I was lazy and didn't really read it. Looking at it again, it's a stomach that surrounds everything, similar to a Bounded Field. Then it's actually Anti-Army?

Then it will digest everything there, but things made only out of prana are easier to digest, while normal humans will take longer, because enzymes and stuff. That is, if my interpretation is correct.

At first I thought it was something like Sacchin's Reality Marble that drains all the prana, but was useless on normal people because they don't need prana.
