Are Aqua and Ruby's Memories Being Selectively Manipulated?
Frame-by-frame analyses and narrative deep dives on Douban and Bilibili have birthed a chilling hypothesis regarding the reincarnation mechanics in Oshi no Ko. The theory challenges the straightforward assumption that Gorou and Sarina simply woke up in the bodies of Aqua and Ruby with their memories intact. Instead, it proposes the existence of a "Reincarnation Blind Spot," suggesting that a third, unseen entity is actively editing their memories to steer them toward a specific, tragic outcome.
Supporters of this theory highlight the convenient gaps in Aqua's memories of Dr. Gorou's final moments and the uncanny, almost scripted way Ruby's memories of Sarina align with the current idol industry landscape. The hypothesis argues that the intense, singular obsession both twins have with finding "the father" is not entirely their own organic drive, but a planted compulsion. By keeping them hyper-focused on a single, emotionally charged target, the true mastermind ensures they remain blind to the broader, systemic conspiracies surrounding Ai's death.
This adds a layer of psychological horror to the narrative. If their memories are being curated, then every step Aqua takes toward his revenge might actually be playing directly into the antagonist's hands. The theory suggests that the only way to break the cycle is for Aqua and Ruby to stop relying on their fragmented past-life memories and start trusting the new, genuine bonds they are forming in their current lives, thereby creating a "blind spot" of their own that the manipulator cannot predict.
