Soukyuu no Fafunâ: Heaven and Earth plot
Things have gotten desperate for Kazuki. Nearly blind, and partially paralyzed from his battles with the Festum two years earlier, he holds on to his fallen friend Soushi's promise to return to the island to set things right. One night, Kazuki gets a glimmer of hope when a life form is detected in an unmanned submarine floating in Tatsumiya Bay. However, the person on board is not Soushi; it is a mysterious "boy" named Misao Kurusu who may not be fully human, and claims to have been sent by Soushi. With Misao's arrival, previous disputes between the human army and the Festum are rekindled. The Fafner pilots are thrown into the most desperate battle of their lives, this time with the fate of two races on their shoulders.
