Plot
In Hikarigaoka, Tokyo, a boy named Yagami Taichi wakes up late at night and sees his little sister Hikari looking at their dad's computer. Suddenly, a strange egg comes out of it. The next morning, While their mother is out, the egg seems to develop a mind of its own when it escapes Hikari's grasp and rolls away. It then hatches into a Botamon and immediately latches onto Taichi's face. Taichi throws it off, and it runs under the nearby bed. Taichi tries to get it out by throwing his googles at it, but that just makes Botamon blow bubbles at him. Hikari eventually gains its trust with her whistle and begins feeding it chocolate, causing it to evolve into Koromon.

Now out of food, Hikari steals the food belonging to their cat, Miko, and gives it to Koromon, who thanks her by latching onto her face as well and then Taichi's. Miko soon finds Koromon with its food, however, and lashes out. Taichi tries to protect him but Miko retaliates but scratching him and Koromon, and takes his food back. By the time their mother is back, Koromon introduces himself to Hikari and talks with her, surprising Taichi that it can talk. He tells Taichi and Hikari that he is a Digimon from the Digital World. They don't really understand this and later head to bed, but Koromon suddenly evolves into a big Agumon and begins roaming the streets, causing destruction on a small scale, while carrying Hikari on his back.

Agumon is roaming around the city causing trouble while Taichi frantically chases after him and Hikari. Before he manages to cause any real casualties, a Parrotmon appears out of a huge egg in the sky. Agumon lashes out, which only angers the bird, causing it to destroy an overhead bridge and covering Agumon and the two kids in rubble. Out of the rubble, Red Greymon appears in Agumon's place and begins fighting back against Parrotmon. After a few minutes, Greymon is knocked out, and only awakens when Taichi blows Hikari's whistle as loud as he can. He then lets out a blinding fire breath attack, and the two Digimon vanish, leaving Taichi and Hikari alone among all the destruction. Ishida Yamato, Takenouchi Sora, Izumi Kōshirō, Tachikawa Mimi, Kido Jō, and Takaishi Takeru all see the battle from their windows and are chosen as the Chosen Children along with Taichi and Hikari four years later.
