20 Best Seinen Manga, Ranked

For most, the world of anime and manga is dominated by shonen series, typically action-focused storyies aimed primarily at a young male demographic (famed hits like Dragon Ball Z and even Death Note included). However, there are also anime and manga aimed at an older demographic, and that category is known as seinen.

So, what is seinen? “Seinen” is media aimed at older males in their late teens and 20s. In general, these series tend to star older protagonists, feature more explicit content, and deal with darker subject matter (though not all have to). While that male audience is the only real requirement to be seinen, the series can be enjoyed by anyone, and contains the variety to do exactly that. Below are ten of the absolute best seinen series available, offering great entry points into this diverse and underappreciated genre.

20 Miss Kobayashi’s Dragon Maid

Created By Coolkyousinnjya; Serialized In Manga Action

Coolkyousinnjya’s Miss Kobayashi’s Dragon Maid stars Kobayashi, an overworked office worker who gets drunk one night and saves the life of a dragon who had been stabbed with a sword. The dragon, Tohru, is so thankful that she takes on a human form and becomes Kobayashi’s live-in maid, and their developing relationship leads to Kobayashi constantly learning more about Tohru’s world and the complexities of the people who inhabit it.

Not only does the series have surprisingly good fight scenes and worldbuilding, but Miss Kobayashi’s Dragon Maid‘s character writing always stands out for its stellar development and thoughtful execution, especially when it comes to Kobayashi and Tohru’s relationship. It’s a far more heartwarming story than it appears, and it’s plenty worth reading as a result, even if it does tend to be a little too raunchy.

19 Land Of The Lustrous

Created By Haruko Ichikawa; Serialized In Monthly Afternoon

Haruko Ichikawa’s Land of the Lustrous is a visually beautiful and creative fantasy seinen manga. As eye-catching as Ichikawa’s emotionally expressive art style is, the series doesn’t slack on depth in the story department, either. The story follows Phos, a member of a humanoid jewel-like species of beings who are deemed weak by their peers in their war against the Lunaris, who want to hunt them down for their value as jewels.

As the story goes on, Phos discovers that their powers come with a brutally steep cost. These revelations gradually unwind in a shocking fashion, and Land of the Lustrous‘ CG anime adaptation garnered special praise for accomplishing the rare feat of creating exceptional 3D animation that does justice to one of the best seinen manga out there.

18 20th Century Boys

Created By Naoki Urasawa; Serialized In Big Comic Spirits

Though he’s more well-known for his work on Monster, Naoki Urasawa’s 20th Century Boys is another excellent seinen effort by the writer/artist. Urasawa has made himself known for stringing together mysteries that are equal parts intricate and engrossing at the core of his stories, and 20th Century Boys works that in with a sci-fi twist.

The plot follows an average convenience store manager, named Kenji Endo, who starts to feel suspicious of the suicide of a childhood friend and a dangerous new cult on the rise. From there, 20th Century Boys spirals into a tense psychological and conspiracy thriller that easily ranks among the best seinen series.

17 Kingdom is One of the Best Historical Fiction Manga

Created By Yasuhisa Hara; Serialized In Weekly Young Jump

With a somewhat similar genre appeal to Vinland Saga, writer Yasuhisa Hara’s Kingdom is an equally acclaimed historical fiction and sweeping seinen drama. Kingdom‘s length and success make it rival One Piece, but in a very different setting. Its story is a fictionalized version of the Warring States period of China, during the fifth century BCE.

Kingdom uses this setting to follow a war orphan named Xin, who is on a grand quest to become the world’s greatest general, and plans to unify China in the process. The seinen manga series has been ongoing since 2006, and it’s been acclaimed for maintaining a thrilling narrative throughout thanks to its compelling characters and strikingly expressive artwork across 64 volumes and counting.

16 Bocchi The Rock!

Created By Aki Hamazi; Serialized In Manga Time Kirara Max

Aki Hamazi’s Bocchi the Rock! stars Hitori Gotoh, a girl with crippling social anxiety who learned the guitar in a failed attempt at making friends until the day she ran into a girl begging her to be the guitarist for her band, Kessoku Band. Now finally having a proper outlet for her music, Hitori, now nicknamed “Bocchi”, will use her time in Kessoku Band to both make friends and slowly learn to overcome her social anxiety.

