In an underground shelter-city encased in ice, Setsuna meets a young girl named Rinne and begins helping her with a mysterious invention. It can apparently help save the world, but its true nature is unclear. Meanwhile, the city itself will very soon perish.
Until that day, let us live 
with love in our hearts.
إلى أن يحين ذلك اليوم، لنعِش بحبٍّ في قلوبنا
Lasst uns, bis es so weit ist,
Hasta entonces, vivamos con amor
en nuestros corazones.
Hasta entonces, vivamos con amor
en nuestros corazones.
En attendant, vivons ensemble
en nous aimant les uns les autres.
Fino ad allora, viviamo col cuore colmo di amore.
Até esse dia, devemos viver
com amor no coração.
Так будем же с любовью к ближнему
ждать назначенного часа.
