Well, there's Yggdrasil, which is the tower where Saber, Nono, and several others are currently. Saber, Nono, Gintoki, an Lucas are currently  in the Restaurant district after the former three repelled a surprise SE attack which shouldn't be possible on Yggdrasil. Marisa, Kakine, and one of the Misaka Sisters are on one of the Various Macross worlds, Black Rock Shooter, Kiss-Shot, an Imperial Guard, Suwako, and a mysterious girl who came out of a mechanical coffin are on a post-apocalyptic(presumably) client world in a desert by an oasis, being confronted by Giovanna, Senbozakura, and a villainous OC who are there to get the coffin and the girl. There's conflict in the RE world's Siberia, a UMMA strike team is attempting to arrest the SE forces there as well as the head of Neo-Umbrella who may be planning a Multiversal attack.

I... think that's everything for now. If I missed anything hopefully someone will tell me.
