In the aftermath of World War Three, Viktor Sokolov, a former Neo-Soviet KSSO operative, found himself adrift in a shattered world. The once-thriving Baltic states lay in ruins, and both NATO and the Neo-Soviet Union had been left crippled by the brutal conflict. During the chaos of war, a new weapon had emerged: Tactical Dolls-advanced combat units that fused cutting-edge robotics with sophisticated AI, created to fill the growing need for adaptable and precise soldiers when human forces alone could no longer meet the demands of battle. With national armies weakened and new threats rising from the ashes of global warfare, traditional military powers struggled to maintain control. In their place, private military companies filled the growing void. Among the most prominent of these was Griffin & Kryuger, a PMC built on the promise of security in a fractured world. For Sokolov, joining G&K was more than a career choice-it was a lifeline. Haunted by the weight of his actions and the lives lost during the war, he saw in G&K a chance not only to apply his skills but to rediscover the purpose that had slipped through his grasp amid the senseless destruction. In a world dominated by private interests and mercenary alliances, Sokolov's journey became one of personal redemption-searching for meaning, direction, and a way to reconcile his past with the uncertain future ahead. For him, it wasn't just about surviving in this new world. It was about finding out if he could live with himself in it.

Pyotr Romanovich was a veteran of multiple wars, that had claimed many of his brothers-in-arms, and his mental stability. Having moved to the far-eastern city of Vladivostok, he thought he would live out his life in quiet peace, dealing with his inner demons and trauma on his own, only to find himself surprised when an old acquaintance suddenly dials him and asks to hire him. Not as a bodyguard like many other former Russian soldiers who had left the military, but as an advisor to a school that wishes to re-establish its Senshado Team. Reluctant but intrigued, Pyotr agrees to become the senshado advisor of Oorai Girls' Academy's fledgling team, led by Miho Nishizumi of the Nishizumi bloodline. Through countless training sessions and the forging of new friendships, Pyotr helps the team rise to new heights, all while healing his wounded soul. From a war-weary veteran to a beloved mentor, he realized that, amidst the shadows of the past, there is always a chance for renewal and hope; and further realized that his unexpected role as an advisor of a school with an unorthodox doctrine had given him a family and a future worth fighting for once again.
