A digi-egg found its way to Chika, and Piyomon hatches from it. The two became instant friends. Later, Masaru is told that regular people can't keep digimon as partners unless they're DATS members. This torn Masaru up since he doesn't want Chika to be in danger by becoming a DATS member. Meanwhile, a new digimon - Falcomon appeared in the human world to claim the digi-egg back and found out that it's hatched into Piyomon. Now it wants to bring Piyomon back to the digital world.
