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.
Up and down doesn't matter to them.
They do as they please.
.لا يهمهم إن صعدوا أو نزلوا
 .إنهم يفعلون ما يحلو لهم
No les importa si van arriba o abajo.
Hacen lo que les place.
Não importa a direção.
Só fazem o que bem entendem.
