Setsuna rises up to create a future for a city without hope, but tragedy strikes time and again. Meanwhile, Rinne finishes her invention and Setsuna sets out for the future to save mankind’s existence.  Just before he goes, Setsuna makes a promise to Rinne.
But I don't want you to leave.
لكن لا أريدك أن تغادر
Aber ich will dich nicht verlieren, Setsuna.
Pero no quiero que te vayas.
Pero no quiero que te vayas.
Mais je ne veux pas
que tu disparaisses…
Ma non voglio che tu te ne vada.
Mas eu não quero que você vá.
Но я боюсь тебя потерять.
