Shinpachi returns home with a gift for his sister—a doll that oddly resembles Elizabeth, with the name “Space Monster Stefan” printed on its chest. But what awaits Shinpachi is a deadly naginata swing by the raged Otae. While Shinpachi narrowly dodges the attack, Stefan falls prey to the naginata. As she tears Stefan apart, Otae explains the reason behind her fit. It appears the panty thief who’s recently been stirring things up in Edo city stole her panties. To soothe her sister’s anger, Shinpachi decides to ask for help from Gintoki.
Perhaps he won't come at all. I mean, not only today, but never!
Puede que no vaya a venir. 
No solo hoy, sino siempre.
Talvez ele não venha. 
Nem hoje nem nunca!
