I read some spoilers on a Japanese 2chan thread that has since been archived. Maybe a possibility that they were making shit up, but I will write some out.
Spoiler for Some people might not want to be spoiled before reading, short story just released in Japan:

Some comedic mention of Haborym giving Yuuji homework (he wanted to train Yuuji in military tactics)
Yuuji has revived Dragon Tail and Tyrant, something about there being an army of Rinne within Tyrant (stored like Shana's Yogasa)?
Brothers of the Maccabee are now Yuuji's minions, but understandably they aren't as good as Bal Masque
Barometz is an oldtimer Denizen (ie from Earth)
As for the story's time period, one person thinks it has been 2 years since Shana/Yuuji stopped wearing school uniforms. I think in Hope, Yuuji said they would wear uniforms until old enough to graduate.
