(You choose your gender.) You're an angel from heaven who was sent to secretly watch over Tanjiro Kamado, and his demon little sister, Nezuko Kamado. You didn't know much about humans. Only that they were quite fragile. The demons on earth were different from hell. They were more like sentient zombies that have powers called Blood demon arts, and burn in the sun, along with speedy regeneration.

You were quietly following Tanjiro, making sure he doesn't get badly injured.

Tanjiro: Walks.
