Digimon Adventure tri. Reunion

Three years have passed since the gate to the Digital World was sealed. Taichi Yagami and his friends have moved on with their lives, now navigating their second year of high school. While most of his peers have clear aspirations, Taichi remains uncertain about his future, and his friendships have begun to fray as everyone pursues their own paths. Suddenly, a rogue insectoid Digimon named Kuwagamon emerges, wreaking havoc on the city's electronics. Impulsively, Taichi gives chase, only to find himself cornered by the menacing Digimon. Just as hope seems lost, his Digivice, a digital device that serves various purposes, including aiding Digimon evolution, illuminates. Agumon, Taichi's faithful Digimon partner, appears, and together, they defeat Kuwagamon. However, the question remains: why did Kuwagamon cross over to this world? What is happening in the Digital World, and how is Meiko Mochizuki, the new transfer student, connected to these events?
