Best controversial anime? If you think anime doesn't have an audience, you might be wrong. Crunchyroll, a platform that's a true paradise for anime fans, has a selection of anime with ratings that will surprise you. We've prepared a list of 10 options for you to binge-watch.
10. Tsugumomo

- Year: 2017
- Studio: Zero-G
- Episodes: 12
Opening the list of anime, we have "Tsugumomo," the kind of anime that mixes action with a fair amount of fanservice. The story follows Kazuya, a boy who has a headband (which looks more like a piece of ordinary cloth) that is actually a spiritual object, a tsukumogami, that transforms into the beautiful and spirited Kiriha. At first, you might think it's just another comedy anime with a good dose of ecchi, but you soon realize that the plot has more layers.
But the truth is, the show really stands out for the interactions between the characters and, of course, for the embarrassing (and funny) situations Kazuya gets himself into because of Kiriha. If you enjoy this type of anime with a good dose of action and comedy, but without losing that steamy atmosphere, Tsugumomo is a great choice. You can binge-watch it quickly and, before you know it, you'll be laughing at the characters' mishaps!
09. Manyu Scroll

- Year: 2011
- Studio: Hoods Entertainment
- Episodes: 12
“Manyu Scroll” is the most daring offering and certainly not for everyone. The story follows a warrior named Kagekiyo, who fights to protect a very peculiar secret: a magical scroll that grants her extraordinary abilities. However, the anime isn't just about fights and mysteries. It has a huge amount of fanservice, with many moments.
Although the main focus is on combat and the quest for power, the anime doesn't forget to make room for scenes of sexual tension and bolder elements. This creates a balance between epic fight moments and more "hot" situations. So, if you like an anime that mixes a bit of samurai history with a touch of provocation, "Manyu Scroll" might be your choice for a more irreverent marathon.
08. Shin Ikki Tousen

- Year: 2022
- Studio: Arms
- Episodes: 03
“Shin Ikki Tousen” is a continuation of the famous series “Ikki Tousen” and, like any good anime with that name, it's full of intense battles. The plot revolves around a group of students with combat skills who end up facing each other in epic duels. Each character has a connection to historical battle figures, which gives it a respectful touch of Japanese culture, but what really draws attention here are the moments of pure action and the scenes that explore the characters' more "intimate" side.
Furthermore, "Shin Ikki Tousen" isn't afraid to put fanservice in the foreground. If you're prepared for fierce fight scenes, this anime will please you. And if you've already watched "Ikki Tousen," you'll notice that the formula remains the same: action and that frenetic pace that keeps you hooked until the end.
07. The Garden of Sinners

- Year: 2007
- Studio: Ufotable
- Episodes: 01 (Movie)
Now, if you want something darker and with a much more adult vibe, "The Garden of Sinners" (or Kara no Kyōkai) is an anime that will leave you speechless. With a complex plot full of twists and turns, the series follows Shiki Ryougi, a girl with supernatural abilities who is shrouded in mystery. It's not an easy anime to digest, but that's exactly what makes it so fascinating. The visuals are impressive, with breathtaking animation, and the atmosphere is dark and mysterious, as if reality itself is constantly at stake.
What truly defines "The Garden of Sinners" is how it deals with violence, complex themes of identity, and even the supernatural, without fear of showing the darker side of life.
06. Recently, My Sister is Unusual

- Year: 2012
- Studio: Project No.9
- Episodes: 12
"Recently, My Sister is Unusual" is one of those anime you probably wouldn't tell your grandmother about, but it will make you laugh and feel awkward at the same time. The story follows a boy who ends up getting involved with his sister in a, shall we say, rather peculiar way. After the death of their parents, the protagonist's sister returns from an exchange program. The anime mixes comedy, ecchi, and a dose of romance, but the main attraction here is the unusual situations the characters get themselves into.
If you're looking for something light yet daring, "Recently, My Sister is Unusual" might be a good option. It plays with boundaries, but in a way that ends up being funny and even a little captivating.
5. Lupin the Third

- Year: 2012
- Studio: TMS Entertainment
- Episodes: 13
On the other hand, in the top 5 controversial anime, this one is a classic, and although it's best known for its mix of action and comedy, Lupin, the master thief, is that charismatic character who gets involved in incredibly ingenious heists. What sets Lupin apart from other more "adult" anime is its intelligent story full of twists and turns.
With great style, "Lupin the Third" blends action moments with a slightly more mature tone, especially when it delves into seduction and intrigue. If you've ever watched a spy movie, you'll definitely relate to the anime's atmosphere.
04. Prison School

- Year: 2015
- Studio: JCStaff
- Episodes: 12
"Prison School" is one of those anime that, once you start watching, you know you won't stop seeing at least 10 absurd scenes. The story follows a group of boys who are imprisoned in a school after getting into trouble. The plot revolves around these guys' attempts to escape from prison, but what really makes this anime stand out is its outrageous humor and the amount of fanservice.
This series is definitely for those looking for something uninhibited, full of double entendres, and that mixes action with... scenes. It's the kind of anime you watch with friends and laugh at the crazy situations and, of course, the strong female characters that will make you laugh.
03. The Sacred Blacksmith

- Year: 2009
- Studio: Manglobe
- Episodes: 12
Now, opening the top 3 with "The Sacred Blacksmith" is a blend of medieval fantasy and action that doesn't disappoint. The story follows Cecily, a young swordswoman seeking to improve her combat skills. She meets a blacksmith named Luke, who has a mysterious past and tremendous power.
The plot blends well-choreographed combat sequences with deeper themes. It's not as daring an anime as others on this list, but it has a good dose of moments that will appeal to those seeking a more mature narrative. If you enjoy a good medieval anime with action and interesting characters, "The Sacred Blacksmith" will be worth watching.
02. The Testament of Sister New Devil

- Year: 2015
- Studio: Production IMS
- Episodes: 12
The anime The Testament of Sister New Devil is the perfect choice for those who love a good fantasy anime with a good dose of action, comedy, and plenty of fanservice. The story follows Basara, a young man who finds himself having to protect his two sisters, who are actually demons.
In addition to action and magic scenes, "The Testament of Sister New Devil" throws a good amount of romance and fanservice into the mix, making each episode a real rollercoaster.
01. Tokyo Ghoul

- Year: 2014
- Studio: Pierrot
- Episodes: 12
Finally, this one couldn't be left out of the list. The story follows Ken Kaneki, a young man who becomes half-ghoul after a tragic accident and must learn to cope with his new identity in a world where humans and ghouls are constantly at war. The dark atmosphere and Kaneki's moral dilemmas make you question what is right and wrong, creating a complex and immersive plot.
But what truly puts "Tokyo Ghoul" at the top of the list is the fact that it's an anime with much more than just action. Tokyo Ghoul is the perfect choice for a marathon until the final season. It's definitely one of those anime that will leave you breathless and pondering human nature for a long time.
