it's the AU party
Megumi is doing what may have been a slight AU Decade rumor. A Fangire, Megumi is also pedo-Wataru's future wife, kyaaa~ Betrothed to him as soon as he was born, she doesn't really have any feelings for him in that way. And she uses Kivaara to henshin. What this means for attitude adjustment - she doesn't hate humans, but is not too fond of them. Expect a more trolly temperment.
Shinji - from his many AU's to pick from - is going to come from one of the 13 Rider Special endings. Aka as the ending where he becomes Kamen Rider Knight, destroys the entrance to the Mirror World, and maybe goes crazy in the end - seeing dead Riders and monsters in windows, mirrors, etc.
Ren isn't going AU.
