4화: 치후사와 카에데가 빚을 갚기 위해 다이빙하고, 오이소가 문어 위협과 싸우는 에피소드

4

With Chifusa and Kaede coming up short on a food bill, they are forced to become divers by the restaurant's owner, Oiso. As Oiso laments how her large breasts keep her from diving properly, her assistant, Mizuki, is attacked by a large octopus which has been causing trouble for the village for years. The next day as everyone hunts for the octopus, Oiso is captured while saving Kaede from the octopus, so Chifusa dives in after her. With the octopus using Oiso as a shield, Chifusa uses the Breast Flow technique to attack the octopus without hurting Oiso, absorbing her breasts in the process. As the octopus attacks Chifusa before she can come up for air, Oiso uses her newfound freedom to kill the octopus, giving Chifusa the credit as thanks. (Source: Wikipedia)
