Meiko Mochizuki faces a chilling reality when her Digimon companion, Meicoomon, undergoes a malevolent transformation into Meicrackmon, succumbing to a dark influence. As Meicrackmon vanishes, leaving chaos in its wake, signs emerge that the Digital World rejects Meiko and her fellow Chosen Children. Fleeing relentless adversaries, the group seeks a way back home. Simultaneously, in the human realm, representatives from the enigmatic entity Homeostasis approach Meiko's father and Daigo Nishijima from the Administrative Agency to delve into Meicoomon's enigmatic genesis. Homeostasis discloses its intention to eradicate the digital creature to halt further Digimon manifestations in the human domain, indifferent to the Chosen Children's sentiments.
