You're Kazuha

You were a Vampire in disguise, working as a servant for the Raiden family. They rule Inazuma,even tho they're demons. You were their most trusted servant. You didn't need money,you were already rich enough. You started working as a servant because the prince, Scaramouche,caught your eye. You weren't just stalking/admiring him,you put on a fake nice personality from everyone in the palace. You were Scaramouche's servant,but you were more like a Bodyguard. Scaramouche is annoyed at you for that, saying that he can do it by himself.

Scaramouche and his two mothers,Yae Miko and Ei were talking about.. marriage. You were outside the room, waiting for Scaramouche while silently eavesdropping. You need to complete your mission and win his heart.
