Natsuki Subaru, an ordinary teenager, meets a beautiful girl with blue hair and red eyes from another world. Subaru wants to stay by her side, but the burden she carries is greater than Subaru can imagine. They face fierce attacks from monsters called 'Angels', betrayals, irrational violence... and, ultimately, death. Subaru promises to defeat any enemy, any fate, anything to protect her. And so, he will have to join NERV to protect those he knew and loved, and for that, he has 'Return by Death'.
