Oh, my.
Miku: Kya! Mei-chan, something's wrong!
MEI: It's early in the morning. What's wrong, Miku... Oh, pardon me, who is this?
Miku:: Not "who is this"! When I woke up, Rin-chan became big breasted!
MEI: Hyaah! She sure has grown really quickly~!
Miku: That's not the problem! Mei-chan, she's larger than you! What do we do?
MEI: W... what do we do, you say....
Rin: I'm hungry~
MEI: Well anyway, let's have breakfast first. Then we'll think about things afterwards!
