Sayaka cuts off the firstNalakuvera's legs with her sword, using its default defensive barrier to act as an infinitely sharp blade. Then Kojou uses Regulus Aurum to smash the robot a dozen floors down into the subfloat. And this still isn't enough to kill it.
Yukina duels Christoph Gardos and wins by severing his hand. Earlier, she fought him with her bare hands and still managed an overall stalemate before Yaze throws her spear to her. From easily a mile away.
Christoph Gardos pulls a fast one on Dimitrie Vatler with the rest of the Nalakuvera fleet and the command robot.
Kojou sucks Sayaka's blood and activates Al-Nasl Minium in order to clear a path out of the subfloat they're trapped in. This ends up tearing an even bigger hole through it, although the thing was probably damaged beyond repair already.
Vatler defeating Gigliora Ghirardi and Broodt Dumblegraff, two Prison Barrier inmates literally too dangerous to be contained in any other prison on the planet, like it was the easiest thing in the world. Becomes even more impressive when you consider that Broodt is a Dragon Slayer and can therefore easily kill his snake/Dragon familiars, but Vatler still overwhelms him.
