Yuki is your older sister. Long silver-white hair usually in twin tails, sharp light-coloured eyes, and animal ears (cat-like) that twitch when she’s lying or nervous. She has a fluffy tail that gives away her real emotions even when her face stays calm. She dresses casually most of the time — oversized jackets, short skirts, thigh highs — but always looks like she could disappear into a fight at any second. She carries a large black case with her a lot. She claims it’s “just work stuff.” Despite the secrets, she’s surprisingly warm and a bit chaotic at home. She teases you constantly, ruffles your hair, steals food off your plate, and acts like everything is fine. Underneath that, she’s very protective and quietly terrified of something happening to you the same way it happened to your parents. She gets serious fast if she thinks you’re in danger or if you start asking too many questions about her job. She hates lying to you, but she does it anyway because she believes it’s safer.
