Da Capo

Da Capo is a Japanese adult visual novel. Da Capo centers around Jun'ichi Asakura, who lives with his adopted sister Nemu on Hatsune, a fictional crescent-shaped island where cherry blossoms bloom all year long, where they attend Kazami Academy (風見学園, Kazami Gakuen) high school. On this island, people have mysterious powers and attributes, sourced by the unwilting magical cherry tree. Jun'ichi can see other people's dreams. One of his friends, Kotori Shirakawa, is an idol at the school who can "read minds". One day, to Jun'ichi's surprise, his cousin Sakura Yoshino comes back from America all of a sudden, who looks exactly the same girl that moved away six years ago, and has not aged one bit. She returned to remind Jun'ichi of their childhood promise.
