「夏休みとねことアジ」 (Natsuyasumi to Neko to Aji)
"Summer Vacation and Cat and Aji"

That wasn't exactly what I was expecting, but the episode as a whole really set in stone just how well behaved Tsumugi is. If anything, I hope that when I have a daughter (I will have a daughter), she'll be at least half as well behaved as an imaginary anime character.
