The manga will be back in the June issue of Jump SQ.
The official Twitter account for the Jump SQ. magazine revealed on Monday that World Trigger will not be appearing in the May issue (released in Japan on April 4) of the magazine due to the manga creator's Daisuke Ashihara health. World Trigger previously took a break in the March issue (which released in February) due to a sudden illness. The tweet once again confirms that Ashihara does not have COVID-19.
