Tai is now a university student, living alone, working hard at school, and working every day, but with his future still undecided. Meanwhile, Matt and others continue to work on Digimon incidents and activities that help people with their partner Digimon. When an unprecedented phenomenon occurs, the DigiDestined discover that when they grow up, their relationship with their partner Digimon will come closer to an end. As a countdown timer activates on the Digivice, they realize that the more they fight with their partner Digimon, the faster their bond breaks. Will they fight for others and lose their partner? The time to choose and decide is approaching fast. There is a short time before “chosen children” will become adults. This is the last adventure of Tai and Agumon.

The world has begun to collapse. The rampaging Meicoomon absorbs Tailmon, who underwent a dark evolution, and changes form into the immensely powerful Ordinemon. In accordance with Yggdrasil's expectation, the real world is about to be engulfed by the Digital World. Meanwhile, Homeostasis considers Ordinemon to be out of control and puts into motion its final plan that will entangle the real world. Then the time comes for the DigiDestined to arrive at a final decision. What future do they choose for themselves?

After years of inactivity, the DigiDestined regroup with their Digimon to save their world, but have the years changed their characters too much?

The Digital World is becoming so overpopulated that the super computer Yggdrasill who governs the Digital World can no longer handle it. Its solution is Project Ark: to wipe out most of inhabitants with the X Program. Yggdrasill chooses a very small percentage to be moved to a new Digital World and then proceeds to destroy the old one. Some Digimon who were not chosen survive anyway, and they move to the new world with a rare gift known as the X Antibody; this antibody changes their appearance and makes them more powerful, while at the same time making them immune to the X Program. No longer in control, Yggdrasill uses the Royal Knights to destroy these X-Digimon, who are outcasts in the new Digital World.

Six months after the D-Reaper was destroyed, the Tamers are planning to throw Rika a surprise party, but Rika finds out. Suddenly a train-Digimon named Locomon begins to race around the tracks, causing havoc. The Tamers respond to this, as Takato digivolves Guilmon into Growlmon to stop the train Digimon but fails as Takato, Rika and Renamon get on it in an attempt to slow it down. The others, excluding Suzie, use a freight train to catch up with Locomon

The first story focused on Tai and Kari Kamiya four years before their adventure in the Digital World. It shows their first encounter with Digimon and what happened to them (as well as the other children). Tai and Kari wake one morning to find a Digi-Egg that came out of their computer the night before and the egg soon hatches, revealing a Botamon. The Digimon then evolves into Koromon and then Agumon (not the same one that became friends with Tai in the series, and yet, somehow, both Koromon and Kari remember each other), who then goes out and unintentionally destroys a good part of the neighborhood with Kari riding on his back. A second Digi-Egg appears in the sky to reveal an evil digimon, Parrotmon. Agumon then Digivolves to Greymon but isn't strong enough to beat Parrotmon and is knocked out. Tai grabs Kari's whistle and wakes up Greymon, who defeats Parrotmon and disappears with him.
