Alisa is resolute and self-assertive, as well as being a brash and impulsive young woman. She is capable of holding a grudges for a long time. Alisa also gets easily flustered by unexpected events, and gets noticeably upset when asked to room with boys, or when members of her family show up unexpectedly. Despite all this, Alisa tries her best to make her friends happy, and even if she denies it initially, cares deeply for all of them.
She is the only daughter of the Reinford family, owners of the Reinford Group. Alisa herself states that, when her father was alive, she and her family were genuinely happy. Her father passed away when she was 9, which left her in the care of her maternal grandfather, Gwyn Reinford; her mother, Irina; and the family maid, Sharon Kreuger. Following her father's death, Irina began losing herself in running the business, and Alisa's family life quickly fell part.
During the Nord Highlands field study, Alisa states that she was treated poorly by the other kids, due to her status as heiress of Reinford Group. As such, she did not have many opportunities to make friends.
Thors Military Academy
In an attempt to distance herself from her overbearing mother, she enrolls at Thors Military Academy. She becomes an unfortunate acquaintance of Rean Schwarzer after the incident at the Old Schoolhouse, and although she despises him for it, she reluctantly apologises to Rean for how she had been treating him the first few weeks of their acquaintance. Alisa reveals that she had been trying to apologise to Rean since then, but hadn't been able to.
While in the Nord Highlands, she confides in Rean that she misses her old family and yearns for the past. She expressed concern that the company had become more important to her mother than family ties. When Alisa reveals that the railway guns were manufactured by Reinford Group, she states that both her mother and the company had crossed a line. She also says that she has no regrets about joining Class VII, as she feels that the experience has let her grow as a person. Rean and others come to learn that despite everything that has happened regarding her mother, Alisa cares deeply for her family and friends.
She has a sisterly relationship with Sharon, who enjoys teasing Alisa and getting rises out of her. She is also close with her grandfather, Gwyn, although she felt betrayed by his supposed abandonment of her and the Reinford Group.
Aftermath of the Civil War
After the Erebonian Civil War, Alisa went back to Thors Military Academy to hastily complete her education. She also gets into a relationship with Rean who is still suffering from Crow Armbrust's death and the revelations about his father (if the player chose Alisa as Rean's partner) and helps him slightly recover. However, due to feeling a great sense of responsibility and duty to her family, Alisa decides to leave Thors to help her family rebuild the Reinford Group.
Within the Reinford Group, Alisa takes up the duties as senior manager. She is responsible for the ARCUS II and the division dedicated to orbal staffs. Alisa also serves as the liaison between the Thors Military Academy and the Epstein Foundation.
