Unknown to everyone, the game connects actually with the Digital World and the players are raising Digimon in fact, but only a few Tamers may hear their voices and interact with them beyond the game. Taiga and his friends are sent to the Digital World when the enigmatic Mirei send them an email which should be responded with the expression "Re:Digitize". There, Taiga and the others should help Jijimon to rebuild the Primary Village, which had been losing population due to a crisis happened in the File Island.
