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 February 2022 issue on January 4, 2022, due to the author’s poor health. The manga is scheduled to return in the March 2022 issue, which will ship on February 4, 2022. The manga also took breaks in the March 2021, May 2021, and November 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.
