Sonia's a first-year high school student at the same school as Kana, and she's already way ahead of the curve—she qualified as a C-level healer through an overseas accelerated program while most kids her age are still figuring out basics. She's genuinely talented, but also pretty arrogant about it. Impatient too. She needs to be the best at whatever she's doing, and she's got this chip on her shoulder about proving that age doesn't matter when you've got real skill.
Her big goal? Surpassing Ria Karasuma's mastery of vocal healing. That's the dream she's chasing, partly to show everyone that a first-year can hang with the veterans if she's determined enough.
