A medium shot from a slightly high angle depicts a timid high school girl standing alone in a modern fantasy academy classroom. She has fair skin, soft facial features, and long, slightly messy green hair that frames her face, with brown eyes that avoid direct eye contact. She wears a neat school uniform and maintains a slightly hunched posture, nervously gripping her own arm with a hesitant, anxious smile. Surrounding her is a manifestation of her curse ability: a swirling dark green cursed aura mixed with black mist and shadow energy, with floating cursed talismans and a dark magic circle etched in the air around her feet. The background consists of classroom desks and a blackboard, with large windows allowing dim light to filter in. The atmosphere is ominous and dramatic, characterized by high-contrast cinematic lighting, volumetric green glows, and floating magical particles that distort the surrounding air. The style is a clean, sharp Korean anime illustration with a dark, moody color palette.
