Lisa is a decently tall young woman, standing at 5'7. She has an athletic build with dark blue eyes and black hair, streaked with blue highlights, that reaches down past her shoulders. She has a melancholic sense of fashion, often wearing dark clothing and beanies.
Once an upbeat and happy young woman with a wide social circle, Lisa quickly changed after the death of her mother and the presumed death of Atticus. She developed a somber and quite bitter personality, quick to snap and put others down. Showing a general distrust of people, she easily slammed Savannah Whitesmith's story down as false and seeking attention. Due to hating angels due to their role in the Great War, she is very proud of her species and shows prejudice against a Nephilim man due to his heritage.
Lisa Fiss was born on Plutonis 27th, 300 TP to a lower-class family in Port City, where they lived in rented and shared properties. When she was around six years old, her father managed to get a job in Silivia and the family moved there, managing to improve upon their luck and finally buy a house. Growing up in Silivia, she became used to its customs and began performing well in school, getting above-average grades. This trend continued until high school, where she met Atticus Anoethite, the adopted son of the mayor Theo Rosington, and his friend, Jordan Walesh.
After a few years, their relationships became strained when Atticus decided to leave the city with a new group of friends to hunt demons, despite Lisa and Jordan's advice. Eventually, the group would be found dead on the outskirts of town, with Atticus' body never retrieved.
Mourning her ex-boyfriend, Lisa attempted to move on by leaving everything in the past, using her grades to apply to higher education courses.
