[[File:Koji.jpg|thumb|left|180px|Koji in the anime]]
Nagumo makes a brief appearance during the [[Battle City]] of the manga and the second series anime. After defeating a duelist, he is unhappy with the card he's won through the [[Ante Duel|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 English version he demands the two rarest cards in the duelist's deck.)
However [[Mokuba Kaiba|Mokuba]] appears and calls a foul. Koji insults Mokuba, but then [[Seto Kaiba]] appears. Seto appears and tells Koji off, saying that when when Koji speaks rudely to Mokuba, he dishonors Kaiba and the Battle City tournament, and also adds that he has "no patience for bullies". Kaiba then challenges him to a Duel with a briefcase of rare cards and "[[Obelisk the Tormentor]]". He allows Koji to use the cards from the briefcase in the Duel, but says he'll take them after he beats Koji. Kaiba easily defeats Koji with "Obelisk" and takes his [[Locator Card]]s.
