Best Seinen Manga With No Anime Adaptations

As someone who has been an avid fan of manga for years, I can’t help but be intrigued by the world of Seinen manga – a genre that caters to older audiences with more mature themes and complex character development. Amongst this rich tapestry of stories, there are some gems that have left an indelible mark on me, and one such title is “REAL” by Takehiko Inoue.


As a fan of both shōnen and seinen manga, I have to admit that the excitement and action-packed plots of shows like Dragon Ball and My Hero Academia can be thrilling. But after a while, it becomes predictable – every problem seems to be solved with a powerful punch or a new ability. That’s where seinen manga comes in! Targeted at teenagers and adults, these stories tackle more mature themes and present complex issues that can’t always be resolved through brute force or friendship alone.

Some seinen mangas, which span various genres such as fantasy (“Berserk”), sci-fi (“Ghost in the Shell”), and mystery thrillers (“Erased”), don’t get transformed into anime despite their popularity. Not every shonen manga results in an anime, and similarly, not all seinen series receive this treatment. Despite the reasons behind these unanimated productions, here are some well-known mangas that currently remain in print form.

As a long-time manga enthusiast and avid user of MyAnimeList (MAL), I’ve come across numerous gems in the world of seinen manga that don’t have anime adaptations yet. I’ve recently updated my personal list, and I’m thrilled to share some of these hidden treasures with you all.

24 Maka-Maka

MyAnimeList Score: 7.19

Best Seinen Manga With No Anime Adaptations

  • Written and illustrated by Torajirō Kishi.
  • 2 Volumes, 24 Chapters.
  • Originally published in English by Media Blasters.

Seinen manga may appear soft and tender at times, but they can also tackle mature themes in various ways. In contrast, “Maka-Maka” by Torajirō Kishi for “Pent-Japan Special” is an adult story that doesn’t hold back on explicit content. It follows the journey of two women who form a deep connection despite their differences.

Nene holds a passion for fashion and enjoys socializing, but she harbors insecurities and clings tightly. Contrarily, Jun is an arrogant artist with a penchant for disregarding university classes and smoking, often acting delinquent. Despite their contrasting traits, they find common ground in their shared interests and trust issues. Nene is drawn to Jun’s boldness and independence, while he admires Nene’s creative approach. Their romance unfolds with an enthralling narrative that matches the intrigue of the vividly portrayed scenes.

23 Chōjin X

MyAnimeList Score: 7.41

Best Seinen Manga With No Anime Adaptations
  • Written and illustrated by Sui Ishida.
  • 10+ Volumes, 52+ Chapters.
  • Available in English via Viz Signature.

Sui Ishida, the mind behind Tokyo Ghoul, launched his new original manga, Chōjin X, on Tonari no Young Jump website in May 2021. The serialization has had an uneven publication pace since then, with a brief stint in Weekly Young Jump towards the end of 2021 and early 2022. Given this pattern, it’s likely that the absence of an anime adaptation for Chōjin X is due to insufficient content being available at present. To date, only five tankobon volumes have been released, with three in English translation, and additional chapters are still being compiled.

In simpler terms, Azuma and Tokio are ordinary humans trying to survive in Japan after the devastation caused by super-powered individuals called Chōjin. They’re forced to find a way to make a living when confronted by one such Chōjin. Desperate for an solution, they attempt to use a drug to gain superpowers. The drug takes effect on Tokio but not Azuma, leaving Tokio with new abilities that he must learn to control while concealing them from his loved ones and friends, lest they be endangered by his newfound powers.

22 The Old Frontier Knight Bard Loen

MyAnimeList Score: 7.57

Best Seinen Manga With No Anime Adaptations
  • Written by Shienbis.
  • Illustrated by Morio Kikuishi.
  • 10+ Volumes, 70+ Chapters
  • Available in English via Kodansha USA & K Manga.

