Rika, Kazu and Kenta are transported away by the light. They lose their consciousness and wake up to find the globe has become tiny. That means they’ve been transported far away from where they were.

A series of earthquakes occur in and around the West Shinjuku area. Takato and Henry have a bad feeling about this.

Henry and friends are searching for the secret of Blue Card, when tough enemies Pajiramon and Vajiramon appear. As Gargomon falls into a pinch, Henry overcomes his hesitation and slashes his Blue Card. Gargomon digivolves to his ultimate self, Rapidmon, and destroys the two Digimon taking advantage of his amazing speed.

Separated from Rika, Renamon is in a solidtary battle with without support. Bothered about Renamon, Rika turns her back against him believing he doesn't need her any more. However just in a reach of victory, Renamon stops moving, Renamon also cares about Rika and he becomes doubtful of fighting alone.

Forbidden to digivolve, Terriermon is being cornered by Gorillamon’s powerful attack. However Henry has the tact to produce Digi-Modify and it turns the tide.

The moment Takato's Card Reader reads data of Blue Card, the door to adventure opens in front of him. And then he encounters his fatal partner Guilmon. Now the new digital journey begins with the Shinjuku as the backdrop.

In Carnel Sphere, the core of D-Reaper, Beelazemon has been unable to move with his four bound by countless cords. Jeri has still been sitting with her legs in her arms and with blank looks.

The one who suddenly appears on the roof of a building in South Shinjuku like a hero is a Mega Digimon called Justimon. Knowing Takato and friends were in a fix, he has rushed up to the scene. But why should he? When Justimon raises his hand in cool and smart way, Rika recognizes who he is.

Was that actually Jeri Takato sees? Takato thinks it is strange and calls the house in Matsumoto she is staying. To his surprise Jeri has disappeared from the house. Besides he hears it happens just about the same time when Takato saw her.

In front of Takato and friends in DigiWorld appear the ship called Ark sent by Henry’s father and staff in co-operation with people all over the world. They have no time to lose. In order to go back to the real world, they rush on board except Rika and Renamon who have been away looking for Impmon.

The real enemy is found out to be D-Reaper; the program for eliminating Digimon. It is to erase Digimon one after another not to mention dust packets. 4 Sovereign Digimon tighten their guard.

There is a straight line of countless arches from Nandaimon Gate to somewhere far beyond. Takato and friends set out for Suzakumon where Zhuqiaomon lives leaving Kazu, Kenta, Guardromon, Shu-Chong and Jeri behind.

WarGrowlmon has digivolves into Mega level. However he looks completely different from what Takato fancied. Did it happen because Takato got so furious when Leomon is killed that he wished too much for his digivolution?

Shu-Chong has been missing Terriermon. While she is playing in a park, a zone appears out of the blue and she falls into it. Then she finds a gigantic rabbit-like Digimon in the place she reaches.

Suddenly the ground turns into liquid state under their feet - Kenta, Kazu, Jeri, Rika, Renamon, Leomon and Guilmon sink, to find themselves in a small world of ancient Japan.
