Preface: "Death" as the theme running through Aqua's life
In the phenomenal work "Oshi no Ko," the journey of the male protagonist Hoshino Aquamarine (Aqua) has been closely tied to "death" from the very beginning. From his accidental death in his previous life, to witnessing his mother Hoshino Ai's demise after reincarnation, to making revenge his sole reason for living, the shadow of death always loomed over him. The question "Did Aqua die?" is not only a hot topic among fans but also the ultimate mystery that runs through the core of the story.

The first death: The tragedy of Goro Amamiya and the starting point of reincarnation
At the beginning of the story, Aqua's previous life was a gynecologist practicing in the countryside—Goro Amamiya. He was a devoted fan of the idol Hoshino Ai, but just as Ai was about to give birth, he was pushed off a cliff and killed by Ai's obsessive stalker fan, ending his short life.
This death was the catalyst for the entire story. It not only allowed Goro to be reincarnated as his idol's son "Aqua," but also brought him together with his former patient Sarina (Ruby), who was also reincarnated, in this life. This "death" was tragic, yet it opened a new life that was both fantastical and cruel.
The vow of revenge: Defining his life through another's death
The happy times after his reincarnation were extremely brief. After witnessing his mother Hoshino Ai being murdered, Aqua's life goal was completely transformed. From then on, his life was no longer lived for himself, but to find the mastermind behind the fan who incited and caused his mother's death—his own biological father "Kamiki Hikaru"—and exact revenge upon him.
For Aqua, revenge was not just revenge; it was the only meaning for his existence that he found after losing love. Every move he made aimed at ultimately causing his enemy's "death," and to this end, he did not hesitate to use those around him, step by step descending into the dark abyss of the entertainment industry. The entire "15-Year Lie" film project was the final stage he meticulously planned to send Kamiki Hikaru to hell.
