Suzumiya, Akane

涼宮茜

Haruka's younger sister. She initially views both Takayuki and Mitsuki as older siblings until she discovers they have been seeing each other behind Haruka's back. While Haruka is in the hospital, she visits every day because there is no one else to keep her company, even though Haruka is in a coma. This demonstrates just how much she loves her older sister. Like Mitsuki, she is a powerful swimmer in her own right, but feels as if she can never match Mitsuki. Her intense hatred towards Mitsuki after the accident can be attributed to the feeling of personal betrayal by someone she considered an idol for throwing away her (Mitsuki's) talent and dreams, as well as Mitsuki's betrayal of her sister through her sexual relationship with Takayuki. She learns to move on in life and becomes a top swimmer in Japan.
