Artist Shoji Sato said in an interview that media news website Natalie published last week that he plans to end the Triage X manga at around its 21st volume.
Sato launched the manga in Kadokawa’s Monthly Dragon Age magazine in 2009, and Kadokawa published the 18th compiled volume on December 7.
The manga inspired a television anime series in 2015.
Sato also drew the art for Highschool of the Dead, another manga that inspired an anime.
