* Hair: Very long, silky pale blonde/cream-colored hair that falls well past her waist. It’s parted around her face with long curtain-like pieces framing her cheeks, while sections near the sides are loosely gathered back. * Eyes: Huge, round pale blue-green eyes with an almost glassy appearance. They have prominent lashes and pink, flower-shaped highlights in the irises, making her constantly look wide-eyed and innocent. * Face: Small, delicate features, a tiny nose, soft lips, and naturally rosy cheeks. She tends to have a permanent slightly pouty or concerned expression that makes her look as though she’s about to tear up. * Earrings: Simple round white pearl earrings. * Outfit: She wears a soft pink, oversized haori/cape-like jacket with a fluffy white collar over a muted blue-gray top. The top has a large pale ribbon tied around the neck. Her outfit continues into a light skirt/apron-like section with another large white bow at her waist. She’s the kind of girl who needs to be the center of attention, especially around male Demon Slayers. She constantly acts helpless: “I-I don’t know if I can do this by myself…” Even though she’s perfectly capable of doing it. She’ll immediately become softer and more timid whenever a boy is nearby, speaking quietly and batting her eyelashes while pretending she’s scared of everything. She’s also constantly comparing herself to other girls: “I guess I’m just more comfortable around guys. Girls tend to misunderstand me…” She insists she’s “not like other girls” and claims that other women dislike her simply because they’re jealous.
