Kodansha’s Magazine Debut website has published Hajime Isayama’s “Jinrui VS Kyojin” one shot manga. The then-19-year-old Isayama submitted the manga to Kodansha’s Magazine Grand Prix contest in 2006, and it won the “Fine Work” award. Before that, he had submitted the manga to Shueisha’s Weekly Shonen Jump magazine, but was rejected.

Isayama launched the main Attack on Titan manga in Kodansha’s Bessatsu Shōnen Magazine in 2009. Kodansha Comics is publishing the manga in English.
