Elise Schwarzer is the sister of Rean, and is a supporting character in the Cold Steel arc. The daughter of Baron Schwarzer, she was an only child until her parents adopted Rean into the family. She grew up with a fondness for him, which only grew more and more with each passing year. She enrolled at a girl's academy in Heimdallr, whereas her brother enrolled at Thors. However, they do send letters between each other on a routine. Elise is a softspoken, yet kind person, with a deep care for Rean and his wellbeing. She is assertive when he isn't taking care of himself or when he is acting rash, but doesn't take it well when he talks back. 

Elise has a higher, softspoken voice. She should sound more gentle, as she is not a very loud individual. Her emotions usually will have her being upset, flustered, reminiscent, and formal.
