There's going to be a On Her Majesty's Secret Service ending where Denji manages to save Asa and seperate her from Yoru, and the two confess their love for eachother, and then when everyone (Shigger included) is having a lovely time at the school festival, Conquest³ shows up and blows Asa's head off or something. And then maybe the world ends, I don't know. Other scholars have convinced me there will be dire consequences for Denji by the end.
