She is renowned as the greatest mage on the continent and one of the heroes of humanity.
It is largely unknown of her background as Celica has forgotten her memories prior to the 400 years, beside her involvement in the Fengumi War that occurred 40 years prior to the series and being was part of the "The Six Heroes".
Some point after the war, she joined the Alzano Empire's Imperial Court Mage Corps, where she adopted a young boy named Glenn Radars who she took him under her wing and taught him the magic.

Celica is a wise and intelligent woman who can be playful at times but behaves according to the situation. She cares deeply for Glenn, worried about his welfare as she recommended him as the new substitute teacher for class 2 and to the point of putting her reputation at stake. She has built a big reputation at the Alzano Magic Imperial Academy as well as throughout the country. She likes to often tease Glenn with her antics causing him to feel embarrassed, but is very supportive of Glenn and his students and is willing to do anything for her loved ones. She is also a determined and stubborn person as she wants to finish the labyrinth to see what her identity is. She has been stubborn in this matter forcing herself through all her obstacles and not listening anyone including Glenn.
Celica is weak when it comes to physical power due to her tender muscles. But it still unknown whether or not she is able to use the military hand to hand combat.

The mithril sword is alchemy type sword that was previously owned by her late friend who was a hero of humanity called "Sword Princess" during the Magical War. Celica activates the spell called "Altenate Black Magic [Load Experience]"(黒魔改【ロード・エクスペリエンス】) to temporarily make up for her lack of fighting skills by "loading" battle memories of any weapon's possessor that resides in those weapons, it makes her temporary unstoppable in swordplay if she were to cast this spell. While these feats are easy for her, it does consume a lot of mana and she can only uses them a few times if her magical capacities deteriorates in any way.

Celica suggested him to teach at the academy as a substitute teacher which Glenn denied immediately stating that he was not fit for the job, which Celica agreed that he didn't have a teacher's license. Glenn asked her to stop forcing reality into someone who acting cool, where Celica stated that he doesn't have a choice but to accept this offer.
Glenn questioned, if he rebelled about that where Celica threatened him whether he preferred to be struck by lightning, or be burned in a fire or be frozen in ice causing Glenn to fall at her feet pleading her to support him. Celica smiled at him and starts chanting the spell "Extinction Ray" causing a a thing ray of light which annihilated a part of the building. Glenn changed his mind, when Celica threatened him that the next one won't miss.
