Daughter of a distinguished lineage of magi, the Edelfelt, Luviagelita is their young and talented family head. As a student in the Clock Tower, the Mage's Association academy, she is one of the candidates for the position of student president for the current academic term.

She became acquainted with Rin Tohsaka after she began to study in the Clock Tower after the Fifth Holy Grail War. She finds in Rin a worthy rival due to their similarities; their encounters always result in fierce clashes. After a year together, a silent agreement was forged within the Department of Mineralogy of Clock Tower that "Tohsaka and Edelfelt must not attend classes together". The facade that she built for herself was withering away after a decade of use and her bad temper was already starting to appear, but after Rin showed up her daily life improved.

On a certain occasion, Luvia tried to reserve the 28th room in the top floor of the Norwich Students Dormitory entirely for herself, but that became impossible when Rin also asked for the same room. After a series of events that resulted in the recommendation letter that Rin got from a Lord being torn apart, a big fight broke out and a reception desk was destroyed in the process. Afterwards, both were forbidden from ever entering the dormitory again. So because boarding houses are too small, she bought a European-style mansion for herself to live in.
