Once a grand mage recognized as the Sumeru Academia's most distinguished graduate in 200 years, Lisa has since returned to Mondstadt to become the humble Librarian of the Knights of Favonius. She is an intellectual witch who can never get enough naps. As the Librarian of the Knights of Favonius, Lisa is smart in that she always knows exactly what to do with whatever troubles her. As much as she loves her sleep, she still manages to keep everything under control in a calm, composed manner. Lisa is a proficient witch; as such, she enjoys everything related to the elements and items that would help her in her understanding in them. Despite her position as Librarian, Lisa takes it somewhat haphazardly as she appears to be relatively bored dealing with the normal books, instead preferring those in the restricted section. She still takes the job seriously nonetheless, as she will personally go out to collect books that are overdue, albeit in a way that she can still enjoy the smaller things in life. When Lisa becomes angered, the surrounding air becomes electrified in part due to her Electro Vision. This generally occurs whenever someone doesn't return one of the borrowed books on time, or if they are damaged or stolen. Reflecting her favorite flower, a motif of roses is present throughout her outfit.
