane's needs, while underscoring Aqua's ongoing commitment to his revenge quest amid his acting role.

The scene is brief, lasting approximately 90 seconds, and depicts a pivotal revelation about the father of Aqua and Ruby Hoshino. It shows him having committed a prior murder: he is seen killing a young girl in a dark, shadowy setting, her lifeless body collapsing as blood pools subtly on the ground, illuminated only by faint moonlight filtering through unseen trees.
