The Best Anime Series of 2021
1. Demon Slayer (Kimetsu No Yaiba), a Shonen Anime Series
Largely hailed as one of the best anime of all time, Demon Slayer has been a hit in 2021. So popular is it that it had a massive movie release in major theaters all over the United States. With how few anime make it to theaters, this just goes to show how famous this anime is becoming.
It follows the story of Tanjiro Kamado, a teen who becomes a demon slayer after his family is brutally murdered. His sister is left as the only survivor. The twist to this story is that his sister, Nezuko, is now a demon who other slayers would like to put down.
Unlike other newly turned demons, however, she maintains her humanity as she fights alongside her brother. His goal? To find a cure.
You can currently watch Demon Slayer on Netflix, Crunchyroll, Hulu, and Funimation.
2. One Punch Man, the Best Anime Series for a Laugh
If you’re in the mood for an anime that makes fun of the typical superhero tropes, this is the best anime series for you. As a comedic series, it takes a look at some of the most common tropes, like mega-monsters coming into the city, and makes light of them.
The story follows Saitama, a young man who wants to be a hero. He sees a child in distress and steps in to help, but he’s unable to do as much as he wants. So, he starts training…and loses all of his hair. Now looking more like Master Roshi than an attractive young man, he’s able to defeat opponents with just a single punch.
With what some would say is minimal effort, he somehow became more powerful than any opponent. Watch as he looks for a reasonable opponent while growing bored with having no challenges because of his overwhelming strength.
Watch One Punch Man on Netflix, Hulu, Funimation, and Crunchyroll.
3. Cowboy Bebop, an Anime Making Its Own Genre
Cowboy Bebop is a science-fiction anime, but it’s not anything like Gundam or others in the genre. In fact, the anime tries to say that it’s creating a genre all of its own, and it’s not wrong.
Whether you like gun-slinging heroes or want to have a story of wayward bounty hunters looking to find where they belong, this is an anime that has it all.
The general story follows the male lead, Spike Spiegel, as well as Jet Black and Faye Valentine, as their lives collide while attempting to find answers. They work as bounty hunters to bring in cash. But each has their own distinct story, such as Spike trying to get back to his true love after fleeing the Syndicate or Jet looking for purpose after leaving a police force.

In Death Note, Light Yagami finds the “Death Note,” a notebook that belongs to Shinigami Ryuk. Ryuk, a somewhat clever and mischievous demon, decides to allow Light to keep the Death Note, as a way of occupying and entertaining himself.
After all, immortality can become boring for a Shinigami. So dropping a Death Note into the human world with simple instructions is sure to liven things up.
When Light writes the name of a person in the book, they will die shortly thereafter. If he includes a manner of death, that will also occur. Knowing this, Light starts out with good intentions, but he soon becomes obsessed with his God-like power.
Light takes on the alias “Kira.” Kira, however, is being tracked by an elite Japanese task force and detective, “L,” who is just as clever and ready to take down this serial killer.
