It's a gif, the end of the OVA of HyperDimension Neptunia the Animation.
The OVA was originally going to be jap exclusive, but made its way around. This is pretty much Rebirth 3 stuff, but nothing exactly spoiler.
Thanks for the info! Was mostly surprised because the chars all look related. But didn't ask about that, specifically to avoid spoilers. And the art-style is quite pleasant!
