OH goodness how will they screw this one up? She misses a step, swings her pirate hook, and catches him in his other eye? On the other hand, if they pull it off, then we get a disaster hot springs arc instead. That's even funnier. You crazy kids, I'm rooting for you.
On the subject of this getting an anime. As much as I'd love to see it, I think getting this story past the censors would be an accomplishment. It's guaranteed to be a late-night slot or an ONA, unless they de-culturize it to an unfortunate degree. Those are all reasons it wouldn't get the budget or production quality it deserves.
