It hadn't happened for a while, so you might have missed it: "Academy Blues, side stories" has one more chapter.

yup.I missed it for one whole day. This side story is abit heavier than the usual, especially towards the end. Hope the next AB chapter comes out soon. >.<
Here we see that Hayate is, like Nanoha, scary when pissed, even without raising her voice.
I really liked that chapter. a little dark, but the concept was awesome.
