I think most of us are from other places than each other, honestly. Never heard of your Nekomamushi though. I'm from a planet called Earth but I seem to be from a different one than a few others. There seem to be a lot of us here from an "Earth".

Otherwise, you seem to have a good idea of what we're supposed to do. The books are more than books, really. More like their own little worlds. Why do you think it's a waste of energy?
