Celica A. Mercury

Celica is a young woman with long, brown hair tied into a ponytail with a red ribbon, and bright red eyes. She is a kind, generous, and sociable person who deeply loves her sister and friends. She is a sentimental individual who maintains a firm stance that all life is precious and will use her healing magic to assist those in need of it, regardless of who or what they are. She is also shown to be selfless to the point that she will shield a person with her own body without any hesitation. She develops affection toward Bloodedge as time goes by and seems to idolize him. She had difficulty interacting with Kazuma Kuvaru due to the uneasy feelings his presence evoked within her. It has also been noted by people (particularly Bloodedge) that she has no sense of direction, which usually ends with her getting lost.
