Born in 1970 in Tokyo, Japan, the young Oikawa Yukio was a shy and lonely boy. His only friend was Hida Hiroki, who was obsessed with the Digital World. The two made contact with the Digital World, and would spend hours and hours playing video games and interacting with Digimon through Hiroki's game console. Eventually, Hida Chikara, Hiroki's father, who was worried about their obsession and put an end to their contact with the Digital World. Although the boys were heartbroken, Yukio and Hiroki remained lifelong friends, vowing to one day visit the Digital World together.

As adults, Yukio became a geneticist, working along with Ichijouji Ken's father, while Hiroki became a police officer. Hiroki married Fumiko and had a son, Iori, though Yukio didn't have much contact with either of them. Even their new adult responsibilities didn't stop the two friends, who continued to work on finding a way to enter the Digital World.

In 1999, Yukio made arrangements to meet with journalist Takaishi Natsuko, who had been investigating the Hikarigaoka incident of 1995, meaning to discuss his hypothesis that Hikarigaoka was a gateway to the Digital World. However, in the summer of 1999, Hiroki was killed in action, taking a bullet for an important figure. Yukio was devastated, unable to get over the death of his only friend.

On August 3rd, 1999, he was on the pier at Tokyo Bay, watching tearfully as the Digital World appeared in the sky, while holding up Hiroki's picture. In his despair, watching the Chosen Children leave for the Digital World, he is manipulated by Vamdemon's disembodied spirit, which takes refuge in his body. From that day Vamdemon acted as a latent force directing Yukio's actions.
