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.
What could the Underground desire 
more than a Northern hostage?
ما قد يبتغيه العالم السفلي أكثر
من رهينة من الشمال؟
Für die Unterwelt sollte eine Geisel
der Nordfamilie verlockend sein.
Un otage du Nord doit être pour vous
une proposition plus qu’alléchante.
Ritengo che per la Città Sotterranea, un ostaggio
del casato Nord sia una pedina preziosissima.
O que o Subterrâneo deseja mais
do que um refém do Norte?
Больше всего на свете Подполье желало
заполучить наследника Северного дома.
