Seita is a kid who makes his living through pickpocketing. One day Seita picks Gintoki’s wallet only to find it pretty much empty, and discovers that his own wallet was picked back in return. In the end Seita treats Gintoki to some parfait after getting caught red-handed. Brought into Snack Otose for questioning, Seita shocks everyone by revealing he needed the money to see a certain “遊女/Yujo (courtesans/ prostitute).”
