Arrival in Okinawa and separation

Takato and Henry arrive in Okinawa for their summer trip. They part ways: Takato stays with his cousin Kai and his grandfather, while Henry heads to explore the underwater ruins offshore. This separation kicks off parallel adventures that drive the coming events.

Global V-Pet virus outbreak

V-Pets cause technical viruses that sweep across computer networks worldwide. The spread disrupts systems everywhere and demonstrates the scale of the threat. Takato and the others realize the crisis is larger than a local incident.

Team travels to the island where Minami is held

Takato and his friends travel toward an island where Minami is held captive. They prepare to confront the mastermind behind the V-Pet threat. The journey marks a shift from discovery to direct confrontation.

On the island, Minami's father reveals that the prototype laptop carries a vaccine program. He also uncovers that Tameshiro, the V-Pet company head, is a Digimon named Mephistomon who sent Digimons to capture Minami. The revelation links the crisis to a singular villain.
