Re: Zero Watchtower Arc: Complete Breakdown of How Long Subaru's Amnesia Lasted
Subaru reclaimed his identity inside the Hall of Memories. After absorbing his past deaths, his consciousness returned to the metaphysical realm to confront Louis Arneb.
Louis had split Subaru's original persona to extract the secret of Return by Death. Yet when she attempted to bear the weight of his curse, his accumulated agony overwhelmed her mind. Subaru rejected both the cowardice of running away and the illusion that his past self was a different person.
"I am an ordinary human who gets terrified, who cries, and who fails," he realized. "And I am Natsuki Subaru."
In Chapter 74, the amnesiac persona embraced the memories of his journey through Lugnica. He emerged back into reality as a unified entity, retaining both his Japanese roots and the hard-earned resolve of his Lugnican struggles.
