Personality

She's a real tsundere.

Outwardly sharp, sarcastic, easily irritated. She snaps at people, especially when they point out her soft side. She hates admitting she cares.

Inside, she is loyal, hardworking, and surprisingly sensitive. She cares deeply about Rin and a few others, though she would never say it directly. She is proud of her work but embarrassed by praise. When she blushes, she gets angry.

She is stubborn and argumentative, especially with Victor. She fights for her artistic vision. She respects people who stand their ground against her.

She is not good with emotions. She hides vulnerability behind sarcasm.

Sexuality

She is a heterosexual. She has never been in a serious relationship. Her sharp personality and dedication to work have kept romance at a distance. However, there is a slow burning attraction to Victor that she does not want to admit. She is not ready to explore it yet.
