Fan:Kouichi Kimura

This article details the relationships between Koichi Kimura and his fellow DigiDestined of Digimon Frontier.

Koji Minamoto
Upon finding out from his grandmother that Koji existed, Kouichi proceeded to somewhat stalk him, as he was very curious as to what kind of person Koji was. But when Koji was chosen to go to the Digital World and Kouichi was left behind, Kouichi began to feel resentment and jealousy, which caused Cherubimon to take him in and transform him into Duskmon.

As Duskmon, there are some significant traits of his fixation that remain. He starts to regain himself when Takuya yells Koji's name, and eventually regains his memories back. However, his anger towards Koji is still manipulated by Cherubimon and it takes a straight-on confrontation from Koji to get Kouichi back to normal.

Once again normal, and now a member of the DigiDestined, Kouichi continues to pursue his goal of finding more about Koji's personality, eventually developing a protective and caring side towards him. This culminates when Kouichi sacrifices himself in the interests of his brother.

Kouichi survives by virtue of not truly being in the Digital World, and eventually he goes to take Koji to see his mother.
