16 Manga Creators Who Died Before Finishing Their Life's Work

One harsh reality about adulting is that you have to hear news about the death of a friend or relative. Whenever it happens, there's the question of mortality that haunts us. What's sadder is that even the source of joy and solace isn't exempt from life's final cycle. The mothers and fathers of our beloved manga and anime shows will also have to meet their final curtain.

Unfortunately, not everyone will be given a chance to finish their life's work, like these manga creators 

who passed away too soon, leaving drafts and illustrations pending on their desks.

Talk about hitting someone's heart with two stones:

Firstly, the story you're following every week will no longer reach its conclusion. As such, you'll never see your favorite characters in a new scene again, and you'll try to satiate your cravings by re-watching the anime. If you couldn't get out of the obsession, you might start campaigning for someone else to continue the dead mangaka's work, which is a hopeless case, as there haven't been many unfinished novels that we know of. If nothing feeds your fantasy, the ghost of the unintendedly killed series will haunt you for a long time.

Secondly, the poor mangaka-sensei died, and that alone is devastating already. A successor may replace him, but nothing compares to that artist who inspired people with elements only he can deliver. As the legacy continues, you remain unsatisfied with what you see because you believe that the story could go better if it were the original Sensei who still runs it.

When you discover a good anime with no conclusion, you'll realize how bad it feels compared to a hiatus.

If a manga author like Yoshihiro Togashi puts Hunter x Hunter on a break for the nth time, fans know that he'd be back again. Moreover, updates, crossovers, and new merch appear just around the corner from time to time.

But when the mangaka suddenly dies while their novel is at its climactic point, the impact will cut deep into the hearts of many fans. Think about what will happen to the world if Oda dies before finishing One Piece.

We bring this heartbreaking discussion to you, as it indeed happened. Read on to learn more about these manga creators who perished before they could finish their life's work.

#16 - Keiko Tobe — With the Light: Raising an Autistic Child

source: Reddit

Keiko Tobe created With the Light, one of the most humane, quietly devastating manga ever written about parenting, disability, and the kind of exhaustion that doesn’t look dramatic until it swallows a whole household. The series didn’t end on a neat “final chapter” moment. It stopped because her body stopped cooperating.

Tobe died in 2010, and With the Light was left unfinished. That’s what makes it sting. The entire manga is built around long-term growth, patience, and the idea that progress can be slow but real. Then it’s cut off mid-journey, like life interrupting the very message the story was trying to protect.

#15 - Cocoa Fujiwara — The Magical Girl and the Evil Lieutenant Used to Be Archenemies

Cocoa Fujiwara had a gift for romance that felt soft without being empty. The Magical Girl and the Evil Lieutenant Used to Be Archenemies looks cute on the surface, but it’s the kind of story that slowly hooks people because the emotional tone is strangely sincere for something that playful.

Fujiwara died in 2015, and the manga was explicitly left unfinished afterward. That’s why it reads like a series that was about to deepen even more, then freezes in place. It doesn’t collapse. It just… ends where it shouldn’t.

#14 - Daisuke Satō — Highschool of the Dead

Highschool of the Dead isn’t just remembered for zombies and chaos. It’s remembered because it stopped right when it felt like the story had bigger turns coming. Fans waited through long pauses, still hoping the series would come back with a proper continuation.

It never did. Daisuke Satō died in 2017, and after that, the decision was made to leave the manga unfinished. It’s one of those cases where the title feels cruelly literal in hindsight. The apocalypse kept moving, but the author didn’t.

#13 - Hinako Ashihara — Sexy Tanaka-san

Hinako Ashihara’s Sexy Tanaka-san is the type of manga that wins readers by being casual and real. It’s not shouting for attention. It’s the kind of story people read because it feels like someone understands the awkward parts of adulthood, identity, and trying to change your life without a clean reset button.

Ashihara died, and the manga was left unfinished because of it. That alone makes it qualify for your list, but what makes it hit harder is that the title character’s whole vibe is persistence. Small steps. Quiet confidence. Then the series ends without closure, like the universe refusing to give the character the ending she earned.

