10 Best Seinen Anime, Officially Ranked

The Seinen and Shonen shows are the most popular anime categories, comprising the top drawer series in the anime universe. While the former focuses on attracting young male audiences, the latter keeps its sharp focus on creating content that appeals to the hearts of young adult males from around eighteen to forty or forty-five years of age. Keeping the show in a Seinen category, the anime mostly deals with more mature subjects rather than adventures and superpowers, which tug at the heartstrings of the young generation.