In the world of Berserk, Guts’ adventure continues, contrasting with Bard Loen’s near-completed journey. Renowned as the “People’s Knight,” Bard Loen has spent decades assisting others and serving the illustrious Tersia Family. Eager to bestow riches and recognition upon him, the family proposes retirement and a life of leisure. However, with no familial ties beyond his students, Bard chooses instead to embark on one final voyage in search of a tranquil sanctuary where he can peacefully end his days.

The situation for Tersias and his daughter Aidra, who were raised by Bard since birth, becomes more complex as new obstacles emerge. Thus, Bard’s final journey marks the start of a fresh adventure. For those tired of extravagant isekai stories, Bard Loen offers a respite. While it incorporates a modest amount of magic, it primarily focuses on mature themes, heartfelt moments, and authentic sword fights. The world-building is intriguing as well.

21 I Am A Hero

MyAnimeList Score: 7.66

Best Seinen Manga With No Anime Adaptations
  • Written and illustrated by Kengo Hanazawa.
  • 22 Volumes, 264 Chapters.
  • Available in English via Dark Horse Comics.

Drama is all well and good, but how about a horror story? Kengo Hanazawa’s I Am a Hero is about Hideo Suzuki, a 35-year-old manga assistant suffering from low self-esteem and hallucinations. He feels stuck in a rut with no place in the world, just as the world ends. Japan is struck by a viral outbreak that turns people into homicidal cannibals. With only a shotgun in his hands, Hideo tries to escape Tokyo and the zombie-like hordes.

Along his journey, he encounters uninfected individuals and gains valuable survival skills through painful experiences. This story shares similarities with “The Walking Dead,” but the virus brings about consequences beyond turning people into zombies. The manga was serialized from 2009 to 2017 in “Big Comic Spirits.” Three spin-offs were developed, located in Osaka, Ibaraki, and Nagasaki, but none of them were turned into anime. However, the primary series was adapted into a live-action film in 2016.

20 All You Need is Kill

MyAnimeList Score: 7.76

Best Seinen Manga With No Anime Adaptations
  • Light Novel Written by Hiroshi Sakurazaka and Illustrated by Yoshitoshi Abe.
  • Adapted into a manga by Ryōsuke Takeuchi and Takeshi Obata.
  • 2 Volumes, 17 Chapters.
  • Available in English via Viz Media.

Hiroshi Sakurazaka and Yoshitoshi Abe’s light novel “All You Need is Kill” has been transformed into various forms of media with the exception of animation. This novel was first released in Super Dash Bunko back in 2004. Since then, it has been developed into manga by Ryōsuke Takeuchi of “Moriarty the Patriot” fame and Takeshi Obata, the creator of “Death Note.” Additionally, an English graphic novel version was produced by Nick Mamatas and Lee Ferguson. A major Hollywood film titled “Edge of Tomorrow,” starring Tom Cruise, was also based on this work.

In the narrative of Sakurazaka, new soldier Keiji Kiriya meets his demise during a clash with extraterrestrial adversaries named Mimics. But instead of meeting his end permanently, he finds himself back at the beginning of that fateful day. Caught in a repeating cycle reminiscent of the movie “Groundhog Day,” Keiji must unravel the mystery and discover a means to escape this recurring first day on the battlefield.

19 Blood On The Tracks

MyAnimeList Score: 7.98

Best Seinen Manga With No Anime Adaptations
  • Written and illustrated by Shūzō Oshimi.
  • 17 Volumes, 153 Chapters.
  • Available in English via Vertical Comics.

For some viewers, “Blood on the Tracks” may ring a bell from SuperEyepatchWolf’s YouTube analysis titled “The Manga That Leaves an Emotional Scar.” Alternatively, others might identify it as the work of its creator, Shūzō Oshimi, known for his dark manga series “Flowers of Evil.” Regardless of the recognition source, be prepared for a more haunting read than the title suggests. Seiichi Osabe’s seemingly ordinary life takes an unexpected turn during a family camping trip.

I’ve read manga that left me on the edge of my seat with suspense and intrigue, but none have quite matched the rollercoaster ride that was “The Tale of Seiichi.” The story follows our protagonist, who faces a formidable foe in his own family. His cousin Shigeru pushes him perilously close to cliff edges, but it’s Seiichi’s mother who takes things to another level.

