The Shogunate closes off the path to Kongokaku because they are wary of Biba and the support he's managed to garner. Biba seeks an audience with the Lord of Iwado Station, though with less than pure intentions.
I won't let you be mean and 
keep us outside the walls.
.من غير المنصف أن يبقونا خارج هذه الجدران
Ich sorge dafür, dass ihr Fieslinge uns nicht
vor den Mauern versauern lasst.
No es justo que nos dejen fuera.
No es justo que nos dejen fuera.
C’est pas juste
qu’on soit les seuls dehors.
Non vi permetterò di essere ingiusti 
e di lasciarci fuori dalle mura.
Não deixarei que vocês sejam
maus e nos deixem do lado de fora.
Нечестно, что только нас не пускают.
