Ayame is one of Kasumi's sisters, along with Sakura and Botan. She's the second oldest of the four sisters. In Hanada Gym! Underwater Battle! it is stated that Ayame writes the sisters' water shows; however, a later episode shows Sakura performing this task. She sometimes also plays the part of the mermaid as seen in Kasumi and Lovecus! Love Battle!. Along with Botan, she seems to tease Kasumi more than Sakura.
