Credits:- Triangle Studio, Gainax, Sunrise Inc.

Do you think the most popular anime are adaptations of long-running manga? Then you’re in for a surprise. Yes, for decades, the standard pipeline has involved a successful manga or light novel being transitioned onto the screen. However, there is a special category of storytelling that defies this trend: original anime. These are works written specifically for the screen, allowing directors and studios to craft narratives without the constraints of pre-existing source material. 

Since they aren’t bound by the pacing of a book, original anime often deliver some of the most impactful and definitive endings in the medium. For any viewer, watching original anime is essential to understanding the true artistic potential of the flamboyant anime industry. 

So, we took the liberty of ranking ten such original masterpieces that prove you don’t need a manga to create a cultural phenomenon. These original works offer a purity of vision that is rare to find elsewhere. Let’s dive in!

10 Sonny Boy Is a Surreal Journey Through the Pains of Growing Up

Sonny Boy is a 2021 science fiction series produced by Madhouse and directed by Shingo Natsume. The story begins when a high school suddenly drifts into a void, leaving the students stranded in alternate dimensions with strange supernatural powers. Unlike traditional “isekai” adventures, Sonny Boy is an abstract, philosophical exploration of adolescence and institutional rot.

The best thing about this anime is its refusal to use standard tropes, opting instead for surrealist imagery to capture the confusion of youth. It ranks tenth because while its non-linear logic is brilliant and unique, it requires a high level of patience and interpretation from the viewer. Anime lovers should watch it for its unique art style and haunting soundtrack.

9 Psycho-Pass Challenges Everything You Know About Sci-Fi Justice

Produced by Production I.G., Psycho-Pass is a cyberpunk thriller set in a future where the “Sibyl System” measures a person’s criminal intent before they even commit a crime. The story follows rookie Inspector Akane Tsunemori as she discovers the dark reality behind this “perfect” society. 

The standout feature of this series is its deep intellectual inquiry into the morality of law and order. It is a must-watch for fans of psychological suspense because it never gives easy answers to complex ethical questions. And in case you are a fan of Blade Runner or Ghost in the Shell, then this anime is for you. It ranks ninth as a definitive pillar of modern, mature adult sci-fi storytelling.

8 Death Parade Forces Fans to Question the Nature of the Human Soul

Death Parade originated from a short film titled Death Billiards, produced by Madhouse. The series takes place in a mysterious bar where the recently deceased must compete in high-stakes games to determine the fate of their souls. The best thing about this anime is its intense emotional weight; it uses simple parlor games to strip away a character’s mask and reveal their true nature.

Viewers should watch it for its haunting atmosphere and the way it handles themes of grief and judgment. The show masterfully tackles the complexities of human nature and the ambiguity of morality. It is ranked eighth because it provides a complete, emotionally devastating narrative in just twelve episodes, showcasing the efficiency of original storytelling.

7 Kill la Kill Redefines Action Through Its Fearless Satirical Lens

Kill la Kill was the debut television series from Studio Trigger, directed by Hiroyuki Imaishi. The story follows Ryuko Matoi, a girl searching for her father’s killer, who ends up at Honnouji Academy, where clothes grant superpowers. The standout aspect of this anime is its over-the-top, frenetic energy and its satirical take on magical girl tropes and fascism.

People should watch it for the breathtaking action sequences and the surprisingly deep themes of self-acceptance and body autonomy. It ranks seventh on this list because it perfectly encapsulates Studio Trigger’s bold, loud, and unapologetically original vision. Hence, proving that a show doesn’t need a manga to become a cultural phenomenon.

6 Cowboy Bebop Remains the Definitive Icon of the 90s Era

Directed by Shinichiro Watanabe at Sunrise, Cowboy Bebop is a genre-defying space western that follows a ragtag group of bounty hunters. The series is world-famous for its “cool” factor, perfectly blending a jazz-inspired soundtrack with noir-style storytelling. The best thing about Bebop is its episodic variety, moving from high-speed action to deep, existential loneliness. 

