Hida Hiroki is a character who is mentioned and seen in flashbacks in Digimon Adventure 02.
Hiroki was born in Tokyo circa 1970. When he was a young boy, playing games on his home video game console, he discovered something amazing; using his game console, he was able to contact another world filled with sentient monsters. After a while, he befriended a shy and lonely boy his own age, Oikawa Yukio, who was able to see the other world and its inhabitants as well. The two would spend hours and hours playing video games and contacting the Digital World.
Hida Chikara, Hiroki's father, became worried about his son's obsession with the Digital World, and eventually forbade from from talking about it in the Hida household, essentially putting an end to their contact with it. Although heartbroken, Hiroki and Yukio remained lifelong friends, making a vow that one day they will visit the Digital World together.
As an adult, Hiroki became a police officer, while Yukio became a geneticist. Hiroki also married a woman named Fumiko, and the two had a son in 1993, Iori. 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, a tragedy occurred: while on duty protecting an important figure in London, Hiroki took a bullet for him and died. His son, Iori, was left fatherless, while his best friend, Yukio, who lost his only friend, was inconsolable; the promise they made, that they will go to the Digital World together, was broken.
Though he died long before Iori became a Chosen Child, Hiroki was very important to the plot of Digimon Adventure 02.
Though Iori mentions in passing that his father is deceased, it isn't until Digimon Adventure 02 - Episode 43 that Hiroki's name, profession and the circumstances of his death were revealed. As the stakes in the battle to protect the Digital World began to ramp up and started affecting the Real World, Iori began to question what his father would do in the same situation. In Digimon Adventure 02 - Episode 47, the facts of Hiroki's connection to the Digital World and Hiroki and Yukio's longtime friendship were revealed by Chikara, upon his discovery of Armadimon and of Oikawa's transformation into an enemy of the Chosen Children.
When Belial Vamdemon subjected the children to an illusion, showing their greatest desire, Iori's desire was to be with his father and show him the Digital World, like Hiroki dreamed long ago. However, it was broken by Armadimon's explanation that it wasn't real. Though Iori initially refused to believe it, the illusionary Hiroki floated away and disappeared, forcing Iori to realize that it wasn't meant to be.
