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.
