The ultra card sitting upon the counter just glared at Yugi as soon as he picked it up, and it seems to blankly stare at the ceiling, while the arrogant, power-hungry Seto Kaiba first walked through the door of the store. Djinn didn't move from her spot, and the card just inanimatedly watched the scene before it. Before she knew it, the young man just up and left in a fit of anger with a frustrated huff. 

Peeking out from behind Yugi's figure, a shadow-like figure appeared on the flat of the wall, being just around the height of the young boy, but a little taller. The fully-black, smokey entity was obviously in the color of full smoke in what seemed to be an outline of an outfit and a high ponytail. 

"He just can't stand it", the female shadow pointed out aloud, with nobody seeming to hear or see her. "Seto Kaiba; jealous of your grandfather's collection", she whispered, unknowingly prompting the young boy to say it aloud. She didn't mean to use her whispering powers against him, and she didn't want to, but they tend to just come out on its own. When Yugi was about to speak, she shushed him. "No, no! Don't say that", she told him. Looking around at the people surrounding them. "Follow me. I'll explain", she whispered before beginning to lurk on the flat of the wall behind him.
