Yū tries to recall a tasty ramen she ate in Osaka when she was a kid, which turns out to be a dish literally called Tasty Ramen. After Yū and Koizumi go to a Tokyo branch at Kabukichō to try the dish, Koizumi goes on a ramen pilgrimage to Osaka where she encounters a woman named Ayane. Serving as Koizumi's bodyguard against guys trying to pick her up, Ayane accompanies Koizumi during her remaining ramen stops. Hearing about how Ayane is due to leave Osaka after quitting her job, Koizumi takes her to a ramen restraurant that she remembers from her childhood, but is later slightly disconcerted upon discovering that Ayane is actually Yū's cousin.
