Hmm what if he is like a timetraveller or dimensional traveller from a place where dungeons are already present- that would solve his lack of knowledge and the fact that he is unphased by monsters and dungeons. Also what if there is more than one player system and baby is from one of them and therefore you can't access his information since he's not registered into that certain system but another one
theory what if our white-haired baby face is actually a monster which came out from a dungeon I mean he doesn't necessarily have to be a monster but it's kinda sus how he doesn't know almost anything about this world like he was confused about the idea of live streaming and people watching them without actually physically being there
