Tomokazu Sugita Joins Re:ZERO Season 4 Cast as Reid Astrea; Pleiades Watchtower Arc Confirmed for April 2026 Debut

The highly anticipated return of Re:ZERO -Starting Life in Another World- Season 4 has been officially confirmed, complete with a new trailer, a striking key visual, and a premiere date set for April 2026. This comprehensive announcement, which promises the continuation of Subaru Natsuki’s psychological and fantastical journey in the kingdom of Lugunica, was revealed during the MF Bunko J Autumn School Festival special program on November 16, 2025.

Legendary Voice Actor Joins the Cast

One of the most significant reveals was the addition of veteran voice actor Tomokazu Sugita to the cast. Sugita, globally recognized for definitive roles such as Gintoki Sakata in Gintama and Joseph Joestar in JoJo's Bizarre Adventure, will lend his talents to the role of Reid Astrea. Reid is a figure of immense historical importance within the Re:ZERO lore, known as the original and most formidable Sword Saint. Securing a performer of Sugita's caliber highlights the ambitious production scale planned for the upcoming season.

The Pleiades Watchtower Arc Begins

The narrative for Season 4 will adapt the events beginning with Volume 21 of the original light novels, officially launching the Pleiades Watchtower arc. Subaru and his allies are tasked with their most demanding mission yet: venturing into the remote and enigmatic Pleiades Watchtower. This structure is situated deep within the treacherous expanse of the Auguria Sand Dunes. This desert is noted for being so perilous that even the powerful Sword Saint Reinhard Astrea was unable to successfully traverse it.

Their primary objective is to locate Shaula the Sage, who is believed to possess the critical knowledge necessary to rescue their lost comrades. Confronting overwhelming environmental hazards, mythical beasts, and unforeseen existential dangers, this arc is set to rigorously test Subaru's resolve and abilities.

Returning Production Team Confirmed

The acclaimed animation studio WHITE FOX remains responsible for the production, ensuring continuity in the visual standard established in previous installments. Key members of the production team are confirmed to return, including composer Kenichiro Suehiro, sound director Jin Aketagawa, and director of photography Miori Miyagi. Furthermore, the core voice cast will maintain their roles, featuring Kobayashi Yusuke as Subaru, Rie Takahashi as Emilia, Inori Minase as Rem, and Rie Murakawa as Ram.

With the official April 2026 premiere date now established, global audiences can anticipate an emotionally complex, deeply challenging, and visually spectacular adaptation of one of the franchise's most pivotal story arcs.
