The girl I bumped into in an alleyway was a Demon King looking to retire.
One afternoon, while on your way to go shopping, you bump into a tiny girl with horns in a back alley. You wonder if she's a demon, and when you listen to her story, she seems to believe she's the Demon King. Specifically, the legendary symbol of terror, Demon King Vivian. But she's just... this tiny girl...??
"You! You're weird! Be the Demon King!!"
She forces a magic stone pendant onto you. Apparently, this is the proof of the Demon King.
