That was a great episode. After seeing what makes her tick, I like Kona/Frau more than ever now, and Kai proves to actually have a heart and care about something, for once. Also, I smile every time Frau goes "duhuhu".
Really looking forward to the next episode too, if it focuses on Airi. That was kind of hinted at earlier, and it has the potential to be really interesting (the real world/virtual world divide, etc.)
I'm still rooting for Akiho, though...
