On what story is 'The Watcher' based?

Naruto, but Naruto isn't the MC, Its Choji's twin brother that has a system. As much as I wish for Chojusen to be a space-trotting gopnik, we probably won’t ever see that come to fruition. This is the closest I can come to photoshopping an image that resembles Chojusen. He’s supposed to have parted hair like a comb-over. But, aside from that, the image is pretty much ok.