Just like the hit anime of the same name, Bocchi the Rock! excels through its thoughtful and often surreal exploration into social anxiety, and the comedic character writing and pleasing artwork to accompany it always works to sell that even further. Anyone who was a fan of the anime will find plenty to love about the manga, as well, especially when it’s currently the only way to keep progressing through the story.

15 The 100 Girlfriends Who Really, Really, Really, Really, Really Love You

Created By Rikito Nakamura & Yukiko Nozawa; Serialized In Weekly Young Jump

Rikito Nakamura and Yukiko Nozawa’s The 100 Girlfriends Who Really, Really, Really, Really, Really Love You stars Rentaro Aijou, a young boy who’s failed to find love after going through 100 confessions over the past 15 years. After his latest failure, the God of Love tells Rentaro that he will meet and fall in love with 100 soulmates in high school, but he needs to love them all equally, or else they could literally die of a broken heart.

As controversial as harem anime and manga tend to get, The 100 Girlfriends Who Really, Really, Really, Really, Really Love You works for how well it commits to its premise and effortlessly justifies Rentaro having a harem beyond fanservice, all of which is perfectly complemented by its absurdist, parody-style writing. The series excels in both romance and comedy, and it’s one every seinen fan should try and read.

14 Delicious In Dungeon

Created By Ryoko Kui; Serialized In Harta

Ryoko Kui’s Delicious in Dungeon opens with Laios’ adventure party being wiped out by a dragon and Laios’ sister, Falin, being eaten alive. What’s left of Laios’ party must hurry back through the dungeon to revive Falin, but they lack the funds a party would normally need to do so. Laios’ solution, much to everyone’s chagrin, is for them to eat the monsters they encounter in the dungeon, although for Laios, it’s less a survival tactic and more a dream of his he finally gets to fulfill.

While mostly a comedic take on JRPGs, what truly sells Delicious in Dungeon is its stellar artwork and writing combined with its creative and intricate worldbuilding that only gets better as the story progresses. Because of that, Delicious in Dungeon is one of the best takes on classic fantasy in recent years, and anyone looking for something like that won’t be disappointed.

13 Record Of Ragnarok

Created By Shinya Umemura, Takumi Fukui, & Azychika; Serialized In Monthly Comic Zenon

In Shinya Umemura, Takumi Fukui, and Azychika’s Record of Ragnarok, all the gods in the universe have decided that humanity has become irredeemable and needs to be erased, but the valkyrie Brunhilde offers an alternative. Rather than just erase humanity outright, the 12 strongest gods will fight history’s 12 strongest humans in a tournament called Ragnarok, giving humanity a chance to fight for their right to exist and the gods a chance to definitively prove their superiority.

Record of Ragnarok is a story that’s very much all about fighting and little else, but fortunately, Record of Ragnarok‘s gorgeous artwork and fight choreography always results in incredible action in every fight, and the few bits of depth the characters are afforded are plenty great to see, as well. There are few manga as good at pulling off pure action as well as Record of Ragnarok, and that’s unlikely to ever change.

12 Grand Blue Dreaming

Created By Kenji Inoue & Kimitake Yoshioka; Serialized In Good! Afternoon

Fantasy and high-octane action will always attract plenty of attention, but Kenji Inoue and Kimitake Yoshioka’s Grand Blue is a welcome change of pace. Grand Blue is a grounded seinen slice-of-life/coming-of-age comedy revolving around college student Iori Kitahara. He’s looking forward to starting this new phase in his life, staying in a room above his uncle’s diving shop.

Iori tries to steer clear of the antics of the diving club there, who are more interested in partying than actually diving, but eventually gets roped into the group’s exploits and learns more about diving through his cousins. It’s become a fan favorite when it comes to seinen manga in the slice-of-life genre, with an anime adaptation by studio Zero-G earning a strong reception as well.

11 Rosen Garten Saga

Written By Fujisakimori; Illustrated By Bakotsu Tonooka; Serialized On Comiplex

Fujisakimori and Bakotsu Tonooka’s Rosen Garten Saga takes place in a world where all myths are true, although they often have far more sexual bends to them than their real-life counterparts. When the village of the inexplicably ostracized Lynn is attacked by vandals, Lynn is saved after being possessed by the legendary warrior Siegfried, and while she hates the perverted situations he forces her into, she’ll go along with it to try and win the heart of the beautiful warrior Brunhilde.

While Rosen Garten Saga often makes sex, rape, and fetishes integral to its story, not only does it end up looping back around to pure absurdity, but it’s paired surprisingly well with Rosen Garten Saga having some of the best artwork and most creative fight choreography of any modern manga. Rosen Garten Saga is one of the best seinen manga around and is great for fans of pure action.

