Anime has an incredible way of subverting expectations. Some series look simple on the surface but turn out to be deeply emotional, thought-provoking, or even life-changing. Too often, people judge anime by its art style, title, or genre and miss out on stories that leave a lasting impact. Whether it is an adventure wrapped in unexpected darkness, a romance that transcends its tropes, or a mystery that keeps viewers on edge, there are many anime series that prove fans should never judge a book by its cover.

Despite there being countless anime in existence, there are a select few series that are unexpectedly good hidden gems. From mind-bending sci-fi to heartbreaking dramas and epic sagas, there are many anime that will leave fans shocked in the best way possible and give people new favorites to enjoy.

The irony is that the show itself is about breaking free from stereotypes, making its misjudgments even more unfortunate.
