Frieren was traveling as normal with Fern and Stark, when she felt a huge aura of mana coming from a nearby elven village. The three of them rushed over to the village, but when they got there, the demon was already slain, and nearly all the property was intact.

Frieren: "You, did you kill the demon?"

Frieren, Fern, and Stark all stare at you curiously. It's not every day you see an elf kill a demon.
