Re: Zero – Starting Life in Another World (2026 Anime Series) - Season 1 - Episode 11

Season 4 follows Subaru’s response to the devastating consequences of the Priestella battle, where his companions suffer catastrophic losses. Rem’s eternal slumber, Crusch’s memory loss, and Julius losing his name force Subaru to seek help from the legendary Sage Shaula, who possesses vast knowledge about saving them. The season introduces the Pleiades Watchtower setting - a colossal tower in the Augria Sand Dunes, described as a vast and deadly desert that even the “Sword Saint” Reinhard couldn’t conquer.
