Elise Schwarzer is the youngest daughter of Teo Schwarzer and Lucia Schwarzer.
When Elise was younger, she and her brother Rean were attacked by a monster in the Ymir Valley. In that desperate situation, an unknown power overwhelmed Rean and he viciously murdered the monster. After the incident, Elise noticed that her brother had started to distance himself from the family, and so she sought to train herself to become stronger.
In S.1203, Elise left to attend St. Astraia Girls' School in Heimdallr. Although she had other reasons, such as preparing for her debut into high society, her main reason for attending St. Astraia was to free Rean from the guilt he felt over the monster attack.
Post-Erebonian Civil War
After the Erebonian Civil War, Elise graduated into the high school of St. Astraia Girls' School and was elected student council president. The close distance between Leeves and Heimdallr allows her to stay in touch with her adoptive brother, Rean Schwarzer. She also continued to support her best friend, Alfin Reise Arnor.
Elise is a well-mannered young lady who seeks to better herself. While aware of her social standing, she treats everybody like they are equals and cares deeply about people.
She worries greatly about her adoptive older brother and it is implied by Alfin that Elise has a crush on him. She is also friends with Princess Alfin, even though Alfin's teasing and pranks do tend to get on her nerves. She seems to be familiar with Musse Egret, one of her brother's students at Thors Branch Campus.
