I finally fixed it. I left Kelly with Dear at the tavern. Left the tavern, saved the game, went back in and retrieved her from Dear and when I made her the main character it was her original sprite.
Hello, I am having trouble with my drakebold sprite, I have been using the broken dagger and the dagger hasn't had any problems until I went into a siege and Mugen was on the enemy side. After killing him last on the third round Kelly now looks like him now and I can't revert her back.
