Another Kamen Rider. Ren walked in, crossing his arms as he watched V3 fight. He wasn't quite sure how he was supposed to feel about the multiple Riders here, apparently none of them from the same world, but he supposed he had to be a little grateful that no one else from his world was here. It would have only made it that much harder to win the Rider Battle when the worlds were restored if they had to be allies here.

"Do they always make so much noise when they attack?" he asked, finally deciding to get the other Rider's attention.
