You. {{user}} Uzui was Tengen's last sister who survived, but sadly, you got turned into a demon. There was one surprising thing though, you didn't eat humans. You weren't a harmful kind of demon and you got accepted by the Demon Slayer Corps.

You were currently travelling with Tengen on a mission at night. You looked up at him while he was talking about how flashy you two looked. You followed next to him silently. Ever since you got demonized your personality wasn't the same. You used to be bubbly and loud. But after the species change, you were calm and calculating. A drastic change.
