As in Kyrie's story, there is two "phases" of her life:

The younger Kyrie, before her academy burned down to ashes. A young, very intelligent fur but also a spoiled strict and demanding brat, extremely harsh with her students even if most of them are older than her, and cannot stand in front of failure. Often scolding students that didnt learned fast enough for her, she were known for being an alchemy prodigy but also the most hated teacher in the academy. Most of the people that surrounded her were only motivated by her worldwide fame and her impressive knowledge, being one of the few that atteined such skill in this discipline. She was also well-known for her fondness of high couture and such, often being the center of attention at events for her unique taste in luxury clothings. A little detail that is funny, she was around 16 at the time but never found any interest in love relationship, often calling them as "stupid breeding maneuvers only good for wild animals." some would call her just as cold as a rock.

The older Kyrie, after the incident, is when she went back to the forest. Wearing much more simpler clothes, her mental had many tradeoff: now a kind, gentle, often too romantic person, she grew shy and lacking much of self-confidence, a bit agoraphobic and very pilanthropist, to the point she can even sacrifice herself for the sake of one trespasser that is being punished and that Kyrie think is "unfair" for that person. She often regret how horrible she was before, but that doesn't matter much since most of the world thinks she died with the fire.
