Da Capo II - Plot

Plot

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. Years later, though, the tree starts malfunctioning, granting all wishes, regardless of how impure. Sakura and Otome Asakura at first try to handle all the problems caused by it, but the situation gradually worsens and they have to choose whether or not to save Hatsunejima (初音島?)—the island in Japan where the story takes place—by deactivating the tree which would erase Yoshiyuki's existence in the process. Sakura makes a last-ditch effort to stop the tree by entering it directly, but fails. Yoshiyuki eventually manages to persuade Otome to choose the island over him, and she has the tree wither, revoking all the granted wishes, including Sakura's.
