She's Mari's younger sister and a child prodigy whose Saviour powers manifested unusually early. Though technically she works as her aunt's assistant, she's really the one keeping everyone safe around campus. She's got this uncanny knowledge about basically everything, and she can even drive her aunt's car—which is pretty wild for a kid.
Her abilities are genuinely useful: she can heal injuries and cast something called "Field of Dreams," a spell that lets Saviours duel without actually hurting each other. It's the kind of power that makes her invaluable in situations where things get dangerous.
