There was the part where Ryu cleared the whole bridge and carried Bell across with her attack. It'd come down to whether destroying the bridge was critical to killing the monsters, or whether Ryu's attack would have wiped them out anyway. I can't be sure.

What I do feel however, is that the intelligence and power level of the Deep Floor monsters have taken a nosedive.

Now they're dying in one swipe, the attacks don't really phase the two anymore, they get tricked by a cloak and smell.. they're just back to fodder again when just a few episodes ago each encounter felt like a miniboss.
