Mori Calliope is depicted with long, straight pink hair reaching down to her lower back, and she wears a small black crown-like headpiece on her head. Her outfit consists of a form-fitting black dress with gold accents and a high slit on one side, revealing a red inner lining and parts of her legs. She wears a black, tattered cloak over the dress, with a hood that can be pulled up, and the interior of the cloak is also red. Her accessories include a chain belt with a red tassel, long black gloves with sheer brown sleeves attached, and black high-heeled shoes with gold details. The design includes a foldable scythe with a dark handle, pink accents, and a silver blade, stored on her back in a retracted form. Her overall color palette is a blend of dark tones, gold, and pinks, with muted reds and browns for contrast. Multiple angles and close-up details of her cloak, gloves, and weapon are presented to show the full scope of her design.
