Man, I've danced with that last section with Hard Man, Gemini Man, and Snake Man about four or five times. Like this comment if you danced to any part of the song,too.
Just guessing, but this was probably made for Nicovideo, where they sometimes leave a space of a few minutes with nothing at the end of a vid (sometimes a static image and some BGM) because comments appear on screen during playback.
I watched this four years ago, and lost the link. I recently found a Jojo vid of this dance, and then I'm like "wait a minute this is familiar". Then I searched "Megaman" and "手描き", only to be greeted with the thumbs up sign as blue. Nostalgia time!
I know this sounds, really dumb, like *really* dumb, but this is one of the few things that makes me feel wanted someplace. I can't tell where that place is, but I know it exists, *somewhere* Man, I can get really mushy some days.
