The October 2018 issue of Shogakukan’s Monthly Shonen Sunday magazine has announced that Q Hayashida will launch a new series titled Dai Dark (Great Dark) around spring 2019. The taglines for the manga read, “Space, planets, epic adventure” and “Darkness spreading infinitely.”
The same issue published the final chapter of Hayashida’s Dorohedoro manga. The science-fiction manga first debuted in Shogakukan’s Monthly Ikki magazine in 1999. When Monthly Ikki ended publication in 2014 the manga moved to its replacement magazine Hibana, and then to Monthly Shonen Sunday when Hibana ceased publication in 2017.
