I also remember that we talked about how contradicting waiter's origins are if she were "just the demon". We know for a fact that the demon of pride didn't care for Riliane whatsoever (unlike the Demon of Sloth which had an obvious liking for Eve's appearance, Gallerian and possibly even Margarita) and Riliane didn't replace him either unlike Banica (unless there's something we don't know about pertaining Riliane's aftermath? Even if that was the case, then the problems that Servy brought up would still apply, though.) That makes waiter some sort of mysterious character in all of these (well... Aren't all of them mysterious though?)

As far as we know, there is no Hansel in the Story of Evil. I mean, if there is a reincarnation, it does not come up during the events of the DoE. And Blood Stained Switch happens in a different period than the whole chronicles as far as I am aware (?), so I think Mayu isn't related to Elluka and Irina at all.
