Looks like Tarako/uep20 did a remake of his very first video with Gumi and uploaded it to Youtube. The changes being the new Gumi model that he started using since his Deep Blue Town video, the camera work, a still image for credits, and (oddly enough) the fact that she actually gets embarrassed dropping her panties on stage. Honestly, I had completely forgotten that Gumi didn't even blush in his first vid.
