Yuuichi Aizawa, a high school student, returns to a town that he last visited 7 years previously to live with his aunt and cousin. For a reason he’s not quite sure of, he can hardly remember anything about his last visit, but initially this doesn’t seem to worry him too much.
The day after he arrives he goes into town where he (literally) bumps into a girl named Ayu Tsukimiya, and Yuuichi’s memories slowly begin to return.
Kunisaki Yukito's deceased mother left him with the doll and her last wish that Yukito look for the "girl in the skies" because it is his destiny to save her. Only half-understanding what his mother meant, Yukito has been traveling across Japan, vainly searching for this myth-like girl his mother told him about. His latest destination is a small, sleepy town where summer has just arrived; and his encounter with a young girl named Misuzu there sets the wheels of destiny turning....
Tomoya Okazaki is a third year high school student at Hikarizaka Private High School, leading a life full of resentment. His mother passed away in a car accident when he was young, leading his father, Naoyuki, to resort to alcohol and gambling to cope. This resulted in constant fights between the two until Naoyuki dislocated Tomoya’s shoulder. Unable to play on his basketball team, Tomoya began to distance himself from other people. Ever since he has had a distant relationship with his father, naturally becoming a delinquent over time.
While on a walk to school, Tomoya meets a strange girl named Nagisa Furukawa, questioning if she likes the school at all. He finds himself helping her, and as time goes by, Tomoya finds his life heading towards a new direction.
