The second and final volume of the anthology came out today. I liked it better than the first one, especially since a couple of the stories take place between Chapter 44 and 45 of the main series, and one of them was done by Nakatani herself.
Ah, yes, YagaKimi Chapter 44, and Yuu's never-to-be-forgotten "So, Touko-senpai, you ready to go again?" expression . . .
