Looking up at the heavens, what do you notice? A clear blue expanse? The promise of liberty? An optimistic tomorrow? Residents of Tokyo perceive none of these. Instead a foreboding extraterrestrial flagship hovers above, swallowing the skyline.
Three years past, they arrived. The entrance of the "Invaders" ignited the most devastating conflict humanity had ever endured—one that risked annihilating the planet. The Japanese authorities rushed to confront them. Arms were produced en masse, igniting debate and sparking pacifist campaigns.
That instant altered everything. Yet nothing truly shifted. Kadode Koyama and Ouran Nakagawa spend their remaining days as they always have: attending school, mingling with peers, and engaging in the carefree rituals of a typical high‑school girl.
As they mature, they discover what it truly means to be an adult in a realm where adults appear as malevolent beings that merely deceive and destroy. They learn the genuine danger to humanity lies not in the Invaders, but within humanity itself.
