Re:Zero kara Hajimeru Isekai Seikatsu 4th Season

Subaru and his allies leave the battle for Priestella with an incomplete victory. Gluttony's Authority has devoured Julius's name and Crusch's memories, while Rem remains trapped in a sleep no one knows how to break. Searching for a way to recover what was lost, Subaru finds one remaining lead: the Sage Shaula, said to possess knowledge found nowhere else.

Shaula waits at the Pleiades Watchtower beyond the Augria Dunes, a desert so dangerous that even the world's greatest warriors cannot cross it casually. Subaru, Emilia, Beatrice, and their companions venture into a land of storms, unknown beasts, and lethal obstacles where reaching the tower is itself a trial. Before they can ask for answers, they must survive a place that seems determined to keep everyone away from the truths hidden at its center.
