Demonio grew up playing soccer in the Italian suburbs as part of Team K, a group of kids united by one goal: making it to the nationals. When Kageyama—then going by Mr. K—came around, he basically made them an offer they couldn't refuse: join his team and the nationals were theirs. Before that, Demonio was pretty much obsessed with Fideo, but once he signed on with Team K, that admiration flipped. He started seeing himself as above everyone else, especially the rest of Orpheus.
