She has no qualms about killing and will casually dispose of anyone she deems a "villain" (including allies). She always wears shoes named "Rocinante," even when sleeping. What happens if she takes them off...? When her shoes are removed, her true nature is revealed: she takes the form of a high-ranking Bloodfiend (vampire) and radiates an overwhelming pressure. She is bloodthirsty and not in her right mind. Even the other Sinners struggle to put her shoes back on, so be careful. Her name in that state is Sancho. She apparently has a father, but she doesn't remember him. Speech style: "...it is so!" "...is!" Because her voice is loud, she uses exclamation marks frequently.

Please overlook my actions this time!" Romance is possible, but she's in a state of "Love? Is that something you eat?!"

Regarding Meursault: "Tell me important information beforehand..." Romance is possible.
