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.
