Fifteen years after the summer vacation. If we didn't go to the Digital World. If I didn't make this trip with others. If we didn't change at all like this. These Digimon were always with us. We've been friends all the time. We learned the importance of helping each other. All the things have made us what we are! New stories for all the "DigiDestined" in the world. Taichi, seventeen, high school days.
After years of inactivity, the DigiDestined regroup with their Digimon to save their world, but have the years changed their characters too much?
The DigiDestined go to a nearby hot springs theme park and everyone has a good time, but Joe doesn't show up because he wants to study for his exams. Another infected Digimon, Ogremon, attacks Odaiba. Gomamon runs away from home while Mimi faces problems with the other DigiDestined and her classmates because of her selfish ideas.
After seeing Meicoomon's abrupt transformation and killing of Leomon, Agumon and the other Digimon are kept isolated in Koushiro's office in order to prevent them from infection, but signs of infection begin to appear in Patamon.
Upon arriving at the Digital World after the "reboot", the Digidestined are hunted by a new villain. Meanwhile, Sora is troubled by her partner Digimon's indifference towards her.
Meicoomon rampages after witnessing Meiko Mochizuki being injured by the man bearing Gennai's likeness. "It would have been better if you hadn't been born..." Meicoomon disappears into the Real World, which has since become distorted. Possessing overwhelming power, she's the key to the world's destruction.
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?
