That does sound like a game shop, and Yuya's interested... But they probably won't have any duel monster cards there. At least 9S, looks happier. He's really missed out on a lot too, hasn't he?

"Fashion," that's the simplest response to 9S's question. "People like to look different and wear different stuff, so those shops make different styles. Like your clothes and mine."

"Since it's your first time in a mall, you should lead the way. Half the fun is just looking in all the stores to see what they have."
