Studio WHITE FOX has officially confirmed that Re:ZERO -Starting Life in Another World- Season 4 will begin airing in Japan on April 8, 2026, bringing Subaru Natsuki back to the screen in the next major chapter of his grueling isekai journey.
The fourth season will cover 19 episodes split across two consecutive cours. The opening half, titled The Loss Arc, comprises 11 episodes and launches weekly starting April 8. After a short hiatus, The Recapture Arc will resume with the remaining 8 episodes from August 12, 2026. This split-cour format continues the series’ tradition of adapting substantial arcs from Tappei Nagatsuki’s light novels while allowing breathing room between major story beats.
The ending theme, Ender Ember, marks the return of MYTH & ROID, who previously delivered the Season 3 ending. This time they collaborate with TK from Ling tosite sigure as a featured artist, infusing the track with fresh vocal intensity. You can MYTH & ROID's comments here:
Following our work on Season 3, we are honored to once again perform the ending theme for Re:ZERO -Starting Life in Another World- Season 4 as MYTH & ROID feat. TK (Ling tosite sigure). Our new song, Ender Ember , was created around the theme of the lingering heat that remains after an ending. While carrying forward the time we have walked alongside Re:ZERO , we sought to capture and give shape to the emotions that resonate beyond the story itself. With TK joining us as a featured artist, his unique expression has brought a new intensity to the track. As our voices intertwine, the song carries a depth and energy unlike anything we have created before. We hope you will look forward to both Re:ZERO -Starting Life in Another World- Season 4, airing this April, and to “Ender Ember.”
Masahiro Shinohara returns to direct at WHITE FOX, with the majority of the key staff from prior seasons reprising their roles to maintain the series’ signature blend of psychological tension, intricate world-building, and emotional stakes.
Re:ZERO -Starting Life in Another World- centers on Subaru Natsuki’s relentless struggle after an abrupt summoning to a fantasy realm.
Natsuki Subaru, an ordinary high school student, is on his way home from the convenience store when he finds himself transported to another world. As he's lost and confused in a new world where he doesn't even know left from right, the only person to reach out to him was a beautiful girl with silver hair. Determined to repay her somehow for saving him from his own despair, Subaru agrees to help the girl find something she's looking for...
With the April premiere now locked in, anticipation continues to mount for Subaru’s next cycle of despair and determination. Season 4 will be available to stream on Crunchyroll with simulcast episodes following their Japanese broadcast for viewers worldwide.
