Captain Rainbow - possible boxart

Reader Tom sent this in, and let me know that it comes from the depths of 2ch. You can never be too sure what is valid and what’s a prank when it stems from there, but would someone really take the time to make a fake Captain Rainbow boxart?! For those wondering, the text says, “”This is not really a game about a cool hero! If you want to know more, play it for yourself in a composed manner.”
