Yu-Gi-Oh! Duel 43: "Monster Fight!! (Part 1)"
Yu-Gi-Oh! Episode 60: "The Master of Magicians, Part 1"
|Video game debut|
Nagumo tries selling Alti and other Monster Fighter figures and guns he's collected for ¥30,000 each (about $278 US at the time). Dark Yugi comes into his store and fights Nagumo and his Wild Spider with Katsuya Jonouchi's monster, Killer Emaada. As the game was a Shadow Game, Nagumo's face was cracked in the first set, which went to Yugi; the Shadow Game dictated that the players, instead of the monsters, get damaged in the game. In the second set, Nagumo cheats by kicking Yugi in the side. Enraged, Dark Yugi raised the shadow mode to level three. When Nagumo tries to cheat again, his legs are held down by all of the monsters, including his own, and Nagumo saw, to his horror, the monster on his field was his own soul, composed of the Wild Spider's body, but his own face. Yugi then dealt the death blow, piercing the representation of Nagumo's soul, purging it of the darkness.
Nagumo makes a few brief appearances during the Battle City of the manga and the second series anime, apparently having recovered from his Shadow Game against Dark Yugi. After defeating a duelist, he is unhappy with the card he's won through the ante rule and demands that the loser give something of equal value to his card, "Hyozanryu" or else ¥100,000 (about $900 US at the time). (In the anime, he demands the two rarest cards in the duelist's Deck.)
However, Mokuba appears and calls a foul for changing the ante and wagering money. Koji insults Mokuba (calling him "Junior" in the anime), but then Seto Kaiba appears, shocking Koji, and tells Koji off, saying that when he speaks rudely to Mokuba, he dishonors Kaiba and the Battle City tournament. In the manga, Seto tears up the "Hyozanryu" card, saying Koji was going to lose it anyway. He challenges him to a Duel, anteing a briefcase of rare cards and "Obelisk the Tormentor". He allows Koji to use the cards from the briefcase in the Duel, to compensate for "Hyozanryu", but says he will take them after he beats Koji. Koji, overconfident at his newly empowered deck, suffered a devastating defeat as Kaiba unleashed "Obelisk", and takes his Puzzle Cards. Koji is left traumatized by Obelisk's overwhelming power, and ended up screaming in terror as he relived the image of the God crushing him. In the anime, Kaiba may have taken the "Hyozanryu," as per the ante rules, as he is later seen using it himself, although in the manga he stated he had 36 other cards just like it, and it may have been his own copy.
During the Battle City finals, he is seen observing the fight between Yugi and Kaiba from television screen in Domino City, along with other notable duelists that have been eliminated from the tournament.
Pyramid of LightEdit
During Yu-Gi-Oh! the Movie: Pyramid of Light, Koji was a bystander during Joey's duels in front of Domino High School at the beginning of the movie. His hair is brown in this appearance.
In the Yu-Gi-Oh! GX anime, he is listed in Austin O'Brien's database of Domino High School students as Kouji Nagumo. Later, Koji's name is listed listed among the disappearing residents of Domino City as Trueman sent them to the World of Darkness.
|Seto Kaiba||060||Lose (In Duel Monsters, the only card seen in his Deck was "Hyozanryu".)|
It is not known what sort of Deck he used in detail, yet a few cards were shown after his Duel against Seto Kaiba, though it remains ambiguous if the cards scattered over the pavement were part of his normal card set or exclusively taken from Kaiba's briefcase.
In the Dungeon Dice Monsters video game, his Dice Pool contained the following:
