Suddenly, the Digivice that he still carries—a digital device that serves various purposes including helping one's Digimon partner to evolve—glows, and Agumon appears. The two are able to defeat Kuwagamon, but why did the Digimon cross over to this world in the first place? What is happening in the Digital World, and how exactly does this involve Meiko Mochizuki, the new transfer student in Taichi's class?