10 Parasyte

Created By Hitoshi Iwaaki; Serialized In Monthly Afternoon

In Hitoshi Iwaaki’s Parasyte, alien parasites came to Earth one night, each one taking over someone’s body and turning them into bloodthirsty monsters who feed on humanity. By pure chance, Shinichi Izumi gets away with a parasite only possessing his right hand, the parasite then adopting the name Migi, and together, they’ll protect Shinichi’s home from the evil parasites, all while Shinichi repeatedly has to grapple with the slow decline of his humanity.

Not only does Hitoshi Iwaaki’s artwork always do a great job of selling gore and body horror, but the dramatic character writing of Parasyte never fails to sell the philosophical elements the manga always delves into, especially when it comes to Shinichi struggling with his humanity. Parasyte can easily be seen as one of the most influential horror manga of all time, and overall, it’s easy to see why.

9 Dead Dead Demon’s Dededede Destruction

Created By Inio Asano; Serialized In Big Comic Spirits

Inio Asano’s Dead Dead Demon’s Dededede Destruction starts three years after an alien spaceship appeared above Tokyo. The aliens have done nothing in that time, but they’ve still sparked conflict and discussion around the world as people can’t agree on what to do about them. For the most part, though, Dead Dead Demon’s Dededede Destruction is unconcerned with all of that and focuses primarily on the daily lives of Kadode, Oran, and their circle of family and friends.

Between its unique character writing and cutting social commentary, a plot that never fails at building tension with every volume, and some of the most gorgeous artwork in any manga, there are no stories with as unique a take on slice-of-life storytelling as Dead Dead Demon’s Dededede Destruction. It’s not Inio Asano’s most famous work, but any fan of his would be remiss to pass up such a clear modern classic.

It’s not Inio Asano’s most famous work, but any fan of his would be remiss to pass up such a clear modern classic.

8 Hellsing

Created By Kouta Hirano; Serialized In Young King OURs

Kouta Hirano’s Hellsing takes place a century after Bram Stoker’s Dracula and is centered around the Hellsing Organization, an organization of vampire hunters headed by Van Helsing’s descendant, Sir Integra Fairbrook Wingates Hellsing. Integra is the only person in the world who can command Alucard, the world’s deadliest and most infamous vampire, and together, the two protect the world from other vampires looking to cause trouble, most notably those associated with the Nazi organization Millennium.

Thanks to Kouta Hirano’s unique character writing and an art style that perfectly works for gore, Hellsing is a manga that never fails at selling itself as a stunning piece of gothic horror, especially when it comes to the ever-escalating final arc of the story. The OVA series Hellsing Ultimate is the most iconic part of the franchise, but that doesn’t make the manga any less worth reading for fans old and new.

7 Goodnight Punpun

Created By Inio Asano; Serialized In Big Comic Spirits

Inio Asano’s Goodnight Punpun follows the life of an 11-year-old boy named Punpun Onodera as he navigates the complications of childhood, adolescence, and adulthood. This is another grounded slice-of-life seinen manga, but it’s one that takes a darker and more dramatic approach. Punpun is initially a naive romantic with preconceived notions of what romance is like, and he ends up discovering the complications of not only keeping a relationship together, but the bleaker aspects of those he once looked up to.

Punpun realizes this after witnessing his father assault his mother, sending him into a spiraling state of fearful reclusiveness. Goodnight Punpun has been praised for being a compelling, coming-of-age drama that explores dark psychological themes and social commentary, ensuring its place among the best seinen manga.

6 Monster

Created By Naoki Urasawa; Serialized In Big Comic Original

Naoki Urasawa’s Monster is one of the few acclaimed seinen manga that could justify a live-action adaptation, should the likes of HBO take interest in it. It’s one of the best and most grounded seinen manga series out there, telling a grim and riveting crime drama story that could arguably serve as a premise for a series like True Detective.

Monster tells the story of Kenzo Tenma, a Japanese doctor working and living in Germany. His life first begins to crumble when he refuses to operate on a political official in favor of a child in critical condition. Years later, things begin to unravel further, as that same boy returns as an elusive, psychopathic serial killer. A gripping crime-thriller, Monster‘s anime adaptation still stands as one of the greatest seinen anime ever produced.

