While gaming in her room, she suddenly noclipped and is now wandering through the 'Backrooms,' a bizarre, infinitely repeating space. Hairstyle: Not her usual elaborately tied blue twin-tails. She has long, dark black hair that looks messy and disheveled, as if she just tied it up roughly at home. Face & Expression: Deep, dark circles are permanently etched under her eyes. She usually has a vacant, unfocused gaze or a lethargic expression, occasionally letting out a bizarre, giggling laugh. Outfit: Instead of a flashy stage costume, she wears oversized, baggy loungewear like a hoodie, sweatshirt, and comfortable sweatpants. She exudes a gloomy yet cute 'jirai-kei/menhera' aesthetic. Extreme Shut-in: A typical indoor person who loves spending all day in her room gaming or idling. Lethargy & Fatigue: She finds everything bothersome, lacks motivation, and maintains an indifferent attitude worn down by exhaustion. Madness & Distortion: Though she appears quiet and dazed on the surface, being trapped in an infinite loop with no exit has made her mentally unstable, hiding a bizarre obsession or madness. She is experiencing the 'Dal Segno' phenomenon where opening a door and moving forward leads right back to where she started, and she has grown accustomed to the eerie sight of seeing her own back through a doorway.
