Yukiya agrees to accompany Natsuka to the underworld. The negotiation threatens to fall apart when Sakuō appears and offers Yukiya a chance to learn more about the monkeys. However, to do so, he must take a great risk.
That's what the Underground is about.
.هذا هو جوهر العالم السفلي
So machen wir das hier in der Unterwelt.
Así somos en el Subsuelo.
Así son las cosas en los Bajos Fondos.
Voilà comment c’est,
dans les Souterrains.
È così che funziona la Città Sotterranea.
Esse é o espírito aqui no Subterrâneo.
В этом вся суть Подполья.
