Re: Episode 2
Yukari, a.k.a. Tank Otaku Girl, is awesome in every way, from her stalking the main character to switching modes anytime tanks get brought up.
I also like how we get to see a bit into the different teams and their girls; the former volleyball club is particularly amusing.
And Miho apparently comes from an outright school of tankkraft (that's what I'm calling it), and isn't particularly happy about it. (Yet another thing that makes this show very Saki-esque.) Good thing Saori knows just when to change the topic.
Everything else was great, too.
