Although it isn’t common, there are a lot of reasons why an author might allow someone else to work on or complete their manga series. They could want to work on other projects, prioritize their health, or see how another author interprets their world. However, it’s most common that a manga series will be continued by someone else after the original author passes away.
Without the efforts of the second author, the manga may otherwise remain incomplete, but that doesn’t make their job simple. Interpreting and replicating the style, plot, and intent of a manga for fans takes time and respect. Luckily, some beloved series were able to manage the transition.
10 Berserk
Kentarou Miura’s passing was one of the most painful losses for manga fans in 2021. His masterpiece, Berserk, made an everlasting impression on the community for its detailed art style and complex character-driven plot. The thought that Guts’ traumatic and compelling story would never reach its intended conclusion was heartbreaking.
Although some fans of the Berserk series can’t believe that the series would continue without Miura, others have accepted and appreciate the level of detail that Miura’s friend, Mori Kouji, and the other Berserk staff have been putting into the story since his passing. Each chapter the team has released has been better than the last, making fans optimistic about a fantastic ending.
9 Souten Kouro
Souten Kouro follows the last Chancellor of the Eastern Han Dynasty during the Three Kingdoms period and his attempts to break China’s reliance on tradition. The series began in 1994, written by Hagin Yi and illustrated by King Gonta. However, Yi passed away in 1998 due to cancer, leaving the series to Gonta.
The series tied with Gambling Apocalypse: Kaiji for the general category of the 22nd Kodansha Manga Award in 1998, and Gonta continued the story until its completion in 2005. Between its award and its longevity, Souten Kouro remained well-received throughout its publication.
8 Doraemon
Doraemon is one of the most iconic manga made for kids. The famous robotic cat created by Fujiko F. Fujio (real name: Fujimoto Hiroshi) and Fujiko A. Fujio (real name: Motoo Abiko) made children laugh while sometimes teaching life lessons. The duo went separate ways in 1987, but Fujiko F. Fujio continued working on the series until he passed away in 1996.
Since then, the series has been picked up by Fujiko Pro, a production company made up of assistants who worked on Doraemon alongside the original creators. Fujiko Pro has released several successful spin-off series, anime movies, and tv shows.
7 Ajin: Demi-Human
In 2012, Tsuina Miura and Gamon Sakurai worked together to create a dark and disturbing story about immortal people with the ability to summon violent demons. However, they only collaborated on Ajin: Demi-Human for a short time before Tsuina Miura decided to pursue another project, High Rise Invasion, at the start of 2013 .
Starting from the second volume, Gamon Sakurai became the writer and illustrator for Ajin: Demi-Human. By the end of 2013, His work on the series made it top the charts and helped it win third prize in a competition hosted on Comic Natalie. Its success continued to be celebrated in 2014 when it was nominated for the 18th Annual Tezuka Osamu Cultural Prize and the 38th Annual Kodansha Manga Awards. Ajin: Demi-Human also became an anime at the start of 2016.
6 Saint Seiya (Knights of the Zodiac)
Saint Seiya, sometimes known as Knights of the Zodiac, was created by Masami Kurumada. It follows an orphan on a quest to find his sister and become a great warrior known as a saint. The original series was completed in its entirety by Kurumada.
However, Saint Seiya has a few spin-off series where other authors were given the creative freedom to shape the world how they pleased. It is most well-known that this was the case for Saint Seiya: Episode G by Megumu Okada and Saint Seiya: The Lost Canvas by Shiori Teshirogi, two prequel series. Kurumada expressed his confidence in the other authors for both spin-offs, and each sold thousands of copies shortly after being released.
5 Crayon Shin-chan
Crayon Shin-chan was created by Yoshito Usui and is one of the most famous comedy manga and anime series ever released. He began the series in 1990 and continued sharing the silly adventures of a young boy named Shin-chan until he died in 2009.
Following his death, Usui’s assistants and production team published unreleased manuscripts, allowing the original Crayon Shin-chan to continue through the start of 2010. The assistants began a sequel to the series, New Crayon Shin-chan, later that year. Altogether the manga series has sold over 145 million copies worldwide, while the anime has become one of the longest anime series of all time.
