20 Years Later, These Are the 10 Best Anime of 2006

Video games are a consistently fun way to tell stories, and they’ve come a long way since becoming popular in the 1960s. Each decade brings new ideas, and it’s interesting to see which types of games and series become the most popular over time.

While many anime fans fondly remember the classics from the 70s, 80s, and 90s, it’s important to recognize the impact of anime from the 2000s as well. That decade was a period of change, with some hits and misses, but 2006 specifically marked a turning point, producing several groundbreaking anime that are still popular today.

Death Note Is A Cruel Cat-And-Mouse Game To Apprehend A Supernaturally-Aided Serial Killer

I’ve noticed Death Note has really stuck with people – it’s become a classic psychological thriller, and even those who don’t usually watch anime seem to love it. What really grabbed me from the start was the story’s unique idea; it avoids the typical ‘power fantasy’ you often see, and that makes it instantly compelling.

Light Yagami discovers a mysterious notebook with the ability to kill anyone simply by writing their name in it. Initially, he’s excited by the prospect of eliminating criminals and making the world a better place, but he soon becomes increasingly reliant on the notebook’s power.

L is a highly skilled detective determined to uncover Light’s true identity and stop his crimes. Death Note explores the complex idea of being an accomplice, leaving viewers to question whether they’re rooting for Light to win or to be caught.

Code Geass Follows A Conflicted Anti-Hero Who Believes The Ends Justify The Means

Code Geass: Lelouch of the Rebellion is a surprising take on the giant robot and war story genres. It follows Lelouch Lamperouge, a prince in exile, who gains a special ability called Geass. This power lets him force anyone to obey his commands.

Lelouch starts a massive robot rebellion using a special power called Geass, aiming to take down the Holy Britannian Empire. What makes Code Geass stand out from other anime with robots is its smart political maneuvering and how it plays with people’s minds. But it’s really Lelouch himself – his inner struggles and his shift from a hopeful hero to a complicated, unpredictable character – that makes the story so compelling.

Lelouch’s actions, though destructive, are driven by a desire to create a better world. This complex moral ground is a key reason why Code Geass is so popular, and it’s a pattern we’ve seen in other hit anime like Attack on Titan.

Higurashi: When They Cry Unleashes Cosmic Horror & A Maddening Murder Mystery

Originally released as a visual novel, Higurashi: When They Cry has since expanded into various formats, including animated specials, sequels, and updated versions.

The world of Higurashi: When They Cry is incredibly complex, filled with time loops, witches, and a deadly curse. But the original anime from 2006 is a strong and unsettling starting point that works perfectly well even if you don’t explore the rest of the series.

This anime presents a chilling mystery: a secluded Japanese village trapped in a repeating time loop where someone always ends up murdered, and no one can break free. Originally released in 2006, its bleak and pessimistic tone captivated viewers and continues to set it apart even today, in 2026.

Aria The Natural Delivers Sublime Slice-Of-Life Storytelling In An Aquatic Paradise

Aria the Natural is the second installment in the Aria the Animation series, originally based on the Aqua manga. The story takes place in the 24th century on Mars, which has been transformed into a planet called Aqua. It follows Akari Mizunashi as she begins training to be a gondolier in the peaceful city of Neo Venezia.

The first series, Aria the Animation, introduces the world, while the second, Aria the Natural, focuses on heartwarming stories and character growth. Because the initial world-building is already done, Aria the Natural’s longer 26-episode season allows for a more relaxed and in-depth exploration of the characters and their lives – a fact reflected in the anime’s title.

Rather than focusing on a complex, ongoing story, Aria the Natural beautifully portrays Akari’s joyful experiences and the bonds she forms with her gondola-riding companions, Aika and Alice.

The Melancholy Of Haruhi Suzimiya Uses Slice-Of-Life Hijinks To Appease A Chaotic God

The anime The Melancholy of Haruhi Suzumiya can be complex, but it’s incredibly unique. It follows Kyon, a typical high school student, who gets caught up in the world of his eccentric classmate, Haruhi Suzumiya, who unknowingly possesses the power to change reality itself.

Kyon and his friends, known as the SOS Brigade, have a big responsibility: keeping Haruhi’s incredible powers from accidentally destroying the world. The show, The Melancholy of Haruhi Suzumiya, expertly mixes intense, world-altering stakes with everyday high school life, creating a unique and fun blend of sci-fi craziness and relatable school scenarios.

