The official Twitter account for Shueisha’s Jump SQ. magazine has announced that Daisuke Ashihara’s World Trigger manga will not appear in the magazine’s November 2021 issue on October 4, 2021, 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. World Trigger is planned to resume in the December 2021 issue, which will ship in early November 2021.
The manga also took breaks in the March 2021 and May 2021 issues.
Ashihara debuted World Trigger in Weekly Shonen Jump magazine in 2013. 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 issues before moving to Shueisha’s Jump SQ. magazine in December 2018. VIZ Media is publishing the manga in English.
