Story of: Dragon Ball, this Son Gohan is too amazing!

[No system][No melodrama][Not brainless][Refreshing story] Travel through a desperate future world and become Son Gohan with one arm and a scar on his face. It looks like a hellish start, but Son Gohan, who crawled out of his grave, was grinning. Oh, despair? Look at me defeating all the bosses while chatting and laughing, and reaching the top of the universe. What? System? What do I need a system for if I'm Son Gohan?
