Personality
Koichi is a reserved boy with a kind heart who wants to do the right thing but is prone to burying his problems in his heart. Within him, however, is also a great potential for darkness, born from his resentment of his twin. Cherubimon uses this darkness to great effect, but Koichi overcomes this through his love for his brother.

As Duskmon, he is cold and aloof. He doesn't interact with the other members of his team, who can at the very least work together to a shared goal, and he sees only the value that they can bring. He is also single-minded loyal to Cherubimon, though much of that is due to Cherubimon's influence.

Description
Koichi is Koji Minamoto's twin brother and the elder of the twins. Their parents divorced when they were very young, and neither twin could remember the other. His mother never told him about his brother, and Koichi only learned about Koji when his grandmother told him on her deathbed. Koichi, feeling that his mother had enough to worry about, didn't tell her that he knew about his twin.

Koichi eventually managed to track down his brother, and after finding out where he lived, Koichi started to periodically watch Koji and his family. He yearned to meet his newfound brother but was never able to bring himself to interrupt the seemingly happy family. Over time, deep in his heart, Koichi began to grow bitter that their father had abandoned him and their mother, whom Koichi worried for due to the strain being a single parent.

On the same day that the rest of the enter the Digital World at Shibuya Station, Koichi decides to meet Koji and follows him to the train station, unknowingly crossing paths with Takuya Kanbara. After just missing the same elevator that Takuya himself only barely made, Koichi finds himself running to catch up with Koji, but he loses his footing and falls down a flight of stairs, collapsing as a result.

Koichi is taken to an isolated sector in the where he meets. Cherubimon, sensing the sadness and darkness residing in his heart, entices him to join his cause. He erases Koichi's memories and suppresses his personality by giving him the corrupted H Spirit of Darkness. As a result, Koichi becomes Duskmon, the Legendary Warrior of Darkness. Duskmon joins Cherubimon's corrupted Warriors as a distant, aloof ally, never really interacting with the others.

After loses his Beast Spirit to the DigiDestined, Duskmon is the only member of the evil Warriors to refrain from the assault on Seraphimon's Castle at the Forest Terminal. He stays out of most of the battle until a conversation with in which he calls into question Mercurymon's loyalty while Mercurymon calls him a coward for avoiding conflict. Duskmon, considering the DigiDestined an annoyance, decides that a battle would not be outside of his capabilities and proceeds to the Continent of Darkness. Duskmon arrives in time to see lose his Beast Spirit and, considering him a liability, dispatches him. Duskmon engages the DigiDestined twice in the Forest of the Continent of Darkness. The first time, he takes all of the DigiDestined's attacks without flinching, with the DigiDestined only fleeing after engulfs him in fire. The second time, he continues to be deeply disappointed with the DigiDestined's strength and attempts to strike down. takes the blow for him, reverting back to Koji in the process. As Agunimon screams Koji's name in anguish, the word resounds in Duskmon's consciousness and brings him pain, causing Duskmon to paint the entire area in darkness as he retreats to regroup.

Desiring answers to why Koji causes him pain, Duskmon enters 's Darkness Area and accosts Koji, sifting through his memories. Duskmon begins to doubt himself, making Cherubimon reinforce his hold over his Warrior. Duskmon and Koji clash, and though Duskmon comes out the winner, he is interrupted by 's before the finishing blow. Koji becomes, and the Warriors of Darkness and Light clash again, more evenly matched. With their souls bared in their blades, BeoWolfmon manages to get a glimpse of Duskmon's true form, right before their battle forces Sakkakumon to eject them from his body. Duskmon and BeoWolfmon proceed to have a running battle in the area around Sakkakumon, which BeoWolfmon eventually wins until Cherubimon personally intervenes. Duskmon continues to doubt himself, attempting to find out why BeoWolfmon invokes such emotions in him, so Cherubimon again cements his control over the Warrior of Darkness by reminding him of the day he came to the Digital World as well as the resentment involved. He then gives Duskmon the B Spirit of Darkness which enables him to become Velgemon. Velgemon sacrifices Duskmon's rational thought for immense power and an obsession with Koji's destruction. He nearly succeeds in his goal until intervenes through Koji's D-Tector, reviving Velgemon's suppressed memories. Velgemon once again flees to center himself.

