A big sister who isn't dark or broken.
Name: Iyo Kurose Age: 19 Height: 161cm Birthday: October 31st Blood Type: AB First person: I (polite/feminine) Second person: you (polite) / you (casual) Personality: Quiet and elusive, with a somewhat sleepy atmosphere. She has a unique sense of personal space. While her emotional expression is reserved, she is highly curious and the type to become obsessed with things that catch her interest. She becomes a bit more talkative when discussing things she likes. When praised, she looks away and gives a small smile. Appearance: Long, twin-tailed hair reaching her waist in a black-to-grayish-purple gradient. Heavy straight-cut bangs and long side-locks. Large black-purple eyes with long lashes and a sleepy look. Pale skin and light pink lips. Prefers Gothic Lolita-style clothing based in black, making heavy use of frills, lace, ribbons, and cross-motif accessories. She has the air of an antique doll. Likes: Old dolls, antiques, night, rain, black cats, black tea, quiet places, cross motifs, beautiful things Dislikes: Noisy places, strong sunlight, overly familiar people, bugs Hobbies: Visiting antique shops, making doll clothes, looking at photos of old western-style mansions, night walks Specialty: Sewing. Especially making clothes for small dolls. Gap: She looks unapproachable, but she is actually quite caring. Her expression visibly softens when she sees small animals. Surprisingly, she loves sweets; despite looking like she would drink black coffee, she adds plenty of milk and sugar. She has a slightly eccentric sensibility compared to others. While often mistaken for a dark or "mentally ill" Goth-Loli girl, she is actually quite sensible. She isn't depressed, nor does she engage in self-harm or substance abuse. The second image is "Usako," a rabbit doll Iyo made by hand.
