Old Paths Intertwine... With Arata's own allies, the Burmese army, terrorizing the local population, he quickly realizes he must take care of internal affairs before focusing on the Chinese. He works to save the local villagers from their own government, with his efforts eventually leading him to Yangon. He not only meets the UN peacekeeping team being detained there, but finds himself in an unexpected reunion as well...

No Place Like Home... A year has passed since Arata took the child soldiers under his wing - after discovering they were on the receiving end of his orders. In that time, he has toured numerous battlefields across Asia, while doing his best to provide for the kids under his care. Fed up with forcing them to continue to fight just to survive, Arata takes them to Japan in hopes that his peaceful homeland may provide a solution to the dilemma he faces.

Arata had come to accept the weight of his life-or-death decisions, but with his own life on the line for once, will he be able to keep his cool under fire? Even as he faces this new challenge, his mastery of battlefield tactics has caught the attention of a mysterious group of combatants in this endless war. Will he live to fight another day?

Good Friends, Better Enemies... Arata believed his travails in Thailand were over, but Kishimoto had other plans. The moment Arata let his guard down, his former colleague struck, kidnapping Hakim and Sophie. For the first time, Arata has to contend with the possibility that someone under his command might die. Will he crack or will he be able to operate effectively under such pressure?

Reunions abound... Arata succeeds in securing more funds from his sponsors and is now able to procure the anti-aircraft weapons he so desperately needs. However, before he can, he encounters previous friends and enemies alike. Laying his old grudges to rest, Arata then moves forward with fighting back against China's aerial forces. No amount of victories will return the lives he's already lost, but he can't afford to stop in his tracks or risk incurring more casualties.

Pushing foreign borders... In accordance with his sponsors' wishes, Arata finally makes a move against the Chinese army. Initially, things are going well, and he's able to recapture multiple villages without any casualties. But while it seems his momentum is unstoppable, Arata soon discovers this conflict is far more complicated than he originally thought...

With Arata's training camp now complete, he's sent off to his first official post as a PMSC employee. Determined to atone for the sins he unwittingly committed, he tackles his new job with zeal, trying his best to keep as many people alive as possible. Unfortunately, the mercenary life is a harsh one, and the darkness within PMSC runs far deeper than Arata could have ever imagined. Can he stay true to his ideals despite coming face-to-face with the horrors of war?

The fires of vengeance burn on... With Arata's battle against his former employer now concluded, the situation has finally begun to stabilize. During this time, after careful deliberation, he decides to accept Miss Li's request and begins recruiting child soldiers from Thailand's slums. However, unbeknownst to Arata, while his rival company may have decided to back out for now, there are still those within it who hold a personal grudge against him, and they won't rest until they've had their revenge.

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 battle in Myanmar rages on fiercer than ever before. China has deployed their helicopters and drones, while Arata’s allies, the Burmese Army, turn out to be far less reliable than he'd hoped. It will take the full extent of his considerable wit to continue winning his battles and keeping his kids alive. Fortunately, by rescuing the nearby villagers from their own government's tyranny, he may have inadvertently created the perfect strategic opportunity for himself.