#12 - Kentaro Miura — Berserk

If the phrase “unfinished masterpiece” has a face in modern manga fandom, it’s Berserk. Kentaro Miura spent decades building a world that felt ancient and weirdly beautiful. Other than dark fantasy, it was endurance in manga form, the kind of series people carry through entire phases of their life.

Miura died in 2021, and Berserk was still incomplete when he passed. That’s the nightmare scenario for a fandom. Not because the story was “almost over,” but because it felt like it was reaching the part where everything would finally have to pay off. The tragedy isn’t only that he died. It’s that the story he poured his life into didn’t get to finish speaking in his own voice.

#11 - Noburo Yamaguchi (The Familiar of Zero)

With only 20 out of 22 chapters finished, The Familiar Of Zero is one of the ultimate cliffhangers after its creator, Noburo Yamaguchi died of an advanced stage cancer.

The mangaka amassed great popularity when he started his light novels Kaze No Kishime and Zero No Tsukaima (The Familiar Of Zero).

Yamaguchi went on hiatus due to a series of surgeries performed to thwart cancer growth. Before Yamaguchi's death in 2013, he was able to share the plot, including the ending of his life's work, The Familiar Of Zero to his editors.

Yamaguchi's family and his fans also wanted to see the completion of the said series. As such, Media Factory was able to release its 21st volume in 2016 and the last chapter in 2017.

#10 - Tomohiro Matsu (Hatena Illusion)

Known for his of light novels series such as "Listen To Me, Girls. I Am Your Father! (PapaKiki!) and "Mayoi Neko Overrun! (Stray Cat Overrun!)" These two novels with 18 and 12 volumes respectively became an anime series.

His last novel series, Hatena Illusion, remains unfinished after his death in 2016, due to liver cancer. Despite the short amount of content, the 4-novel series earned an anime adaptation in 2017.

#9 - Takeyuki Kanda (The 08th MS Team)

Famous for his outputs on Dragon Warrior, Metal Armor Dragonar, and Ultraman Anime, Takeyuki Kanda's demise makes another blow to the Japanese animation industry.

The 08th MS Team, an original video animation of Kanda, outlines the exploit of the Earth Federation Ground Unit during a year war. He worked half of the series (6 out of 12) before he died on July 27, 1996, due to a car accident.

#8 - Yoshito Usui (Crayon Shin-Chan)

Many fans were shocked by the untimely death of Yoshito Usui, the author behind the popular Crayon Shin-Chan series. The novel depicts the story of an adventurous five-year-old boy.

Usui went missing on September 12, 2009, from hiking in Gunma Prefecture. After a week, his dead body was found and identified. Three thousand people who knew him personally and loved his work attended his funeral service.

Yoshito Usui did not finish the manga and never intended to end it anytime soon. As such, the story remained hanging until Usui's team began a new Crayon Shin-Chan manga in 2010.

#7 - Shotaro Ishinomori (Cyborg 009)

Ishinomori became an influential manga artist, tokusatsu, and artist for his massive works such as Cyborg 009, Sabu and Ichi's Detective Memoirs, and Hotel. His name is also attached to other famous creations like Kamen Rider, The Legend Of Zelda, Power Rangers, and more.

In 1968 and 1988, he received a Shogakukan Manga Award for his works Sabu to Ichi Torimono Hikae and Hotel and Manga Nihon Keizai Nyumon, respectively. Ishinomori died of heart failure a few days after his 60th birthday. He died without resuming the famous Cyborg 009, but was resumed in 2012 with his original novel drafts, concept notes and sketches.

#6 - Ken Ishikawa (Getter Robo)

Getter Robo is another series that went on hiatus after an important production person's death. Go Nagai, co-creator of the said series, started the mecha show with his friend Ken Ishikawa, who illustrated and also wrote parts of the novel.

