It's not that there's no weapons- it's that you can't pick one up.

All of us that arrived here? We can't so much as grab a butterknife if it's with the intent to hurt someone. We could use pokemon sure- and well, they do normally use those, which makes it really easy to just sneak up on someone and knock them out if you ask me- but it's honestly just easier to be sneaky rather than violent.

The point is more that the world itself tends to lean...'PG-13', you could say. I mean we have background music for crying out loud!
