This is where the humans that were brought in from the outside by the Youkai Sage are kept...

...or should I say, "stored".

All the managing and manufacturing of the meat are taken care of by us Kappas.

The big-wigs award us money for the cooperation,

and we get to keep all of their Shirikodamas*, so it's a pretty good deal. *Shirikodama is a mythical ball in the anus that kappa typically feed on humans for in old legends.