18 Solanin

MyAnimeList Score: 8.21

Best Seinen Manga With No Anime Adaptations
  • Written and illustrated by Inio Asano.
  • 2 Volumes, 28 Chapters.
  • Available in English via Viz Signature.

In 2005, the manga series “Solanin” by Inio Asano was serialized for a year in “Weekly Young Sunday.” The story revolves around two college graduates, Meiko and Taneda, who are struggling to find their place in life. Meiko works as an administrative assistant to cover her living expenses, while Taneda creates illustrations for a publishing firm. Feeling stuck in their monotonous routines, they decide to take a risk by supporting Taneda’s band. Unfortunately, their endeavor leads to unfavorable consequences. Similar to much of Inio Asano’s output, this manga didn’t get adapted into an anime.

Despite being made into a live-action film in 2010, the anime “Solanin” may seem unnecessary given director Takahiro Miki’s successful adaptation of its melancholic and frustrating themes. Miki’s breakout project showcased his ability to bring the manga’s emotions to life on screen. In addition to “Solanin,” Miki has directed live-action adaptations of “Ao Haru Ride,” “Love Me, Love Me Not,” and surprisingly, Robert A. Heinlein’s science fiction novel “The Door into Summer.”

17 Eden: It’s An Endless World!

MyAnimeList Score: 8.22

Best Seinen Manga With No Anime Adaptations
  • Written and illustrated by Hiroki Endo.
  • 18 Volumes, 127 Chapters.
  • 14 Volumes were published in English by Dark Horse Comics.

Hiroki Endo’s science fiction comic series, titled “Eden: It’s an Endless World,” was serialized in Monthly Afternoon between 1997 and 2008. A significant portion of this work was later released in the West through Dark Horse Comics. While other Monthly Afternoon comics such as “Vinland Saga,” “Oh My Goddess!,” and even “Yokohama Kaidashi Kikou” gained animated adaptations and OVAs, “Eden: It’s an Endless World” remained in print and relied on praise from publications like Wizard magazine and Newtype USA for recognition.

In today’s context, the storyline of Eden resonates more than it did in the 2000s. The novel is set in a world devastated by the Closure Virus, which claimed the lives of 15% of humanity and left many more disfigured. Elijah Ballard is among the lucky few who are immune to this virus, compelled to mature in a post-apocalyptic era where he confronts the powerful Propator Foundation and allies with mercenaries to safeguard his loved ones.

16 Shiori Experience: My Plain Self and an Odd Old Man

MyAnimeList Score: 8.40

Best Seinen Manga With No Anime Adaptations
  • Written and illustrated by Yu-Ko Osada and Kazuya Machida.
  • 22+ Volumes, 108+ Chapters.
  • Fan Translations only.

Seinen manga frequently explores the theme of unrealized dreams. Many mature readers can identify with this subject, as they may have once aspired to be successful athletes, actors, scientists, and so on, but ended up in less glamorous careers such as office work or retail. Shiori’s Story, for instance, shares a comparable experience of Shiori, a budding musician whose band showed potential, but had their dreams shattered when her brother abandoned them to pursue a solo career in Tokyo, leaving behind a pile of debts.

Ten years have passed, and Shiori is currently a dedicated teacher, working hard to settle the remaining debt left by her brother. However, her life takes an unexpected turn when she encounters the spirit of Jimi Hendrix! With his assistance, Shiori’s world becomes more vibrant and filled with music. She isn’t alone in her supernatural encounters, as she has also come across the spirits of other renowned musicians, including Kurt Cobain, Prince, Janis Joplin, and Brian Jones, who was a founding member of the Rolling Stones.

15 Holyland

MyAnimeList Score: 8.45

Best Seinen Manga With No Anime Adaptations
  • Written and illustrated by Kōji Mori.
  • 18 Volumes, 182 Chapters.
  • Fan Translations only.

