Puma Noro's Wonderful Journey in Terra

My name is Jonny Joestar, I used to be a horse racer and now I'm a Casimir country veterinarian. Everything in the other world is a thing of the past to me. Now I just want a peaceful life. What! ? What does it mean that I owe millions in debt and have to go to a knight competition to pay off the money? What does it mean that a person who is a champion but is framed and infected does not deserve to be awarded a medal? "Damn world, slap my dark mental teeth!" This is a story about JOJO and the world going from negative numbers to zero.
