Marginal Operation Vol. 4
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. The life of a private mercenary is far more grueling than he could have ever imagined!