If “Our Dreams at Dusk” seems too sugary for some taste, this manga offers a grittier alternative. “Holyland” by Kōji Mori was serialized in the same magazine as “Berserk” during the 2000s. The story follows Yū Kamishiro, an outcast who endures bullying at school. Feeling disillusioned, he quits and finds solace among the lawless streets. There’s a certain allure to the chaos that resonates with him. He hones his combat abilities, particularly a boxing-style punch, and earns the moniker of ‘Thug Hunter’.

With every conquered rival, his strength amplifies, bringing him closer to the pinnacle of his abilities – his personal “Holy Land.” Despite not being adapted into an anime, the series made its way onto live-action TV screens. First in Japan for a 13-episode run in 2005, and later in South Korea for a 4-episode production in 2012. Mori currently helms “Berserk,” succeeding the late Kentaro Miura, making this an intriguing watch for fans of the series to observe the difference in storytelling styles.

14 Our Dreams At Dusk

MyAnimeList Score: 8.47

Best Seinen Manga With No Anime Adaptations
  • Written and illustrated by Yuki Kamatani.
  • 4 Volumes, 23 Chapters.
  • Available in English via Seven Seas Entertainment.

Regarding “Our Dreams At Dusk” by Yuki Kamatani, this thought-provoking manga series spanned two publications, “Hibana” and “Manga One,” between the years 2015 and 2018. It garnered significant acclaim, with Comic Book Resources describing it as possessing “stunningly beautiful, symbolic artwork and an emotionally resonant narrative that leaves a profound mark.” Moreover, Erica Friedman, founder of Yuricon, deemed it indispensable for the LGBTQ+ community in Japan. Indeed, this poignant work sheds light on the experiences and challenges faced by individuals identifying within this demographic.

Tasuke Kaname, a teenage student, is unexpectedly outed when classmates discover gay content on his phone. Feeling humiliated, he contemplates suicide by jumping off the school roof. However, he hesitates upon seeing someone jump from a nearby building and survive. Curiosity draws him to this place, which turns out to be a safe haven where people can openly discuss their struggles. Over time, Tasuke becomes a frequent visitor and encounters other individuals identifying within the LGBTQ+ community. Through these interactions, he begins to embrace self-acceptance and his sexuality.

13 Spirit Circle

MyAnimeList Score: 8.48

Best Seinen Manga With No Anime Adaptations
  • Written and illustrated by Satoshi Mizukami.
  • 6 Volumes, 45 Chapters.
  • Available in English via Seven Seas Entertainment.

Based on Satoshi Mizukami’s previous successful works such as “Lucifer and the Biscuit Hammer” being adapted into productions, it’s likely only a matter of time before “Spirit Circle” is picked up as well. Contrary to its seemingly cute cover, this story is about vengeance, atonement, and making things right. The narrative revolves around Fuuta Okeya, a high school student who can see spirits and bears a scar on his cheek.

As I gaze at my new classmate Kōko, her ghostly companion named East never leaves her side, and the identical scar above her brow mirrors my own. I’m captivated, believing I’ve found a soulmate. However, things take an unexpected turn as Kōko sets her sights on me, ready for revenge over a past incident that escapes my memory. With Rune, my enigmatic new ally, by my side, I must delve into the depths of my past to uncover the truth about my abilities, the significance of these scars, and make amends with Kōko.

12 Billy Bat

MyAnimeList Score: 8.49

Best Seinen Manga With No Anime Adaptations
  • Written by Naoki Urasawa and Takashi Nagasaki.
  • Illustrated by Naoki Urasawa.
  • 20 Volumes, 165 Chapters.
  • Fan Translations only.

From 2008 to 2016, I was deeply engrossed in “Billy Bat,” a captivating historical mystery thriller published monthly in Morning magazine. As a dedicated gamer and avid comic book fan, this series about classic characters and their creators held me in its grip.

