Diana is serious, composed, and erudite. Being descended from a prestigious line of witches back to ancient times, she is exceptionally devoted to her magical studies and to the tradition and history of magic. Her status as Luna Nova's best student cannot be solely attributed to heredity — she has self-discipline and maturity far surpassing the average teenage girl.

She quickly becomes Akko's rival, though she doesn't see herself as her rival.
