Before the Battle City tournament, Yugi Muto and Joey Wheeler went here to collect their Duel Disks, along with Téa Gardner and Tristan Taylor. The three boys ogled over the cards on display at the window before entering. The merchant gave Yugi a Duel Disk, but Joey's rating was too low for him to get one and was initially not given one. However the merchant saw that Joey had "Red-Eyes Black Dragon", so he pretended that there was a mistake on the computer and upped his rating, allowing him to take a Duel Disk. After they left, the merchant phoned some Rare Hunters to go after Joey to win his "Red-Eyes".
In the shop's basement was where Pandora set up his special Duel arena, "Pandora's Room", against Dark Yugi, where the loser's legs will be sawed off by a buzzsaw. In the manga, Yugi rushed to the shop after realizing the shop owner was working with the Rare Hunters, and met Pandora instead. In the anime, Yugi was lured away into a tent and into a magic box that teleported him into the shop, all the while not figuring out the shop keeper was affiliated with the Rare Hunters.
