Runie is a confirmed
. Specifically, she is at least 32 or thereabouts. She mentioned in the last stream that her mom and grandma married at 16, and that she's twice that:
There's a decent chance that she's the oldest one in Phase, since there's at least one talent older than Airi, as some of the girls have alluded to.
Could someone please step up and save these girls' eggs?!
EDIT: Watching it again, she backtracked a bit on the math, so maybe 30-31, certainly enough for someone to think that 16 is half their age...In any case, her anime taste betrays her age
