Story
From wikia: "A new net fighting tournament has been opened to the world, the Battle Chip GP. Yai Ayanokoji is the sponsor of the event while the others are participating. Even Eugene Chaud is participating in the tournament, but only for official business. It turns out that there is a new organization behind the scenes of the tournament that wants to erase the winning NetNavi and claim its data for themselves. Will Lan Hikari and her friends be able to stop whoever is behind these threats?"
