On one of his early-morning excursions to photograph the sunrise, Yorito meets a strange girl engaged in an argument with a vending machine. By the time that Yorito forces the girl's tomato juice out of the machine, she's vanished without a trace. Sola follows the story of Yorito, his sister Aono, and their childhood friends Mana and Koyori Ishizuki, as well as that of a mysterious girl who appears and disappears, and who seems to harbor a dark secret.
