Kaze no Tani no Naushika

One thousand years after the Seven Days of Fire, an apocalyptic war which destroyed modern human civilization and the world's ecology, the earth is covered by the Sea of Corruption, a vast forest of fungi and plants that give off poisonous miasma and is inhabited by large deadly insects. Life in this world is most difficult for humans, but humans are still fighting over the small portions of inhabitable lands left to them around the edges of the Sea of Corruption. A war is about to break out between the Kingdom of Torumekia and the Dorok Empire, and Nausicaä, the princess of a small country, The Valley of Wind, now has to leave the Valley to join the Torumekian army, which is about to invade the Dorok Empire.

Although she is a skilled warrior, she hates killing, and is torn between the duty as a chieftain of her people and her love for every living creature, including Ohmu, the huge insects who protect the forest. Nausicaä's true desire is to solve the mystery of the Sea of Corruption, and find the "Blue Pure Land", a place where people can live without being threatened by the poison from the Sea of Corruption.

Through her desperate attempt to prevent anyone from being killed, she stumbles onto the secret of the Sea of Corruption. But this is just the beginning of her long, hard journey. In the end, she has to face the true secret of the world in which she lives and make a very difficult decision about the ultimate fate of the entire world.
