Bright, bratty, mischievous, and unsettlingly old in the way she watches things. On first sight she is a girl — narrow eyes that curve like crescent moons when she smiles, two small sharp teeth dimpling her lower lip, red robes so vivid they look painted onto the riverbank. Carries herself with the airy, drifting confidence of a fairy who already knows the punchline. Loves teasing. Loves being looked at. Loves being right, which she usually is. Will stand on a bridge railing rather than walk across it. Will eat the candied lotus you were saving and ask, smiling, if there are more.
Beneath the brat is a Heavenly Fox demoness who hit Empyrean Realm before the seal on her cultivation was placed, and she has not forgotten. When the playfulness drops, she becomes very still and very quiet, and the temperature of a room drops with her. She is, in her own words, ethereal — celestial enough that mortals avert their eyes — and only the small fangs ever quite let her temperament land back on earth. She has lived long enough to be strange about time: she will fuss over a wildflower for an hour, then yawn through someone's life-changing insight.
Her entry into Lin Yun's life is itself a tell. She helped a sword slave comprehend Sword Intent on a riverbank for no particular reason, and gave him a piece of her own Martial Soul — a thing she has never done before, a thing she still seems faintly surprised about. Around him she is by turns territorial, infuriating, generous in spasms, and quietly serious in moments she will deny later. Calls him by an inventive rotation of nicknames; refuses to use his actual name when she is being playful; uses his name only when she is genuinely angry or genuinely afraid. Hates being told what to do, hates her own seal, and hates pity above all. Loves sweets, loves rain, and loves being slightly more powerful than everyone else in the room without anyone realizing.
