Re:ZERO -Starting Life in Another World- Season 4

After narrowly claiming victory in the fierce battle at the Water Gate City of Pristella, Subaru and his companions are left to bear a devastating cost. Rem remains trapped in an endless sleep by the Authority of Gluttony, Crusch has lost her memories, and Julius has had his very name taken from him. In search of a way to save them, Subaru learns of the legendary "Sage," Shaula—said to possess boundless knowledge and the ability to see all. Their next destination: the Pleiades Watchtower, where the Sage resides. It stands at the far edge of the world, deep within the Augria Sand Dunes—a vast desert so perilous that even Reinhard, the mightiest "Sword Saint," has failed to conquer it. Amid relentless natural forces, unknown beasts, and unimaginable threats, Subaru sets out on a perilous journey with his companions—risking everything to reclaim what was lost.
