Having learned the truth about This World, groups led by Ms. Aki and Hoshi prepare to go their separate ways. Nagara finds himself in an upside-down world he cannot freely leave, and is forced to work on building a Tower of Babel that reaches downward.
Heaven is the way out,
back to our own world.
الجنة هي سبيلنا للخروج 
 .والعودة إلى عالمنا
Der Himmel ist der Ausgang
in unsere ursprüngliche Welt.
El cielo es la salida,
de regreso a nuestro propio Mundo.
C’est la sortie pour rentrer
dans notre monde.
O Paraíso é a saída,
de volta para nosso mundo.