From that point on, the situation becomes increasingly complex as he finds himself ensnared in a intricate plot involving murder, conspiracies, and a prophecy centered around the enigmatic Billy Bat character. The implications of which may reach deeper than one might initially think. This outlandish setup bears resemblance to Paranoia Agent, where fact and fiction overlap. Nonetheless, its captivating 20-volume run successfully hooked readers and garnered numerous accolades.

11 Hirayasumi

MyAnimeList Score: 8.51

Best Seinen Manga With No Anime Adaptations
  • Written and illustrated by Keigo Shinzō.
  • 7+ Volumes, 67+ Chapters.
  • Available in English via Viz Signature.

Although the story is soft and healing in nature, it doesn’t exclude it from being a seinen manga. Keigo Shinzō’s Hirayasumi, which debuted in Weekly Big Comic Spirits in 2021, shares the same magazine as “I Am A Hero” and “Oyasumi Punpun.” This manga follows Hiroto, a man who passes his days working part-time and conversing with townsfolk. He developed an exceptional bond with one resident named “Granny” Wada. When she unexpectedly passed away, she bequeathed her house to him in her will.

Three months following Hiroto’s arrival, his lively cousin Natsumi, en route to art college, decides to move in with him. Despite their stark contrast in personalities, they manage to coexist harmoniously in their humble abode. This isn’t a chilling psychological horror tale, but its endearing atmosphere and captivating narrative have garnered it a Tezuka Award nomination and accolades from Inio Asano.

10 Watashitachi no Shiawase na Jikan

MyAnimeList Score: 8.51

Best Seinen Manga With No Anime Adaptations
  • Written and illustrated by Sumomo Yumeka, adapted from a novel by Gong Ji-Young.
  • 1 Volume, 8 Chapters.
  • Fan Translations only.

As someone who has struggled with deep sadness and despair throughout my life, I can deeply connect with the story of “Watashitachi no Shiawase na Jikan,” or “Our Happy Time.” This manga offers a unique perspective that is rarely explored in media targeted towards young audiences: the idea that hope and connection can be found even amidst mutual depression.

Her aunt Monica, a nun who extends this unique opportunity to her, is the only family member involved. Sister Monica invites our protagonist to offer counseling to condemned prisoners at death row, aiming to broaden her perspective. The protagonist consents and encounters Yuu, a murderer with multiple attempted suicide attempts in his cell. Yuu dismisses Monica’s assistance as insincere pity. However, through interactions with Juri, they discover common ground. This manga is thought-provoking, as Yuu is far from an innocent soul, and it explores disturbing themes. Yet, like its inspiring source novel and film adaptation titled “Maundy Thursday,” it refuses to back down from the harsh realities, instead choosing to persevere through the suffering.

9 Usogui

MyAnimeList Score: 8.54

Best Seinen Manga With No Anime Adaptations
  • Written and illustrated by Toshio Sako.
  • 49 Volumes, 541 Chapters.
  • Fan Translations only.

An unusual situation arises with Usogui, as it indeed underwent an animated transformation. Specifically, Soft Garage created an OVA for Volume 26, covering the Hangman Game and Terrorist of the Abandoned Mine storylines. Nevertheless, these arcs were significantly condensed to accommodate a single hour-long episode. Consequently, numerous characters and subplots were omitted from the final product. The latter arc also obtained an adaptation in the form of a VOMIC (Voiced Motion Comic), which is essentially a motion comic sans animation.

As a die-hard gamer, I can tell you that the captivating storyline of “Usogui” or Baku Madarame, didn’t just make it to a live-action movie under the brilliant direction of Hideo Nakata. But if you truly want to experience every intricate detail and nuance of this rollercoaster ride, you need to dive into the original manga.

8 A Bride’s Story

MyAnimeList Score: 8.56

Best Seinen Manga With No Anime Adaptations
  • Written and illustrated by Kaoru Mori.
  • 14+ Volumes, 111+ Chapters.
  • Available in English via Yen Press.

