After all Takato, Henry, Rika and their partner Digimon have come back to West Shinjuku, where appear mysterious creatures they haven’t seen before. Could they be D-Reaper?

A mist spreads out on a crossing road. Sensing the appearance of Digimon, Terriermon gets ready to fight, but Wong doesn't allow him. Terriermon insists, but Wong tries to force him home.

Guilmon’s true Mega-self, Gallantmon was born.

"You are also Digimon tamed by humans." What Indramon says hurts Impmon's pride. Impmon refuses Renamon and others' help, and then throws himself into a reckless fight alone.

Thanks to Dobermon, Takato, Henry and Rika are now able to make their partner Digimon evolve into Mega level again. They realize evolution in the real world with each wish in mind.

Because of Guilmon, Takato’s school is in a panic. Being told he is unworthy as a tamer, Takato is hurt and loses his confidence. Yet he is consoled by Guilmon’s innocence. Takato and Guilmon become friends with each other, getting over all these troubles.

In co-operation with 4 Sovereign Digimon, Takato and friends succeed in saving Calumon finally. However D-Reaper’s bubbles boil and make them tense again. It seems their real enemy is ready to attack seriously.

Because of the appearance of Digimon, the real world is engulfed into chaos. Now the damage caused by Digimon is the nation’s big problem.

Shaggai, who is supposed to eliminate Digimon, ironically opens the way for Digimon to come into the real world. A powerful enemy who thus appears, beating Kyubimon and Gargomon one by one with overwhelming power.

Selected out of many candidates to be Rika’s partner, Renamon pledges himself to become the most powerful Digimon. However he fails to digivolve no matter how many times he fights and that makes Rika irritated more.

In D-Reaper’s zone, Jeri wakes up and she’s been suffering cornered by a D-Reaper that imitates her looks. Calumon desperately tries to save her from the suffering.

Takato and friends, who come back from DigiWorld safe and sound, leave Tokyo with each family except Jeri whose family doesn't come to pick her up. Takato sends Jeri to Matsumoto. On his way back, he sees a news program on TV where dark red slimy D-Reaper is\ encroaching on skyscrapers in Shinjuku.

In spite of MegaGargomon’s attack, something sparkles under a pile of rubble and with streams of scarlet light in all directions appears Zhuqiaomon like a phoenix. Takato and friends become speechless to see invulnerable Zhuiaomon.

Lopmon tells Takato and Henry that there is a domain of 4 Sovereign Digimon where Calumon is supposed to be. Although Takato proposes they should go there, Henry is reluctant. He doesn’t want his little sister Shu-Chong involved.

Takato and friends who get separated from Rika go back to the spot where they flew the banner, just to find the banner has dissapeared.
