The undying sakura trees return. The story once again takes place on Hatsunejima , but is set 53 years after the events of D.C. and D.C.S.S. . Although some characters will probably look a bit familiar to the initiated eye, the cast is a new one. The two new main protagonists are the Asakura sisters Yume and Otome , who are the granddaughters of Jun'ichi and Nemu from the first season.
