The official Twitter account of Daisuke Ashihara’s World Trigger manga has announced that the manga will not appear the August 2020 issue of Shueisha’s Jump SQ. magazine due to Ashihara’s poor physical health. The manga is scheduled to return in the September 2020 issue.
Shueisha’s Jump SQ. magazine published part of the World Trigger manga’s 197th chapter’s content as a rough-draft version due to the creator’s health. VIZ Media published the draft digitally on June 3, 2020.
Ashihara debuted the manga in Shueisha’s Weekly Shonen Jump magazine in 2013, and VIZ Media publishes the series simultaneously digitally. Ashihara took a one-week break in September 2014 to treat the nerve roots affected by cervical spondylosis (wear and tear on neck area of spinal column), and then took several one-week breaks due to sudden illness.
The manga went on hiatus in November 2016 due to Ashihara’s poor physical health, and returned in Weekly Shonen Jump in October 2018 for five issue before moving to Shueisha’s Jump SQ. magazine in December 2018. The manga then took a one-month break in June 2019 so that Ashihara could recover from intestinal obstruction complications that arose from his recent gall bladder removal surgery. The manga took another one-month break in November 2019 due to Ashihara’s poor physical health.
