The cash item twist was bullshit. The fight could've worked without all that. When he switched to the bow, he could have sniped Shaltear til her HP dropped to crap then nuked her with Fallen Down (Sora no Otoshimono song!). The axe and shield parts were pointless.

It's also annoying how Shaltear forgot all about her betrayal. I would've loved seeing her in full guilty state.

That said, there should be a 2nd season for this. Every atom of this show is just an excuse for badassery, and that's not a bad thing.
