I'll amend two of these...
Pre-Coma Kuroda = Rum
or
Post-Coma Kuroda = Rum
and
Post-Coma Kuroda = Papa Akai
As I see it, if Asaka is Rum, Hyoue is not Rum.
What are all of the current big fan theories? Both the more obvious ones to conclude and the ones that take a bit of reaching.
the ones I can remember are:
Asaka = Rum
Mary = Asaka
Wasaka Rumi = Asaka
Kuroda = Rum
Kuroda = Papa Akai
Papa Akai = Rum
