THIS!!! I support this so much!
I guess NakkixMaimi to me seems more plausible but sometimes I like NakkixAiri when I see them together.
Oh but then there was that Pucchi moni V performance when Mai was down during the DVD taping and it was just Erina and Nakki and I thought they looked good on stage together too. fufufu... when it's not TakaGaki, I'm fickle with my pairings.
