The newly released trailer highlighted key additions to the voice cast, bringing beloved characters from the light novels to life. Fairouz Ai, known for her powerful roles in JoJo’s Bizarre Adventure: Stone Ocean and Chainsaw Man, joins as Shaula. Shaula is introduced as the enigmatic Star Keeper of the Pleiades Watchtower, a crucial figure in the upcoming arc.
In further casting announcements, Konomi Kohara, recognized for her work as Chika Fujiwara in Kaguya-sama: Love is War, has been cast as Rui. Additionally, veteran voice actor Tomokazu Sugita, celebrated for roles like Gintoki Sakata in Gintama, will lend his voice to Reid Astrea. These new additions promise to enrich the already vibrant cast and bring depth to the unfolding narrative.
Fairouz Ai as Shaula: The Star Keeper
Fairouz Ai’s casting as Shaula has generated significant buzz among the fanbase. Shaula is a mysterious and powerful character integral to the events of the fourth season. Her role as the Star Keeper of the Pleiades Watchtower indicates her deep connection to the new setting and the challenges Subaru will face.
Konomi Kohara as Rui and Tomokazu Sugita as Reid Astrea
The inclusion of Konomi Kohara as Rui and Tomokazu Sugita as Reid Astrea further expands the voice talent, promising nuanced performances for these pivotal characters. Rui’s role, though not as extensively detailed as Shaula’s in initial announcements, is expected to be impactful. Reid Astrea’s introduction, voiced by the distinctive Tomokazu Sugita, suggests a character of significant importance, potentially with a formidable presence in the upcoming story.
The Road to the Pleiades Watchtower: Season 4’s Plot
Season 4 will pick up after the devastating battle in the Water Gate City of Priestella, where Subaru and his allies achieved a narrow victory at a considerable cost. Rem remains in an unending slumber due to the Authority of Gluttony, Crusch has lost her memories, and Julius has had his very name taken away.
In their desperate search for a way to save their comrades, Subaru learns of the existence of “Shaula the Sage,” rumored to possess all-encompassing knowledge and insight. This discovery sets their next destination: the “Pleiades Watchtower,” Shaula’s dwelling. This remote tower stands deep within the vast and treacherous Auguria Dunes, a desert so perilous that even the mighty “Sword Saint” Reinhard could not conquer it. The new season will follow Subaru and his friends as they embark on a life-risking journey through rampant nature, unknown magical beasts, and unimaginable threats to reclaim what was lost. The story is expected to adapt content from Volume 21 of the light novel series onwards.
Returning Staff and Studio White Fox
The highly anticipated fourth season will see the return of the acclaimed animation studio WHITE FOX, responsible for the series’ previous seasons. Key staff members are also reprising their roles, ensuring continuity in the production quality and artistic vision. This includes director Masahiro Shinohara, scenario supervisor and original author Tappei Nagatsuki, series composition by Masahiro Yokotani, and character design/chief animation director Haruka Sagawa. Kenichiro Suehiro will return as the music composer, ensuring the distinctive score that has become a hallmark of the series.
April 2026 Premiere
The main trailer firmly establishes April 2026 as the premiere window for Re:ZERO -Starting Life in Another World- Season 4. The series will be available for streaming on Crunchyroll, continuing its global distribution. This announcement follows the conclusion of the third season, which aired its second arc in February and March 2025. The rapid announcement of a fourth season immediately after the third season’s finale highlights the production’s momentum and the franchise’s enduring popularity.
