Refill Sage, known as Raine Sage, is the elder sister of Genis Sage and a teacher at Iselia’s school. Her calm, analytical nature masks a fervent passion for ancient ruins, which she prioritizes exploring during travels. Though protective of Genis, she enforces discipline through strict measures, including corporal punishment toward him and their childhood friend Lloyd Irving. Her notoriously inept culinary skills draw frequent criticism, provoking defensive retorts when questioned.

A half-elf born in Tethe’alla, she and Genis fled to Sylvarant as children to escape their homeland’s oppressive racial policies. Their parents orchestrated the relocation to safeguard them from persecution and prevent Raine’s exploitation by the Imperial Research Academy, which sought her prodigious intellect. A childhood boat accident left her with enduring hydrophobia, fueling her cautious avoidance of water.

In battle, she excels as a healer and support mage, wielding staves or rods to mend allies and amplify their strengths, though she commands potent light-elemental spells when necessary. Her arsenal includes the Crystal Rod, acquired through coliseum trials, and the Devil’s Arm “Heart of Chaos,” obtained by trading an ancient crown tied to fragmented memories.

Driven by scholarly rigor, she guides the group’s strategies with analyses of historical and magical mysteries encountered on their journey. While reserved, she occasionally deploys dry wit or sarcasm, particularly when her academic expertise or ruin-focused pursuits are challenged. Her mentorship of Lloyd and Genis intertwines familial duty with conflict resolution, balancing group dynamics.

Adaptations and spin-offs consistently portray her as a scholar-healer. Unused voice files in *Tales of Symphonia: Dawn of the New World* imply scrapped abilities like Heal and Fairy Circle, hinting at broader unrealized narrative or gameplay concepts. Her recurring gag weapon, the Deck Brush, humorously underscores her non-combat ineptitudes across multiple titles.
