The recluse son of the Mashiroi Gang boss, Kaguzo, is hiding a shocking secret! Upon hearing the details, Gintoki points his sword at Nakamura. Attacked by retaliating gang members, Gintoki escapes and hides. Kaguzo collapses due to illness and the Mashiroi gang’s successor will soon be announced. Just as Nakamura is about to be crowned as Kaguzo’s successor, Gintoki suddenly barges onto the scene…
Like I told you, I only came to fulfill my
obligation to honor and humanity.
Ya te lo dije, estoy aquí por 
mi sentido de la justicia.
Como eu disse, só vim cumprir minha
 obrigação de honra e humanidade.
