As Anyone00 said, they'll be distributing it for free during the summer with the intent of hyping sales. It's a one-shot, 50 minute OVA. Crunchyroll's ended up with a few shorter things like this before, so it's at least not impossible that it could find its way onto there.
A random thought for the day: I know the OVA is supposed to be dead compared to the past and the 90s, but there's some pretty decent stuff that's come to video in spite of the industry's issues. I look at Katanagatari and how Gundam Unicorn is out there, I see an actual movie series for Break Blade instead of a TV series, I see the seven films of Kara no Kyoukai in recent years, and then there's the Tales of Symphonia OVA and the fact that the shonen action OVA Saint Seiya: The Lost Canvas has done well enough to get a second batch of 13 episodes approved. Beyond that we have a show like Gotchicmade coming along after years of waiting, and for this season we have no fewer than three shows aiming for an older audience with Rainbow, House of Five Leaves, and Yojo-Han Shinwa Taieki. I tend to think that things could be much worse if this stuff can manage to get made at a time when things are tough for the industry compared to the recent past.
Of course, the trick is how much of this stuff actually gets to us in the end as opposed to really otaku-centric shows and obvious smart picks. But there's stuff out there for the getting that could do well, that much is sure.
My top two hopes for TV series are probably Senko no Night Raid and Heroman. If those live up to the promise that I think they have, that's at least 4 to 5 series of serious quality from this season already.
