Taichi Yagami and his companions have graduated to junior high, but they have lost contact with their Digimon partners by then. As a result, Taichi is taken aback when he receives a distress call inviting him to the Digital World. When he arrives, he discovers that Digimon are terrified of the mysterious Digimon Emperor, who is apparently inhibiting their ability to Digivolve! Hikari Yagami and Takeru Takaishi re-join the same fifth-grade class in the real world. They have three classmates in common: Daisuke Motomiya, who reminds them both of Taichi; Miyako Inoue, a technological whiz; and Miyako's neighbor, Iori Hida. When these three youngsters obtain "D-3" Digivices, they become the next generation of "Chosen Children," along with Hikari and Takeru, who still have their original Digivices.
