Well Zero's return and acceptance by the rest of the Order is really weak but nothing forgiveable.
The rest of the episode was incredibly fun though. Kallen getting used for fanservice again but seems like she'll shine again with next ep's battle. Chachamaru C.C. was a pleasant surprise and looks like she really likes hugging things.
Had a nice intro with Zino and Anya. Like the former but couldn't really get a feel of the latter. And just to clarify something, is Zino voiced by Hoshi, Kira's VA?
