Characters » Suzumiya Akane
Haruka's younger sister initially treats both Takayuki and Mitsuki as older siblings until she finds out they have been seeing each other behind the comatose Haruka's back. While Haruka is in hospital, she visits her every day. She, like Mitsuki, is a competitive swimmer, but feels as if she can never match Mitsuki, who she initially looks up to. Later, there are hints given that Akane feels something more for Takayuki, but these are not explored fully in the series.
