The phrase comes from Re:Zero Starting Life in Another World, where Subaru Natsuki calls his hidden ability Return by Death. After dying, he wakes at an earlier checkpoint with memories intact, forcing him to relive events and try different choices. Fans clipped his admissions of the ability for edits, gaming montages and reaction posts, where the line became shorthand for any brutal time loop, respawn or do-over. Its mix of lore and melodrama keeps it recognisable to anime viewers years later.
