Digital Illustration in the style of Ume Aoki, featuring a girl with long, black hair in two pigtails and black eyes, wearing a magical girl-style dress with drooping azure gauze sleeves and a white off-the-shoulder neckline, with an azure gauze mermaid-cut skirt over a white flared skirt. She holds a bloodied dagger in her hand, and her dress and hair are adorned with pearls and seashells. Her face is expressionless. She is in a parking lot at night, surrounded by corpses she has stabbed.
