The official Twitter account for Shueisha’s Jump SQ. magazine revealed on Monday that Daisuke Ashihara’s World Trigger manga will not appear in the magazine’s November issue on October 4, due to the author’s “sudden illness.”
The Twitter account posted a letter from Ashihara where he stated that his head/neck specifically is what is in poor health right now.
The manga will still appear on the cover of the November issue.
The manga went on hiatus in November 2016 due to Ashihara’s poor physical health, and returned in the magazine in October 2018 for five issue before moving to Shueisha’s Jump SQ. magazine in December 2018.
