Following NERV's failed attempt to retrieve the Spears of Longinus and carry out the Human Instrumentality Project, the destruction caused by the Fourth Impact has been largely averted. In a state of disarray, Shinji Ikari, Asuka Langley Shikinami, and Rei Ayanami travel to Village 3—a survivor settlement free from Earth's ruination. There, Shinji slowly comes to terms with his past, developing an entirely different life from his days as an Evangelion pilot. Meanwhile, NERV makes preparations to continue the Instrumentality Project by means of a new Impact. When WILLE's main aerial battleship arrives at the village, Shinji decides to board, believing that he can help by piloting an Evangelion. As new secrets are uncovered and a battle between WILLE and NERV approaches, the future of Earth hangs in the balance. Can Shinji save humanity and the rest of the world one last time?

When the threat of the Angel menace escalates, mankind's defense force is pushed to its limits, with NERV at the forefront of the struggle. Shinji Ikari and his partner Rei Ayanami are assisted by two new pilots: the fiery Asuka Langley Shikinami and the mysterious Mari Illustrious Makinami. With the aid of their mechanized Evangelion units, equipped with weapons perfect for engaging their monstrous opponents, the four young souls fight desperately to protect their loved ones and prevent an impending apocalypse. But when startling secrets are brought to light, will the heroes' greatest challenge prove to be the monsters...or humanity itself?
