I'm kind of disappointed Asumi didn't ask for a proper date.
When Mai said "Let's meet again!" I thought Asumi was gonna say that since she'll have to come all the way to Tokyo from wherever it is that she's living right now (I forgot) then they should make it a weekend date! Mai should take her to Mouse Land, and to the Tree (whatever the eff that is), and to all the big tourist spots in the capital -- and after enjoying their day together like that, they could spend the night at a nice hotel.
Sigh. Asumi's brain always short-circuits in important moments like this.
And btw I'm starting to get really, really tired of Ouka. No matter where they are — at the restaurant, at a museum, at the zoo looking at the cute and adorable pandas — all she thinks about and talks about is sex, sex, sex. You tell her "Sempai, look at the cuddly-wuddly pandas!" and she replies "Hurr hurr you sure sucked some titties yesterday huh? Hurr hurr!" After a while it gets more boring than watching paint dry.
The uninhibited and unrepressed act was kinda fun at first, but it got old quick.
