To start with:

The Story So Far: Having gotten all the information they needed out of Godel, Negi and his team attempt to pull out, just as Fate and Cosmo Entelecheia make a big attack, armed with a huge demon army, and a giant Lovecraftian (or at least tentacled) horror. They seem to be immune to the attacks of MM natives, and worse yet, have artifacts that can reduce people from the Magic World to nothing more than petals blowing in the wind. Several of our heroes' friends have already been seemingly killed, even Jack Rakan (though he still managed to come back long enough to smack some sense into Negi, and tell him the Asuna they're with is a fake.

Having seen both Craig and Aisha fall defending her, Nodoka puts the tricks they've taught her to good use, turning the tables on one of Cosmo Entelecheia's mages, and finding out how their artifacts work. She makes her way back to one of the separated groups, and tells them what they need to do to not only stop this, but possibly get back all the people lost to the attack.

Chapter 281 Spoilers: Yue and the remaining Knights go on the offensive, Haruna battles Kaijuthullu, and Chachamaru's artifact is a laser pointer... connected to a satellite cannon.

Akumatsu is officially trying to give Nanoha a run for her money. mrgreen

And it seems Yue may finally be getting her memories back.
