Nukitashi the Animation

After the death of their parents, Junnosuke Tachibana returns to Seiran Island with his younger sister Asane and finds the place transformed by a law that aggressively enforces sexual participation. To Junnosuke, intimacy without love is not freedom, and his refusal to comply immediately makes him a problem for the authorities who police the island's new order.

When Nanase Katagiri unexpectedly helps him escape the Seirantou Health Organization, Junnosuke discovers that he is not the only person resisting. He joins a clandestine movement determined to abolish the law and protect those who cannot oppose it openly. On an island where private behavior has become public policy, even a small act of refusal can expose the entire rebellion.
