Tai is now a university student, living alone, working hard at school, and working every day, but his future is still undecided. Meanwhile, Matt and others continue to work on Digimon incidents and activities that help people with partner Digimon. An unprecedented phenomenon occurs and the DigiDestined discovers that when you grow up, your relationship with your 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 you fight for others only to lose your partner? The time to choose and decide is approaching fast. There is only a short time before the “chosen children” will become adults. This is the last adventure of Tai and Agumon.
