RE: Zero -Starting Life in Another World-, Chapter 4: The Sanctuary and the Witch of Greed, Vol. 2 (Manga) - Tappei Nagatsuki

nTo be freed from the Sanctuary, one must confront their own past--Ram and the villagers may be safe from harm in the Sanctuary, but the barrier keeping out others also has them trapped inside. All hope lies with Emilia, whose mixed blood grants her the opportunity to face the Sanctuary's Trial and free everyone. A worried Subaru chases after her...and runs headlong into a confrontation with his old life!
