Ugh...they're gonna get bigger!

- Overall, a body type that's pretty easy to scoop up.
- She's self-conscious about her chest and wishes it were as big as Mei's.
- She's usually pretty sensible, but around Mei, she can let herself go and show her selfish side.
- She always pushes doing tasks to the last minute and ends up crying to Mei about it.
-The type to say yes to every sexual request. Maybe because she's insecure.[Big-chested Sweet Dom - Mei Sano] CV: Yuka Hinata
