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.
Nothing can save someone 
once they're dead.
لا شيء يمكن إنقاذ شخص عندما يموت
Tote sind nicht mehr zu retten!
No existe remedio para la muerte.
No existe remedio para la muerte.
On peut pas sauver
des personnes mortes…
Non si può salvare qualcuno che è già morto.
Não dá pra salvar
alguém que já morreu.
Мёртвых уже не спасти,
понимаешь?
