However, Yamazaki trips and they fall to the minefield getting blown up. The "Panties Thief" appears shortly after and goes for the panties only to be stopped by some Shinsengumi officers on the rooftop led by Yamazaki. At that moment the group realizes that no one remembers where they planted their mines and that they are trapped at their hiding spot. Kondo volunteers to get something cold for them to lower the heat, but he steps in one of his mines and is knocked out.
Driven from the agony of waiting the thief's arrival, everyone starts to fight with each other. They have tied a pair of Otae's panties in the courtyard outside, with the ground filled of mines. They start a hard and serious training for the upcoming night, when they lay a trap for the thief. Back in the dojo Otae, the Yorozuya gang and the Shinsegumi have gathered to make a plan to arrest the thief. However, Kondo denies the accusations and shows them a newspaper about the "Panties Thief" terrorizing the city recently, stealing panties and giving them to the city's hopeless perverts, like Robin Hood. Gin and Shinpachi then discover Kondo under the table stalking Otae as usual and suspect him of being the " Panties Thief". Kagura agrees to help Otae and they go away to get a drink.
Shinpachi informs the rest of the Yorozuya that Otae has been attacked by a " Panties Thief" when he was away at the Yorozuya for the past two days. She rips apart the lucky charm, before explaining to Shinpachi the reason he surprised her and why she is so upset. Otae attacks him and almost stabs him with a spear. Shinpachi buys a lucky charm, which he names Stephan, from an Amanto before he visits his sister, Otae at their dojo. The Yorozuya and Shinsengumi team up to take down a harassing "Robin Hood" stealing women's panties.
