What happened to Mon-chan after the 2000 event, is he this guy here in pic?

And so based on the final reveal of who friend is in the last chapter, are we to assume that Katsumada's death was just a hoax, and he was just some poor boy even worse off than Sadakiyo who was bullied and ignored to the point that no one noticed he even existed?
