And Gin-san was a criminal who was supposed to have been beheaded by the Ikeda family in the past. The family head, Ikeda Yaemon, requests Odd Jobs to keep Asaemon safe. The ship prepared for them seems to sailing smoothly but gets stopped in its tracks by Okita and Hijikata's appearance. That's when Okita reveals to them all the facts of this case...
It was because I knew I was a 
demon that had to be punished.
بل لأنّي أدركت تشكّلي شيطاناً يجب الحكم عليه
Lo hice porque soy un 
demonio que debe ser castigado.
Foi porque eu sabia que era um 
demônio que tinha que ser punido.
