Episode 0 | Re:zero Kara Hajimeru Isekai Seikatsu

The series premiered with a double-length, 52-minute episode. Some streaming platforms or fan databases split this into two parts: "Episode 0" (1A) and "Episode 1" (1B). This episode introduces Subaru Natsuki’s sudden transport to a fantasy world and the discovery of his "Return by Death" ability.

This OVA functions as a prequel to the main series, detailing the meeting between Emilia and Puck. Because it takes place chronologically before Subaru's arrival, some fans consider it an "Episode 0" in terms of timeline. Re:Zero kara Hajimeru Isekai Seikatsu Episode 0

Fans occasionally mislabel the iconic Episode 18 as "Episode 0" due to its title, which signifies a major emotional turning point for Subaru. Recommended Viewing Order The series premiered with a double-length, 52-minute episode
