Karakara published the original Donten ni Warau manga in Mag Garden's Monthly Comic Avarus magazine from 2011-2013. Karakara launched the Donten ni Warau Gaiden manga on Mag Garden's "Beat's" manga site in 2014, and ended the series in February 2017.
The original manga's story takes place in the 11th year of the Meiji era, when the number of people in Japan who feel dissatisfaction toward the government are increasing due to the increasing speed of Westernization and the ban on samurai. In order to curb the increased rate of crime, the government opens a new prison. The three brothers of the Kumo family are entrusted with the duty of transporting these criminals to the new prison, but adventures await them on the way.
The Donten ni Warau Gaiden manga inspired a trilogy anime film adaptation. Donten ni Warau Gaiden: Ketsubetsu, Yamainu no Chikai (Parting, The Oath of the Yamainu), the first film, opened in Japan in December 2017. Donten ni Warau Gaiden: Shukumei, Sōtō no Fūma (Fate, The Double-Headed Fūma), the second film, opened in Japan in June 2018. Eleven Arts screened both films in the United States in August 2018.
The third film, Donten ni Warau Gaiden: Ōka, Tenbō no Kakyū (Cherry Blossoms, the Bridge to Heavenly Wishes), opened in Japan on September 1 and screened for two weeks. Eleven Arts will screen the film this year.
