Queen of Hatred (O-01-04), also known as Magical Girl before Observation Level 3, is a WAW Class Abnormality that is capable of escaping and benefiting the facility.

The Queen of Hatred resembles a young, pale-skinned girl. She has large, yellow, stylized eyes and four-fingered hands. Her long hair has a pastel blue and purple gradient as coloration with two strands curled away in the shape of antenna. She wears white tights with pink accents, a pink, layered/pleated skirt, a pink shirt with white sleeves, and a large pink ribbon on her chest to match. She has two wing-like pieces on her shoulders and a pink and black heart clip in her hair. Beside her is a pink staff topped with a winged a star which has a heart-shaped hole at its center. Its grip is striped with yellow and pink, and the base is tipped with a pale blue heart with a pink star in the center.

When she breaches in a hostile manner, The Queen of Hatred will start to transform, floating into the air as multiple light blue spears impale her. Finally her staff will float above her and impale her, triggering her transformation. She takes on a new appearance, specifically a light-blue snake-like creature, with black, empty eye sockets, a pink lower jaw, a pink ribbon on her chest, a pair of big light-blue wings with purple and pink feathers, and arms coming out of the side of her head with purple hands. Her back and spine are decorated with several heart-shaped objects, with pink borders and a black interior.
