OK maybe I should do an AU checklist, for posterity if nothing else. SORT OF UMINEKO SPOILERS. But it's a fictionalized interpretation of things so don't think this AU is something that actually happens in canon or anything, in the way that it's presented here. The short version is Beato's AU is a classy androgynous dude named Lion who looks similar enough to Beatrice to be identifiable to people who know her well, but different enough that it probably takes some head-tilting.
( ...BUT YEAH IT'S PRETTY UMINEKO SPOILERS NEVERTHELESS. )
I think I made it to the point where actually there are so many differences that I don't know which differences to list orz QUESTIONS CAN BE FIELDED HERE IF THERE ARE ANY MORE OBVIOUS ONES I FORGOT
