Vivi loves to play (naughty) pranks on people, especially her older twin sister Linde. She abuses her identical appearance to present herself as Linde and put her sister into awkward situations. Rean Schwarzer becomes a regular target of her pranks as well.
Erebonian Civil War
As soon as Trista is being invaded during the start of the Erebonian Civil War, Vivi's fear overtakes her playfulness and heavily relies on her sister during their escape from the Academy.
After the outbreak of the Civil War, Vivi flees to Legram. There Sister Theramis tried to calm her down by listening to her worries about not having her sister around. Her superior, Father Hamilcar, succeeded in doing so and even managed to motivate her to help out around the church, impressing both him and Sister Theramis with her capabilities.
Once she boards the Courageous during the Civil War, Vivi takes up the role of observer and self-proclaimed "Sexiness Officer". During her time on board, she discovers that she's a natural at observing and expresses her interest in keeping track of "naughty escapades" throughout Erebonia.
After graduating from Thors Military Academy, Vivi put her observing skills to practice as a journalist/photographer.
