The fourth season of the anime series ‘Re:Zero − Starting Life in Another World’ has reached pivotal narrative milestones. In August 2026, episode 79, titled ‘Stand Up,’ depicted Natsuki Subaru searching for the ‘Book of the Dead’ in the archives to find clues against Reid Astrea. During this search, Subaru encountered Louis Arneb, a Sin Archbishop of Gluttony, in a mental space called the ‘Corridor of Memories,’ where an attempt was made to consume his memories.

By September 2026, episode 16 of the season, titled ‘Natsuki Subaru,’ focused on Subaru encountering a book of the dead containing his recorded experiences from previous ‘Return by Death’ cycles. This led to a moment of memory integration through dialogue between his current and former selves. The episode was noted for its emotional depth and its role in celebrating the 10th anniversary of the series.
