This is a world where you can randomly select a substitute when you become an adult. However, because there is no animation like JOJO in this world, many people have awakened and are curious about the substitute, but do not know how to use it. They also think that the substitute is a waste. And Yu Xin is one of them. He has awakened the "world" because he is a time traveler and knows the abilities of this substitute well. Does he want to be like Dio and have the ambition to rule the world?
