One Sword Seals the Demon

I'm a demon, so what, I don't want to cause trouble, but trouble comes to me, sorry, come and talk to my sword, it will tell you my attitude. Don't worry, I won't kill you, just stay an ordinary person for the rest of your life. Well, that's probably it. I can't control accidental injuries.
