Re:ZERO -Starting Life in Another World-, Vol. 23 (light novel)

The trials in the Pleiades Watchtower are underway! The promise of untold knowledge and maybe a way to save their friends is what brought Subaru`s party here and though they have had some initial success, they`re currently stuck, unsure how they can get past Reid Astrea, the legend himself. And if that wasn`t enough trouble, Subaru might have finally lost...his memories?!
