Haruka Ozora

From Harukana Receive. She is Kanata's first cousin through her mother's side. She comes to Okinawa because of her parents' employment, and although initially Kanata is distant from her, they quickly become friends thanks to beach volleyball. Haruka is a rather light-headed and open person, so she often emotionally reacts to people and events around her. She also tends to admire Kanata and from time to time give her ambiguous compliments, but this trait was removed in the anime.
