World of DanMachi

A young human woman with long, waist-length blue hair and light green eyes. She wears a black, form-fitting long sleeve dress with a collar and a yellow tie around her neck, reaching down to her ankles, paired with calf-high brown boots. She carries a staff called Holy Crystal Rod.

Cassandra has a timid personality, which leads her to act and move nervously. Because of this, she often relies on Daphne, who takes care of her. She displays a submissive attitude and tends to obey Daphne's orders even if she disagrees. However, she still stands firm on certain decisions, refusing to give in no matter her friend's insistence. She possesses an aloof air and a childlike innocence that is denoted in her eyes. She also has the ability to see visions, however, no one ever believes her despite her attempts to convince them. Nonetheless, she herself has a blind faith in her prophecies.

Cassandra was a sheltered girl who received a high-class education. At some point, Apollo took interest in her and pursued her until she finally joined his Familia. In the Apollo Familia, she became friends with Daphne and later followed Daphne to join the Miach Familia where she remains to this day.
