Aries

Aries is very shy and polite. She frequently apologizes (sumimasen/Gomen'nasai), regardless of whether or not she is truly at fault. Still, she is very sweet and able to appreciate how kind of an owner Lucy is. She is quite easily frightened. Despite this, she is very obedient and willing to fight for her owner.

Aries is a female spirit who resembles a young woman with pink hair, brown eyes and a pair of twisted horns on her head. She wears clothes that have a white and fluffy wool-like getup. Her outfit changes, however, as the story progresses. In her very first appearance, Aries did not have a satchel on her waist.