Kaoru Mori is well-known for her “maid stories,” with “Emma: A Victorian Romance” being her most renowned work. This piece has influenced numerous “Emma”-themed maid cafes and an anime adaptation. Interestingly, Mori’s earlier creations, such as “Shirley,” remained set in the 1900s England era. However, following “Emma,” Mori’s subsequent work unexpectedly shifted to Central Asia. Initially published in “Harta” Magazine and later transferred to “Aokishi,” A Bride’s Story essentially embodies its title.

Amira’s tale centers around her journey from her secluded village to marry Karluk, which involves crossing the mountains using the ancient Silk Road. During her travels, she encounters various women from different tribes, who share insights into their lives with their future husbands and spouses. Mori painstakingly portrays the details of Central Asian life, cultures, and traditions during the mid-1800s, as well as the experiences of women living within these societies.

7 Lone Wolf And Cub

MyAnimeList Score: 8.63

Best Seinen Manga With No Anime Adaptations
  • Written by Kazuo Koike.
  • Illustrated by Goseki Kojima.
  • 28 Volumes, 142 Chapters.
  • Available in English via Dark Horse Comics.

The samurai story “Lone Wolf and Cub” by Kazuo Koike and Goseki Kojima, featuring Ogami Ittō’s quest for revenge against the Yagyū clan while caring for his son Daigorō, resulted in six films. Two of these movies were merged to create the 1980 release “Shogun Assassin,” which gained infamy and was eventually censored due to its graphic violence. The series also inspired various TV shows, movies, a video game titled “Samurai Assassin,” and even a board game.

Although its Hollywood film adaptation remained dormant, and it inspired shows such as “The Mandalorian” and the movie “Road to Perdition,” “Lone Wolf and Cub” never transformed into an anime. The most it approached animation was through some animated sequences for a 2012 pachinko game. Instead, it has been referenced and spoofed extensively across various series, including “Urusei Yatsura” and “Samurai Champloo.”

6 The Climber

MyAnimeList Score: 8.78

Best Seinen Manga With No Anime Adaptations
  • Written by Shinichi Sakamoto and Yoshirō Nabeda, based on a novel by Jirō Nitta.
  • Illustrated by Shinichi Sakamoto.
  • 17 Volumes, 170 Chapters.
  • Fan Translations only.

The Climber, or Kokō no Hito (“Solitary Person”), is unique as it began life as a novel. Written in 1973, it was one of the last works by Jirō Nitta, a historical fiction author whose oeuvre earned him the Naoki Prize for literary achievement, a Purple Ribbon for his artistic contributions, and a 4th Class Order of the Rising Sun. So, Shinichi Sakamoto and Yoshirō Nabeda had a tall order to fill when adapting it to manga.

In the weekly comic “Young Jump,” Mori Buntarō’s story unfolds. His goal: reaching the summit of K2, the world’s second-tallest mountain and a notoriously challenging climb for even the most skilled professionals. The manga delves into Buntarō’s backstory and motivation for climbing, making it as much about his character development as his quest to conquer K2’s peak. Sakamoto’s breathtaking illustrations of this arduous journey add an extra layer of captivation.

5 REAL

MyAnimeList Score: 8.94

Best Seinen Manga With No Anime Adaptations
  • Written and illustrated by Takehiko Inoue.
  • 15+ Volumes, 97+ Chapters.
  • Available in English via Viz Signature.

For over two decades, the thought-provoking manga REAL has graced the pages of Weekly Young Jump. A valuable point of comparison, it highlights the distinction between seinen and shōnen genres. In contrast to shōnen sports manga that primarily focus on exhilarating actions for drama and excitement, seinen manga like REAL place greater emphasis on character development. With its leads, Nomiya, Togawa, and Takahashi, REAL explores their struggles in a world that has left them behind.

Takahashi served as the captain of his basketball team until an unfortunate accident left him with paralysis from the waist down. Togawa was on the brink of becoming Japan’s fastest sprinter, but unfortunately, he had to undergo an amputation due to an incident. Nomiya devotes himself to caring for a woman who became disabled in an accident that he believes was his fault. They discover a new path in life through wheelchair basketball, but it’s not an easy journey as they must confront the challenges of their disabilities and past traumas.
