With funds dwindling, Kotaro dispatches the girls to a Ureshino hot spring resort to secure a pharmaceutical sponsorship. Following a sightseeing tour and discussions about their idol aspirations, the group finds that the promoted skin patches effectively relieve their muscle stiffness, enhancing their performance. However, that night, Sakura, Saki, and Junko disobey Kotaro’s orders and enter the hot springs. They are discovered in their true forms by the pharmaceutical company’s president, causing her to flee in terror. This exposure leads to the immediate cancellation of the sponsorship deal, leaving the group without the financial support they desperately needed.
