Five years ago, by gathering the power of Light and other chosen children, the vampire monster was defeated. It doesn't matter whether he will make a comeback, what's important is that everyone will have a peaceful time to live in peace of mind. The point is, are Daisuke and Xian just the best partners? It's really the biggest joke of the century. When they went to school together and spent the past ten years as childhood sweethearts, something was slowly brewing. Maybe it's very green now, a little bitter, a little sour and sweet. After their hardships are over, they will have a new life with their Digimon friends in the new Digital World and the Human World. When Digimon were in the human world openly, troubles followed one after another. After all, humans are the most troublesome creatures. Let's see how the once-chosen children grow up to compete with adults in a battle of wits and courage, and develop their own emotional paths.
