Demonology

My name is Naruto Uzumaki –well, I guess you actually already know that if you're reading this, haha… You probably know all about me – don't you?– or at least, you think you do. Do you know about my resident? Yep. Do you know who sealed the overgrown fur ball in my gut? Who am I kidding, you already know everything. Do you know that because him I can't mold chakra normally?
