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.
I can't believe we came back.
لا أصدّق أننا عدنا
Hier sind wir wieder …
No puedo creer que regresáramos.
No puedo creer que hayamos vuelto.
Je pensais pas revenir ici.
Non riesco a credere che siamo tornati.
Eu não acredito que voltamos.
И вот мы опять здесь.
