Re:ZERO -Starting Life in Another World-, Chapter 2: A Week at the Mansion, Vol. 1 (manga) — Tappei Nagatsuki

What you forget, I'll always remember.
Using his ability to repeat past events, a power named "Return by Death," Subaru has saved the half-elf girl Emilia from a grim fate. However, his celebration is violently cut short. Subaru now wakes up in a large mansion, unsure of whether time has moved forward. Greeting him are the maid sisters Ram and Rem, whose verbal jabs sting with every word. It's a chance for a new life, but is Subaru in more danger than he realizes?
