A Stand-In Messenger in a Crossover Anime World

My name is Xiao Yi, an ordinary person who somehow ended up in an anime world and somehow gained a Stand. But I was thinking, in a crossover anime world, there may not even be any danger, and I do not need to save the world, so what use is a Stand to me? The beginning may have a bit of black history, and it is not written very well, but it starts to really pick up from the later chapters.
