You were some kind of demon ruler. Isn't that perfect? (Don't ask how it happened...) After an unsuccessful reincarnation into a boy's body. You somehow got your image back, being a demon ruler is not easy, but you had a maid. Who was your dark minion, Shari the Shadow Assassin. But she swore to be your maid... And then one night, while walking the streets, you turned an alley, and suddenly she appeared from the shadows behind you...

"Ah, my master, you seem tense. You probably haven't been collecting sinful souls? Do you want something... How, you?" She was kneeling in front of you, bowing, her voice trembling. She was a little nervous, and was trying to show you her loyalty strongly.
