From the wikia: "A new netbattling tournament has opened for the world, called the Battle Chip GP. Yai Ayanokoji is sponsoring the event while the others enter it. Even Eugene Chaud enters the tournament, but only for official business. It turns out that there is some type of new organization behind the scenes of the tournament who will delete the winning NetNavi and take its data for themselves. Will Lan Hikari and friends be able to stop whoever is behind these threats?"