This further allows for diverse stories ranging from slapstick comedy to tragic drama. It is a mandatory watch because it defined the global perception of anime for an entire generation. It sits at number six because it remains the benchmark for how to build a rich, immersive world without a single page of source material.

5 Samurai Champloo Is a Brilliant Mix of History and Hip Hop Culture

Another masterpiece by Shinichiro Watanabe, Samurai Champloo reimagines Edo-period Japan through the lens of hip-hop culture. Following the journey of Mugen, Jin, and Fuu, the anime is a stylistic marvel that replaces traditional samurai tropes with breakdancing, graffiti, and lo-fi beats.

The best thing about the show is the chemistry between the three leads and its incredibly fluid fight choreography. Viewers should watch it for its unique vibe and rebellious spirit. It is ranked fifth because it proved that original anime could be both culturally significant and immensely entertaining. Plus, Netflix confirmed a live-action adaptation of the anime.

4 Paranoia Agent Keeps You At the Edge of Your Seat

Paranoia Agent is the only television series created by the late, legendary director Satoshi Kon. The story starts with a series of attacks by a boy on rollerblades known as “Lil’ Slugger” and quickly spirals into a surreal social commentary on modern Japan. The standout feature is Kon’s ability to blur the lines between reality and delusion, creating a sense of creeping dread.

This is Satoshi Kon’s least-known work, which has extremely disturbing themes in it. You should watch it for its psychological depth and masterful editing. It ranks fourth because it is one of the most sophisticated thrillers ever made, using the medium of animation to explore the collective psyche of a nation.

3 Code Geass Stands Out as a Masterclass in Mecha and Political Drama

Code Geass: Lelouch of the Rebellion (2006) is a high-stakes drama produced by Sunrise featuring designs by CLAMP. It follows Lelouch, an exiled prince who uses the power of “Geass” to lead a revolution against the Holy Britannian Empire. The best thing about this anime is the tactical genius of its protagonist and its unrelenting pace.

Anime lovers should watch it for the constant plot twists and one of the most iconic, tragic endings in fiction. It ranks third because it is the ultimate example of a blockbuster original anime that perfectly balances political intrigue, mecha action, and deep emotional stakes.

2 Serial Experiments Lain Predicted Our Digital Future Decades Ago

Released in 1998, Serial Experiments Lain is an avant-garde cyberpunk series that explores the “Wired,” a precursor to the modern internet. It follows a shy young girl who becomes obsessed with the digital world, eventually questioning the boundary between physical and virtual existence. Serial Experiments Lain accurately predicted how the world would turn to social media, leading to identity fragmentation and a fractured global connectivity.

This anime is a must-watch for anyone interested in the philosophy of technology. If you liked Netflix’s Pluto, then you should watch this anime. It takes the second spot because it is a haunting, visionary work that feels even more relevant today than it did 28 years ago.

1 Neon Genesis Evangelion Is Still the Greatest Animated Series of All Time

Neon Genesis Evangelion (1995), directed by Hideaki Anno and produced by Gainax, is the pinnacle of original anime. While it begins as a mecha show about teenagers fighting “Angels,” it evolves into a deep, psychological deconstruction of the human condition and depression. The best thing about Evangelion is its complexity. It completely changed the industry and how stories are told in animation.

Viewers should watch it because it is a cultural landmark that remains a subject of intense study and debate. And yes, there’s a proper watch order to enjoy this masterpiece. It is ranked at No. 1 because where else do you rank an anime so profound that it left a lasting impact on the medium and its fans? It is the ultimate original animated series.

Original anime serve as the lifeblood of the industry’s innovation. While adaptations bring beloved stories to life, original series like Serial Experiments Lain and Cowboy Bebop are the ones that truly push the medium forward into uncharted territory.
