Nukitashi THE ANIMATION

Seiran Island is a tropical paradise trapped in an endless summer, but beneath its idyllic surface lies a society driven to madness. Following the tragic death of their parents, Junnosuke Tachibana returns to his family’s ancestral home on the island alongside his sister, Asane. However, he quickly discovers that Seiran has been radically transformed by the implementation of the "Perverted Law," a drastic government mandate designed to combat severe population decline. Under this extreme legislation, public indecency is not only permitted but actively encouraged, and any citizen who refuses to participate in reproductive activities faces punishment nearly as harsh as a serious criminal offense. A fiercely proud virgin and staunch advocate for chastity, Junnosuke finds himself entirely at odds with the island's new reality. Refusing to accept the legitimacy of a law that strips away personal autonomy, he resolves to protect both his own purity and that of his beloved sister from the island's pervasive corruption. To fight back against the oppressive regime, Junnosuke establishes the anti-copulation resistance group known as NLNS—No Love No Sex. With unwavering determination, he sets out to dismantle the Perverted Law once and for all, vowing to restore sanity to Seiran Island no matter the cost.