The original 2006 broadcast of The Melancholy of Haruhi Suzumiya had 14 episodes. A later version, which aired in 2009, rearranged the episodes and included the famously divisive ‘Endless Eight’ arc. So, the 2006 version doesn’t include that experimental addition.

Ergo Proxy Uses An Android & Human War To Explore A Dark & Disturbing Future

The 2006 anime series Ergo Proxy is a 23-episode thriller set in a post-apocalyptic, cyberpunk world. It delves into the complex connection between humans and robots, a theme often seen in sci-fi anime. However, Ergo Proxy stands out by exploring these ideas through philosophical and Gnostic concepts, adding a unique layer to questions of control and what it means to be self-aware.

I watched this series, Ergo Proxy, and it really drew me in with its complicated story. It starts with a fragile peace between humans and androids, but then this dangerous new species, called Proxy, shows up and throws everything into chaos. Over 23 episodes, the show doesn’t shy away from big questions about what it means to exist, and it really explores feelings of hopelessness and the idea that life might be meaningless. It’s a deep dive into some very complex characters, too.

Despite being a dark anime, Ergo Proxy handles its mature themes thoughtfully, using them to explore meaningful concepts. What’s particularly impressive is how it combines 2D and 3D animation – a difficult feat for anime of the 2000s – to really bring its cyberpunk setting to life.

Ouran High School Host Club Satirizes & Improves Upon Reverse Harem Romances

Originally aired in 2006, Ouran High School Host Club is a 26-episode anime that remains a popular example of a classic romantic comedy, and is often discussed as a defining series of the genre.

The anime Ouran High School Host Club starts with a funny situation: a girl named Haruhi Fujioka ends up in debt and has to work at an exclusive boys’ club to pay it off. To do this, she pretends to be a boy! The show playfully makes fun of common anime clichés and over-the-top storylines.

Even though Ouran High School Host Club is known for its clever humor and satire, it also tells a genuinely sweet and engaging love story. Haruhi is a particularly memorable heroine, and it’s fun to watch how she impacts everyone around her – both in the Host Club and those who are interested in her.

Nana Is An Emotional Look Into The Chaotic Lives Of Twentysomethings

Nana is a deeply touching and beautifully crafted story. It realistically portrays the complicated lives of two young women, both called Nana, who find themselves living together.

Nana Osaki is a strong-willed aspiring punk rock singer, and Nana Komatsu is a sweet, hopeful romantic. The series Nana offers a realistic and honest portrayal of young adulthood, showing both the joys and struggles of love, heartbreak, and difficult choices, without glossing over tough issues like addiction.

It’s tough to see these characters make bad decisions, but their struggles will likely resonate with anyone who’s been through a similar time in their life.

Welcome To The N.H.K. Is An Earnest Examination Of Frayed Mental Health & Debilitating Anxiety

Welcome to the N.H.K. is a thought-provoking anime about a 22-year-old who has withdrawn from society and become a ‘hikikomori’ – someone who avoids social contact. Tatsuhiro Sato thinks his problems are caused by a secret plot carried out by a mysterious group called the N.H.K.

Tatsuhiro is trying to overcome his unhealthy habits and find a way to move forward, but he has trouble controlling his feelings and thoughts. While there’s a darkly humorous side to his anxieties, the show Welcome to the N.H.K. avoids making fun of or romanticizing the experience of being a hikikomori – someone who withdraws from society.

Welcome to the N.H.K. is a powerful and insightful story that honestly shows what life can be like for people battling social anxiety. Viewers will find themselves rooting for Tatsuhiro, a relatable and sympathetic character, as he tries to overcome his challenges.

Black Lagoon Celebrates A Robust Criminal Underworld Through An Overwhelmed Outsider’s Perspective

Black Lagoon offers a fresh perspective on crime stories, following Rock, a Japanese businessman who is unexpectedly thrust into the world of piracy and mercenary work after being kidnapped. He quickly leaves behind his old, corporate life and becomes a skilled smuggler.

I love how Black Lagoon throws you right into this crazy world of crime through the eyes of Rock, a guy totally out of his element! It’s a really engaging way to start the series. The show is set in a reimagined 90s, and it feels like a total playground for criminals – you’ve got everything from Chinese Triads to the Russian mafia, all vying for power. It’s such a wild and diverse criminal underworld!

Black Lagoon explores the blurry lines between right and wrong for criminals, delving into their complex motivations. But it’s also a high-energy anime packed with explosive action and wild gun battles.
