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.
Just going back and saving them 
won't change the island.
مجرّد العودة وإنقاذهما لن يغيّر الجزيرة
Nur zurückzureisen und sie zu retten,
wird Island nicht verändern.
Regresar y salvarlas
no cambiará nada en la isla.
Regresar y salvarlas
no cambiará nada en la isla.
Si tu ne fais qu’aller
dans le passé pour les sauver,
Tornare indietro per un lasso così breve di tempo
e salvare loro non cambierà Island.
Só voltar no tempo e salvá-las
não vai mudar a ilha.
Вернувшись на пару дней назад,
судьбу Острова не изменишь.
