Yeah. If it was clearly not the original Gridman, I wouldn't have brought up fusing the pages, but I think there's a little too much evidence that this is the OG Gridman.

First, Anosillus the 2nd said in episode 6 that her predecessor owed a great debt to Gridman.

Second, there was the fact that the original Yume no Hero started playing as Gridman went back to his classic form.

And second, the theme song, UNION, pretty much describes the show. Now the final verse doesn't suggest that they form an alliance for now, but that they form an alliance just like they did back then.

Without this body of evidence, I would have treated the SSSS version of Gridman like he was the Seven 21 to the original Gridman's Ultraseven. But you really can't ignore this amount of evidence, you know?
