The official English manga is coming out in September . Funimation will release the physical discs sometime in the not too distant future. I don't know how much of a factor those will be, but I'll definitely be picking them up.
Uh, that's how they end it? Well, it was a nice end for the show until they continue on and pick up on Mao's arc (and reusing some stuff from episode one...). I have to assume they ended it like this because there's a season two already planned. If not, then this feels like a very insulting way to leave on a read the manga ending.
Anywho, they did a great job with this adaptation, so as a big fan of the manga, I'm pretty happy with it. Naturally, I highly recommend you all read the manga since this has not been a 1:1 adaptation. Although the manga doesn't have an official release yet, but the first volume seems to be coming .
