Strike Witches 2 is a perfect sequel. It takes what the first season did and improves on it from front to back, with better writing, more emphasis on the characters being awesome (as opposed to just sort of being there as they were sometimes in S1), and a whole lot more memorable events. I can’t remember much about the first season—I enjoyed the characters (mostly for their designs) and the general premise, but there hadn’t been anything in the show that really stuck with me, which is why even though I felt myself being instinctively defensive of it, I could never say that much good about it.
2 cures that entirely. Almost every single episode is memorable for one reason or another, and the series is riddled with moments of ultimate badassery. Being as “moments of ultimate badassery” are always my favorite part of anime, this meant a lot to love for me. Besides that, it got rid of other things I didn’t like about the first series, like all the in-fighting that came from Perrine (this time, she’s as much of a lovable character as the rest), and general lack of presence from others (everyone gets their moment in S2, and none of those moments are throw-away.)
There’s definitely more than one moment of awesome worth highlighting here, so I’ll just pull all the biggest ones.
