As reports come in of a flasher in the city, Milky Holmes encounters a girl named Coron from Osaka, who gets them to help her investigate the culprit. The girls come to suspect the Gentlemen Thieves and confront them with an odd method that ultimately fails, whilst Stone River comes at Hercule, suspecting her to be the flasher. Finding herself in a strange part of town, Hercule is targeted by a flasher but manages to knock her out, revealing her to be Coron, whose real name is PÅ. Wanting to experience the freedom of being naked, the others decide to take her to a bathhouse, whilst G4 capture the true culprit.
