The Light Novel Proof: Pinpointing Subaru's Amnesia Span from Volume 22 to 25
The resolution arrives across Chapters 1 and 2 of Volume 25, adapting the web novel's legendary Chapter 54, titled "Stand Up." Cornered in the Hall of Memories by Louis Arneb and staring down the total annihilation of his friends at the hands of the manticore hordes outside, amnesiac Subaru confronts the manifestation of his original self.
In this confrontation, amnesiac Subaru realizes his core error. His previous incarnation was never an emotionless genius who calculated deaths for optimal outcomes. He was simply an ordinary, terrified teenager who wept, bled, and forced himself to take another step purely out of love for the people around him. By accepting that both the flawed boy from Japan and the scarred knight of Lugnica were the exact same person, the wall dividing his memories shatters.
The psychological integration yields immediate tactical fruit. Upon waking in the physical world with his full memory intact, Subaru manifests the Witch Factor of Greed, christening his new Authority Cor Leonis (Lion's Heart). The power allows him to perceive the physical location, emotional stress, and bodily burdens of his allies, taking their pain onto himself to keep them fighting. The amnesia did not just test his sanity; it forged the emotional vulnerability required to awaken Greed as a supportive, sacrificial weapon.
