From your perspective then, because there are only 23 players, then there should be 26 characters there including your character. Given that we know there are 15 species, and we also know that Witches and Dragons cannot be fake claims, that means one of the species groups with multiple characters must include a fake character, right? So I went through this earlier:
So the only two groups that have more that one representing are Vampires and Espers. Logicially, then, it means that if there is a Vampire fake claim, it must be Krul Tepes. And because of the existance of Nao being in Prof's wincon, the Esper fake claim must be Rimi Sakihata. Do you see the possible issue I may have here, X? I have every reason to assume that both are in the game.
