A Contest of Love

Sora wants Ginjiro to put the blue girl behind bars to prevent anymore murders of females in the streets. When Seikichi and Oise see Sora and Ginjiro at the riverbank, they assume that these two are dating. During a test launch, the nozzle of the rocket is able to maximize the thrust velocity, but the wooden barrel explodes due to the internal pressure of the nozzle. After Shunpei figures out that the barrel must be made of iron, it is learned that tickets will be sold in an underground lottery for the launch. As both Ginjiro and Akai find out who was responsible for distributing the tickets, the old man sends out a group of cats to gather the tickets to be burned. A clock tower bell is used for another test launch, but it starts ringing due to the internal pressure.