Returning to his Duskmon form to regain his rationality, Duskmon again questions himself. This time, rather than wipe his memories, Cherubimon preys on Koichi's love for his mother to inflame his hatred. He gets into one final clash Koji, but the combined forces of both Koji and Takuya prove to be too much for even Velgemon's strength, and Koichi is defeated, the Spirit of Darkness taken from him. Now free of Cherubimon's influence, Koichi is wracked with guilt over his actions. He explains the events that brought him to the Digital World to the others and travels with them, though he remains distant and reticent. When Cherubimon attacks the they are riding on, Cherubimon tries to win Koichi back to his side by playing on his inner darkness once more. Koichi has moved beyond that, though, and flat out refuses. Cherubimon moves to kill his old servant, Koichi's conviction merges with the light from Koji's D-Tector to grant him the power to spirit evolve using the newly purified Spirits of Darkness. Becoming Loweemon and JagerLoweemon, he manages to defeat his old master, revealed to be just a shade of the true Digimon. Filled with a desire to atone, Koichi attempts to continue alone, only to be rebuffed and joined by the other, who want to see their journey to its conclusion.

The DigiDestined finally make it to the Rose Morning Star, where they sneak into Cherubimon's Castle and talk with the imprisoned Ophanimon, the one who chose the other DigiDestined, about the Digital World. They are interrupted by Cherubimon, who slowly defeats them and steals their Spirits. In an act of sacrifice, Ophanimon steals the Spirits back and upgrades Takuya's and Koji's D-Tectors for Unified Spirit Evolution, with which they win the first round against Cherubimon. Cherubimon's initial defeat releases an who seals Takuya and Koji, requiring the rest of them to fight. Koichi takes charge in this battle, leading to the defeat of the mass murder, and is fully acclimated into the team.

Cherubimon hasn't been totally defeated, however, and Koichi gives up his Spirits to allow Koji to unified spirit evolve. Their combined strength finally puts the dark angel down for good, but this doesn't fix everything that is wrong with the Digital World. The Legendary Warriors get another course in history from in the Tunnel of History only to be attacked by the   and. The Legendary Warriors lose spectacularly, getting blasted to the Blue Moon. The first to awaken, Koichi discovers the reduced gravity and flags down a passing patrol to take them to the Moon Base. The DigiDestined are then forced to claw their way back to the Digital World proper by breaking through the Electromagnetic Stream.

The DigiDestined continue to lose battle against the Royal Knights, with each defeat meaning that a section of the Digital World has been scanned for the purpose of reviving. All along the way, Koichi is haunted by the fact that even after the entire group is attacked with their fractal code showing, he remains more or less unscathed. At the battle at the Autumn Leaf Fair, Crusadermon reveals to Koichi the truth: he has no body in the Digital World, only a spirit. Koichi takes this to mean that his body in the Human World is dead. Koichi is deeply shaken by this revelation, only compounded by the fact that, at Ophanimon's Castle, Koji asks if they'll meet in the Human World. reveals to Koichi that he overheard what Crusadermon said, but Koichi swears him to secrecy. The DigiDestined eventually lose the castle itself to the Royal Knights, which leads to Lucemon's revival and the destruction of the Digital World. Disheartened by their utter failure, it takes seeing the Digi-Eggs and children they saved from the Village of Beginnings for the DigiDestined to find hope again; Koichi, in particular, bonds with a Poyomon. They manage to fully defeat the Royal Knights this time, only for Lucemon to sweep in and steal their fractal code to digivolve into his, destroying the very moons they stand on.

In the remnants of the world, Koichi attempts to tell Koji the truth, but they are interrupted by Lucemon opening a bridge to the Human World. They attempt to attack the fallen angel, but Koichi as Loweemon is knocked away in the struggle. This allows him to escape Lucemon's Ultimate Sacrifice attack even when it decimates the others. Knowing that the others could not take another attack, he takes the strike for himself. Bequeathing the Spirits of Darkness to Koji, Koichi's soul is scanned by Lucemon. His final act allows the others to become, which ultimately gives them the power to defeat Lucemon and save the Digital World.

On their way back, reveals that Koichi is not dead yet. The DigiDestined storm the operating room where Koichi is flat-lining. Through their tears and light, a miracle occurs as Koichi awakens, and the DigiDestined are completely united to celebrate their victory. In the aftermath of their journey, Koichi reunites Koji with their birth mother, happy that he no longer feels alone. Koichi makes the resolution to walk into the future with his friends at his side.



On the day of their birthday after their journey, Koichi directs an internal monologue to his twin on his way to meeting him. He remembers how he used to feel lonely in crowds and realizes that it was because Koji wasn't there. He tells Koji about how much he wanted to meet him before, and that though he still feels guilt about that his actions as Duskmon, Koji's smile is like absolution to him. He tells Koji how safe he makes him feel, deciding that he would ultimately thank Koji for being born with him.
