Mitsuba, Okita’s older sister, pays a visit to the Shinsegumi headquarters to announce her marriage. The squad members are shocked to see Okita’s change in attitude when in front of Mitsuba. The two spend some time together for the first time in years. Mitsuba, who has always looked after her younger brother since he was little, is worried if Okita is doing fine in the Shinsengumi. In order to reassure his sister, Okita introduces his “best friend” Gintoki to Mitsuba, but...
Well, spend some time alone together. You don't need us.
Bueno, pasen algo de tiempo juntos. 
Nosotros no somos necesarios.
Bem, fiquem um tempo juntos. 
Vocês não precisam da gente.
