: Aqua has grown into a cold, calculating teenager. He is focused on finding his and Ruby’s father, whom he believes orchestrated Ai’s death. He assists Director Taishi Gotanda to learn the ropes of the industry from the inside.
The paper proposes that Ruby’s function is to haunt Aqua. She reminds him of what he has lost: the ability to want something purely. When Ruby declares her dream, Aqua’s silent, calculating stare is the look of a man who has already sacrificed his own dreams for revenge. Episode 2 thus establishes a tragic dyad: the brother who performs everything but feels nothing, and the sister who feels everything but cannot perform to industry standards. Oshi No Ko Ep 2
A central conflict in this episode is the divergence in the twins' paths.

ends on a melancholic note. The Sweet Today production finishes, averting disaster. Kana thanks Aqua, believing he saved her. Ruby is thrilled. But Aqua walks away, adding Kana to his "toolbox."

provides the answer. Titled “Third Option,” this episode serves as the true beginning of the series’ identity—a dark, psychological exploration of the Japanese entertainment industry, viewed through the eyes of revenge and ambition. It is a masterclass in tonal shifting, moving away from the spectacle of Ai’s death and into the slow-burn mechanics of showbiz politics.
Aqua (the reincarnated doctor, Gorou) has also grown. On the surface, he is a handsome, stoic high school student. But internally, he is a shell of his former self. Driven purely by the desire for revenge, he has dedicated his new life to one goal: finding the man who murdered Ai—the same man who orchestrated Gorou’s own death prior to the series’ start.
In contrast to Aqua and Kana’s calculated sorrow, Ruby (the reincarnated Sarina) represents uncut, raw ambition. Her desire to become an idol is not mediated by trauma—it is a joyful, almost manic reclamation of the childhood cancer that stole her first life. The episode cleverly positions Ruby as the narrative’s moral blind spot. While Aqua deconstructs performance, Ruby embodies it without irony. Her dancing and singing in the episode’s closing montage are technically imperfect but emotionally overwhelming.
