The February 2021 issue of Kodansha’s Afternoon magazine has announced that Yūri Shibamura and Daisuke Kimura’s Marginal Operation manga will end in its next issue.
The story of Marginal Operation is described as:
Our hero Ryouta Arata is an otaku who’s just lost his job after the dissolution of his company. Unwilling to return to his old NEET ways, he applies online to a private military security company, thinking the benefits to be promising. After what appears to be a baffling test, he’s assigned to be an \”operator of operators\” and begins his training in a foreign country. Little does he know, the life of a private mercenary is far more grueling than he could have ever imagined.
The Marginal Operation manga launched in Kodansha’s Afternoon magazine in 2013. J-Novel Club is publishing the manga in English.
