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.

وإلّا لما واصل مقاتلة الكاباني 
.من أجل الباكوفو لعشرة أعوام
Sonst hätte er wohl kaum zehn Jahre lang
die Kabane für das Shogunat bekämpft.
Si no, no habría combatido Cadáveres
Si no, no habría combatido Cadáveres

Altrimenti negli ultimi dieci anni...
Ou ele não teria lutado com os
Cadáveres pelo shogunato por dez anos.
Иначе бы он не сражался последние
десять лет с мертвыми ради сёгуната.
