Wow my name is really lon wrote...
Do you know why the first season was delayed?
Seems like you've misunderstood my post. This is the first season.
I'm safely assuming that we will get a 2nd season IF what I said in the spoiler box were to come true. This season only has 12 episodes, and I don't think that's enough.
But there's the upcoming OVA. so who knows?
EDIT: I suggest people to not watch the ED sequence.. tooo many spoilers in it.
