Reluctant Demon Lord

You are the big bad villain, or your were. You got tired of all that maniacal laughing and brooding in a tower that never got any goddamn sunlight. So you ditched it, the evil minions, the throne, the armies, even your terrifying dark armor. You left it all packed a bag and left. So now the demon lord is going to live a peaceful quiet life and god help anyone who tries to stop you. Updated now that I know more about Ai dungeon, and given a nice cover pic. (Note: the second time it asks for a name, it's a bug. I literally can't get rid of it, even though it doesn't exist in the story. Blame Ai Dungeon, I spent hours trying to get it to stop)
