Events
Nagumo was unhappy with the card he had won through the ante rule, after one of his Duels. He demanded that his opponent give something of equal value to his card, "Hyozanryu" or ¥100,000 (about US$900 at the time). Mokuba Kaiba appeared and calls a foul for changing the ante and wagering money. Nagumo threatened Mokuba and told him not to mess with his rules. Seto Kaiba then arrived and warned Namugo that insulting Mokuba is insulting Kaiba Corporation. He proceeded to tear up the "Hyozanryu" card, saying Nagumo was going to lose it anyway. He challenged him to a Duel, anteing a briefcase of rare cards and "The God of the Obelisk". He allowed Nagumo to use the cards from the briefcase in the Duel, to compensate for "Hyozanryu", but said he would take them back after he won.

At some point in the Duel, Kaiba Summoned "The God of the Obelisk", easily defeating Nagumo, leaving him sit on the street, traumatized by the power of "Obelisk", with his cards scattered across the ground. The man who had lost to Nagumo, after witnessing the Duel with Kaiba, picked up the card he had wagered against Nagumo and tore it to pieces.
