I was going to comment the same video because I was fangirling really hard after seeing that my girls Ran, Hina, Koharu and Mahiru were together (I need Juri in it tho, and I'm sure that Sumire and Laura are going to understand each other really quick) xD.

It has the confirmation of a Photokatsu song so I doubt its fake too.
