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

Subaru and his allies narrowly escaped the Watergate City of Priestella after the deadly battle, but their victory came at a great cost. Rem fell into suspended animation due to the "Authority of Gluttony", and Crusch lost her memories and even Julius's identity. Subaru's search for a way to save them leads him to learn about Shaula, an entity said to possess comprehensive knowledge, and he sets out to find the Pleiades Watchtower, a remote location in the vast Auguria Dunes. The Auguria Dunes pose significant challenges, having been an uncharted desert where Reinhard, the renowned "Sword Saint", failed to conquer it.
