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?

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?

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.

Foreign Shore Trouble... After leaving Japan, Arata ends up drifting to Thailand. His fame has continued to grow, and now there is no one in the mercenary world who hasn't heard of the famous Headmaster. However, all he wants is to find a place where he can raise his children in peace, and not have to send them to war just to earn a living. Will this south asian nation finally provide him with an opportunity to do so, or will he be forced to fight again?

Going on the Offensive... With the Chinese Army presenting an overwhelming difference in firepower to his own forces, Arata employs guerrilla tactics to successfully take out a key refueling base. However, this enrages the Chinese Army more than expected, leading to an air strike against Camp Hakim in retaliation. With the Burmese Army still disorganized and his sponsors unwilling to lend further aid, the only person Arata can rely on to get them out of this mess is himself.

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...

An Ill-Fated Encounter... Driven insane by the loss of his daughter and the death of Hakim, Kishimoto turned on his coworker and killed him in cold blood. After this, he used Sophie to goad Arata into a final showdown at a park in Thailand. From training camp comrades to bitter adversaries, how will this confrontation end as their two paths collide?

A Storm is Brewing... Having come to Thailand in the hopes of finding a way to support his children without forcing them onto the battlefield, Arata instead finds himself being asked to recruit more children from the slums and expand his mercenary operations. It may be the only way to save them from being exploited by a far more predatory company, but he still feels conflicted about sending yet more children to war. Will he be able to escape this industry before it claims the lives of his precious kids?
