The best senen anime of the first season that you might have missed


When you say “shounen anime,” some of the biggest names in the anime world are likely to come to mind – current series like Attack on Titan or Demon Slayer, or older but still beloved titles like Fullmetal Alchemist and Naruto. These anime are popular for a reason; they’re excellent! And because of their popularity, they usually run for at least two, if not more, seasons. The other thing about these popular, great anime is that most people have already seen them if they like shounen anime. So while waiting for the next season of these huge titles, what else can you watch? In the shadow of some of the biggest names in shounen anime are other fantastic stories that sometimes get forgotten even though they also have good stories and memorable characters, too.

Just because an anime only runs for one season does not mean it doesn’t deserve love and attention, too. Usually it just means the anime was able to tell its entire story in 12 episodes. And sometimes, in our busy lives, that is exactly what we are looking for. These are our top recommendations for shounen anime that are only one season long (at the time of writing), and are still worth watching even if you have never heard of them before. All of these anime are shounen (aimed at young men, but in practice, loved by many different kinds of people), though they cross into other genres as well such as fantasy, comedy, and romance. They are all twelve episodes or less, so they were only on for one season. And they are all highly-rated and entertaining, so don’t let their short runs deceive you, or that you may have never heard of them.

Horimiya is an anime about two people that seem like they could not be any more opposite to one another, but are able to be more honest with each other than they are with anyone else. Kyouko Hori is beautiful, smart, and popular, but has little time to spend with friends due to the demands of her home life. On the flip side, Izumi Miyamura is covered in tattoos and piercings that make him look like a delinquent, when he is actually a nice guy. The two meet one another and the more they spend time together, the more they can actually be their true selves. Horimiya is a feel-good romance anime for shounen fans that like school settings.

One of the biggest benefits of watching a one-season anime is that you never have to worry about anything like boring filler episodes, or pointless side stories. You get all the benefits of a great shounen story, without any of the potential downsides of longer stories. Of course, there is also the disappointment of knowing that if you love one of these short anime, there may never be any more of it to watch, but at least the story is complete. Shounen anime are often cross-genre, and we tried to get a great variety on here so that there is something for everyone. All of these anime may have only lasted one season on the air, but it was a glorious season. And now, you have something new to watch while you wait for whatever is coming next from your favorite big titles!
