Shonen anime tends to have some very specific hallmarks to identify it as a genre. Usually, a plucky protagonist and their friends are seeking some nebulous goal or another. Sometimes they want to be the best in their field, other times they're seeking an ancient artifact, and the list goes on from there. There are always some darker turns in their stories that tend to determine the changes that the characters will go through and, in the end, the stories are meant to be satisfying and fun without being too much like in seinen manga. But there is one thing that seems to tie a lot of shonen anime together.