5 Pluto

Created By Naoki Urasawa; Serialized In Big Comic Original

Naoki Urasawa’s Pluto is a modern reimagining of the classic “Greatest Robot on Earth” story arc from the legendary manga Astro Boy by Osamu Tezuka. In this take on the series, robot detective Gesicht begins investigating the murders of the world’s strongest robots by a mysterious figure named Pluto, and in doing so, he uncovers a massive conspiracy that threatens to put the entire world at risk.

Naoki Urasawa is one of the most famous mangaka in the business, and Pluto might easily be his best work. Between his always incredible artwork, the stellar action, and the war-based social commentary that’s still relevant after over 20 years, Pluto is as perfect a modernization of Osamu Tezuka’s Astro Boy as someone could have hoped for, and even those who haven’t experienced the original story will surely find a lot to love.

4 Vinland Saga

Created By Makoto Yukimura; Serialized In Monthly Afternoon

Despite 2019 being a stacked year for anime with the likes of Demon Slayer, Attack on Titan season 3, and more, Vinland Saga still managed to be one of the best series of the year. Makoto Yukimura’s original manga is a sweeping Viking epic, with its story evolving into a philosophically and emotionally resonating journey of self-discovery for Thorfinn that explores themes of redemption, the aftermath of war, and growing past vengeance.

This seinen manga series is a consistently enthralling tale of historical fiction, able to tell immersive, character-driven stories without a fantasy wrapping. The strong reception to Vinland Saga‘s first anime season made sure that a second one debuted in 2023, and it gained a spot among the best anime of the recent past.

3 Vagabond

Created By Takehiko Inoue; Serialized In Morning

Vagabond is one of those manga series that arguably can’t be adapted in a way that’s worthy of writer/artist Takehiko Inoue’s work. In addition to telling a deeply intimate and character-driven story, Inoue could be put on the same pedestal as the late, great Kentaro Miura of Berserk when it comes to his artwork.

Vagabond chronicles a fictionalized account of Musashi Miyamoto on his journey to become the “strongest under the Sun.” He gains a daunting reputation as such, but he begins to discover that such a title isn’t the key to feeling whole. Unfortunately, Vagabond remains unfinished, but Inoue’s storyboards for the ending have been released online, which should provide some closure to one of the best seinen manga ever written.

2 JoJo’s Bizarre Adventure: Steel Ball Run

Created By Hirohiko Araki; Serialized In Ultra Jump

When it comes to popularity, Hirohiko Araki’s colorfully chaotic and stylish JoJo’s Bizarre Adventure has to take first place. It’s one of the most vibrant and inventive manga ever, with the series getting even more mainstream with the ingenious and iconic invention of Stands. As esteemed as the sprawling generational adventures of the Joestar bloodline have been, however, Steel Ball Run still sits at the top for many veteran fans. This seventh part of the long-running manga rebooted the series, aiming at older fans in the seinen demographic for the first time.

Though
Steel Ball Run
has yet to be officially translated by Viz, Parts 1 – 5 are fully translated with a translation of Stone Ocean currently ongoing.

Steel Ball Run takes things back to the American Old West, where Gyro Zeppeli and Johnny Joestar take part in the titular grand race for a shot at winning $50 million. The JoJo’s Bizarre Adventure anime has excellent adaptations of the story’s arcs, but longtime fans are surely salivating at the thought of a Steel Ball Run anime.

1 Berserk

Created By Kentaro Miura; Currently Written By Kouji Mori; Serialized In Young Animal

While it may sound cliché, there’s some merit in hearing Berserk touted as the seinen manga equivalent of George R. R. Martin’s A Song of Ice and Fire novels. Series creator Kentaro Miura passed away in 2021, unfortunately, but the series has been picked up by his longtime friend and fellow mangaka Kouji Mori. Miura will be sorely missed, but the late, great writer/artist leaves behind a revered legacy as having put one of the greatest dark fantasy manga ever put to pen and paper. It’s filled with stunningly detailed art, cathartic fights, and dense fantasy worldbuilding.

It must also be said that the grueling and horrific scenes in the series are understandably not for everyone, but several of Berserk‘s powerful themes of healing from trauma, letting go of the past, and the power of sheer human will at its best are timeless. Guts, Casca, and co.’s personal journeys have been punishing ones, but the story of Berserk evolves past revenge and into one of inspiring perseverance and indomitable hope. With its impressive legacy that continues to this day, Berserk remains the greatest seinen manga of all time.
