The protagonist, Yoshiyuki Sakurai, was born when Sakura Yoshino, weary of being alone for so long, wished upon a prototype artificial wish-granting magical sakura tree for a family. Similar to its predecessor, the story takes place on the same island, Hatsunejima, in Japan, and set fifty-three years after the original anime. The Asakura sisters are the granddaughters of Junichi Asakura and Nemu Asakura from the first Da Capo. Sakura Yoshino and Junichi are the only returning characters, and Nemu is the only other character to be mentioned by name.
