All I know is that it's more than likely made by the group Rush Rise Line, and I believe the name is Sora Ero Animation (but I can't be sure, since the title is a bit blurry at the end)
Google gives absolutely nothing
thats a preview of the new animation for rush rise line, the name is correct, its 80% done though so not released yet
