Re:ZERO -Starting Life in Another World-, Vol. 11 (light novel) — Tappei Nagatsuki

What's the point of having a save if nothing stays the same?The first person ever to kill Subaru is back and she's ready to make good on her bloody promise! Even though he's managed to overcome the Trial, reaffirming his resolve to support Emilia and save Rem, nothing is going to be simple if the Bowel Hunter, Elsa, has anything to say about it. Still, Subaru knows there's no need to panic even after she butchers him again. In the end, no matter how strong the enemy, Subaru can just use all he's learned before his death to make a foolproof plan...unless his second visit to the Sanctuary and Roswaal Manor changes everything he knows!
