Similar to JOJO fanfic, but the world view is created by the author himself. Among them, a lot of references are made to Jojo, and most of the inspiration comes from the Jojo series. If there is any similarity, it is purely imitation.
Here is the introduction to the feature film:
This is a world composed of realms and spirits. In this critical world, there are always people who have to stand up to protect the world. Most people who get this kind of supernatural power will fall into a long and inextricable excitement, but there will always be a group of people who will stand up and protect the world. These evil forces and these evil thoughts are all erased in the shadow of darkness, just like the oath of the shadow, allowing all darkness to be erased in the corner. But now, what should the aging shadow do? How can it continue to protect people in the shadow?
