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 you'll remember me, right?
لكن ستتذكّرني، صحيح؟
Pero seguirás recordándome, ¿no?
Pero seguirás recordándome, ¿no?

pour toujours, hein ?
Ma tu ti ricorderai di me, giusto?
Mas você se lembrará
de mim, não é?
Но ты всегда будешь помнить о ней.
