List Rules Vote up the obscure anime you'll be checking out next.

There's nothing wrong with loving popular anime. After all, a lot of it is popular for good reason. That said, sometimes it's nice to branch out a bit, and try out some great non-mainstream anime instead. Yes, you can still enjoy Tokyo Ghoul and Sword Art Online, but if you're hungry for something else, perhaps try expanding your horizons. There's good anime no one has seen out there, and not all of it can be found on Crunchyroll.

The best obscure anime come from all genres. Are you in the mood for a slice of life anime about a high school music club that isn't K-On? Try Tari Tari. What about an emotionally wrenching seinen thriller about a group of boys in a juvenile detention center? Rainbow: Nisha Rokubou no Shichinin is a great choice. Do you want to watch a robot try to become an idol? Try Miss Monochrome.

There are great under-the-radar anime for every taste and preference. If you want to see some good anime not a lot of people have seen, check out this list. Who knows, you might even find a new favorite

Do you like Black Butler, but wish it had more vampires? Are you a fan of the seven deadly sins motif, but you've already seen Fullmetal Alchemist 47 times? If you answered yes to any of these questions, the often overlooked Servamp might be right up your alley.

The show focuses on Mahiru, a high school student who finds what he thinks is a stray cat. This "stray cat" actually turns out to be a powerful vampire who drags him into a dangerous supernatural conflict beyond anything he could have ever anticipated.

Despite its quality, Rainbow: Nisha Rokubō no Shichinin didn't get nearly the following it deserved. It's a gritty, disturbing series focusing on a group of boys and their struggle to survive the abuse they experience in a juvenile detention center. Despite the harrowing premise, the series is ultimately hopeful, focusing on the deep bonds between the boys and their determination to help each other. This beautiful show is an absolute must-see for any anime fan.

Jyu-Oh-Sei is listed (or ranked) 3 on the list 15 Great Anime We Guarantee You Haven't Seen

Jyu Oh Sei is a sci-fi anime that most people don't even know exists. 11-year-old twin brothers Thor and Rai Klein are sent to a distant planet after their parents are murdered. The planet, Chimaera, is dominated by man-eating plants, so survival isn't exactly easy. To get off the planet, they must conquer the few humans living there.

It's a cool sci-fi concept, but what makes the show really stand out is the characters. Every character has their own unique motivation and backstory, and their decisions make sense in light of who they are.

Heroman is listed (or ranked) 4 on the list 15 Great Anime We Guarantee You Haven't Seen

Like the wildly popular My Hero Academia, Heroman is an anime heavily influenced by American superhero comics. In fact, Heroman is actually written by comic book legend Stan Lee. Heroman is a fusion of American and Japanese influences, and the end result is excellent.

The setting, a fictional version of Los Angeles called Center City, is well-researched and beautifully drawn. The protagonist, Joey Jones, is smart and relatable, and the romance subplot is refreshingly organic. If you're fresh out of My Hero Academia episodes, Heroman is a great series to turn to next.
