Another one of the trope's many attempts at fanservice, anime shirtless scenes provide viewers with more than just visual stimulation. Many series, regardless of the topic at hand, add in an unnecessary anime shirtless scene as a means to appeal to new viewers. Anime's charm lies in its visuals, and animators strive to ensure it appeals in more ways than one. As a result, shirtless fan service in anime appears in all manner of series, even if it doesn't necessarily apply to the plot at hand. While you expect aggressively sexual anime to show some skin, you definitely did not foresee shows about the undead to depict the human body as more than just zombie food.
In the end, shirtless fan service in anime remains as prevalent as nosebleeds and after school clubs. The series below may not revolve around suggestive topics, but they most certainly did not forget about suggestive content either. Shirtless women, men, and nonbinary characters show off their chests and abs with a complete disregard of storyline and self-consciousness.
