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 mean we'll go back to before they died!
!أعني سنعود إلى قبل موتهما
Darum müssen wir was ändern,
bevor sie gestorben sind!
¡Hay que volver a antes de que mueran!
¡Hay que volver a antes de que mueran!
Alors il faut les sauver
avant qu’elles meurent !
Per questo torneremo a prima che morissero!
Podemos voltar para antes
delas terem morrido!
Поэтому попробуем не дать им умереть!
