raine sage
A protagonist from Tales of Symphonia, Refill is a half-elf and Genis Sage's older sister. Refill is the professor at Iselia's school, and is Lloyd, Collet, and Genius's teacher. The calm and collected "Professor" helps the party with her healing and buffing spells. Just don't let her near any ruins. Or supper.
Her name in the Japanese version is Refill Sage.