Getter Robo mecha revolves around the story of Hayato Jin, Ryoma Nagare, and Musashi Tomoe. They piloted three combat jets, named Jaguar, Eagle, and Bear, uniquely designed for them. If the three mecha joins together, they become a giant fighter robot.

In 2007, after a golfing event, Ishikawa collapsed and rushed to the hospital, but he was pronounced dead. Following that year, Naoto Tsushima continued Ishikawa's continuity of the series and released the manga entitled Getter Robo Hien: The Earth Suicide. The story of this new arc roots from the drafts and notes of Ishikawa before his death.

#5 - Kaoru Tada (Itazura Na Kiss)

Young Kaoru Tada started with a shojo genre as a highschool student. Her works feature love stories and usually revolve around a female protagonist and her love interest. Though it may sound cliché, fans never grew tired of her outputs, with many of them becoming immensely popular.

Some of her timeless novels include Tiinzu Burabo, Kimi No Na Wa Debora, and the unfinished Itazura Na Kiss (Mischievous Kiss).

Tada suddenly passed away due to a horrific accident. While moving to a new home, she accidentally hit her head on a marble table and fell into a coma. Three weeks after a long slumber, she passed away at a very young age of 38.

Itazura Na Kiss manga did not meet its finalization. But her husband gave the nod to its anime adaptation, which ended its story.

Tada's masterpiece inspired many novels and live-drama adaptations, which became popular in many Asian cultures. Her promising works are evidence of what she could have contributed further to Japanese culture, particularly in anime-romance niche if she only lived longer.

#4 - Umanosuke Iida (Towa no Quon)

Iida is a Japanese director, anime creator, and screenwriter who played a huge role in some of the most sought-after anime series such as Cowboy Bebop, Nausicaä Of The Valley Of The Wind, Lupin III Part III, and Towa No Quon, an unfinished project.

Towa No Quon is a six-film anime series that portrays the story of Quon, a leader of humans with distinct abilities who try to defend themselves from a secret organization, Custos, who seeks to hunt them down.

#3 - Satoshi Kon (Dreaming Machine)

Known for his dark creations and exploration of the human psyche, especially of fondness of female characters, Satoshi Kon arises as a one-in-a-billion talented artists. Some of Kon's most talked about animation include Paprika, Perfect Blue, Paranoia Agent, and the unfinished Dreaming Machine.

Dreaming Machine entails the story of three robots. Although the whole plot is not made public, it was reported to be a fantasy-adventure show many kids and adults would love. This anime could have been a promising project until his death shocked the whole world.

Satoshi Kon chose to remain silent and out of the public eye after being diagnosed with pancreatic cancer. His health quickly deteriorated after he learned of the disease and was embarrassed to appear in his emaciated state.

Kon recorded his last message for everyone, and his family uploaded it in his blog upon his death.

The Dreaming Machine remained canceled as of this writing. Madhouse production wouldn't mind continuing this project if a talented Japanese animation director at par with Satoshi Kon's ability came along.

#2 - Osamu Tezuka (Phoenix)

Known as "The Father Of Manga," "The Godfather of Manga," and "The God Of Manga," Osamu Tezuka's life's work and even his death made a significant impact on Japanese culture. Tezuka's unmatched output and unique redefinitions helped honed anime to what it is today.

Some of Tezuka's creations include Astro Boy, Black Jack, Princess Knight, Kimba the White Lion, Unico, Message to Adolf, The Amazing Three, and Buddha. Sounds familiar. Yes, we do remember a lot of them.

Phoenix, Tezuka's life work, consists of 12 books about independent stories that took place in different eras. One notable story involves a man's journey to attain immortality through the blood of a Phoenix. This attempt to a complete depiction of life's story started in 1956 and ended after his sudden passing in 1989.

Phoenix had its final chapter in the production, but they remained unfinished after Tezuka's death. The mangaka died of stomach cancer, and his last words were, "I'm begging you, let me work," which he utters after a nurse took away his drawing equipment.
