Seita was picking pockets to see Hinowa, the highest-ranked 遊女/Yujo (courtesans/ prostitute) in the underground 遊郭/Yukaku (Licensed Quarters) Yoshiwara Tougenkyo, where law has no meaning. But his picking act was all for the sake of seeing the mother he was separated from at a young age. To let Seita see Hinowa, Gintoki and the gang march into Yoshiwara Tougenkyo, where they receive a rough welcome by Tsukuyo – the head of Yoshiwara’s paramilitary force, “Hyakka.”
Why?! Why’re the para-military force after us?!
¿Por qué? ¿Por qué viene tras 
nosotros la fuerza paramilitar?
Por quê? Por que a força
 paramilitar está atrás de nós?
