I expected a lot more from the episode, but its problems pale before how terrible this arc was, and quite honestly the only positive thing remaining in this show is the fan-service (Seiri/Oriana) ... and Himegami
In short, what happened during these couple of months was a bunch of guys were looking for a sword, which was a cross, which turned to be person carrying, only she didn't, and then find a place, where they have an
epic battle, to utterly fail, but be saved by
coincidental fireworks 
Give a fucking break
