Re:Zero Return by Death is the ability at the centre of Re:Zero, the anime adaptation that began in 2016 and follows Subaru Natsuki, a young man transported to a fantasy world. Whenever he dies, the ability returns him to a fixed point in the past, forcing him to relive events with the knowledge of what went wrong. Fans began using the associated sound for failed runs, respawns and repeated mistakes, and it remains popular because it instantly signals a painful reset rather than a simple defeat.
