Nothing was expected of them. Then they were called upon to be the heroes they never had. Within hours of the invasion of Hokkaido by the Russian Empire, a new generation of soldiers, unrecognizable from their forebears, were dispatched into brutal combat not seen since the Second World War. After eight years, they are broken and weary for all they know of an adult's life is despair, death and fear. Corporal Suzue "Suzi" Kobayashi is one of these so-called heroes. Described as lively, kind and curious by her old classmates and the most cold-blooded killer in the entire 75th Ranger Regiment by her comrades. With no interest in the world that will rise from the ashes of war, she dies and gets reincarnated into a fantasy world similar to the role-playing games she used to grind on school weekends. Battle-hardened and weary, she wonders if there is a future for her anywhere. Can she find peace in a world where no one understands her? Where her life is so unfamiliar to her new comrades?
