In the game, Takato Matsuki and Guilmon find that Henry Wong and Rika Nonaka have had their Digimon kidnapped to serve the Master. The two discover through Impmon that the source of the disturbance is at the Sewers, but hordes of Digimon guard the place, so they have to assemble the secret device. It's up to Takato and Guilmon to investigate the source of this incursion and stop whoever is controlling all of the Digimon.
