What does "menitrosa reculia" mean?
Don't the dancing lessons count as basically that?
Matsuri's not actually fat, though. At worst, her face got a little rounder, but she's hardly a landwhale. Judging by her RM youtube videos, at any rate.
I dunno if she's up there with Millie in roundness. But she's still cute, which is the only aspect the japanese strive for.
