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.
I don't know why, but I have 
that feeling in my heart.
لا أعرف السّبب، لكن ينتابني ذلك 
الإحساس في قلبي
Keinen Plan warum, aber dieses Gefühl
hatte ich schon immer tief in mir drin.
No sé por qué, pero no se me quita
esa sensación del pecho.
No sé por qué, pero no se me quita
esa sensación del pecho.
Je sais pas pourquoi,
Non so perché, ma ho sempre avuto
questa sensazione nel cuore.
Eu não sei o motivo, mas tenho
esse sentimento no coração.
Не знаю почему, но что-то внутри
ведёт меня к этой мысли.
