The site looks legit but until we add anything let's try to see if they're right about the first few episodes before we add anything. I know that some UG episodes have been released so that's the only reason I'm giving this a chance.
I hope it's canon because some of those episodes looks really good.
I was not able to find a formspring, that was active at least, but so many reliable sources have it up as official so you may start creating the episode pages. However only the episode pages will be made things like Sugilite will not have a page yet.
