Lena, an elite Republican soldier, is assigned as the new commanding officer, also known as a “handler,” to oversee the Spearhead Squadron. Lena despises the social caste system of the Republic that looks down on the Eighty-Sixers as “subhuman pigs,” and treats them as human beings. With Shin leading the young Eighty-Sixers on the battlefield and the talented and promising elite Lena offering tactical support from the rear, they stand on the front lines constantly on the brink of life and death.

Despite living in a class based-society where a pureblood such as Lena should have never crossed paths with someone of mixed race like Shin, the two of them break down social constructs and continue to fight for a brighter future.
