Yoyo is Mashiro's grandmother and one of Sky Land's most respected scholars. She's picked up knowledge on just about everything over the years, though she's not the type to hand it over freely. True to form, she keeps things close to the chest, doling out information only when she figures the timing is right. It's the kind of personality you'd expect from someone with her experience—measured, deliberate, and always thinking a few steps ahead.
