Djinn had absolutely no problem keeping her presence known for Yugi and, of course, Yami. Her obvious connection with darkness and shadows has allowed her to maneuver herself around in a variety of miraculous ways, sometimes to impress him; when he would make a move, his own projected shadow on the ground or wall would move differently, as if it had intelligence, and a life of its own. If he figured it out, Djinn merged herself into his own shadow, or shape-shifted on the spot. It was at that moment where she insisted to be simply called "Shadow". 

Of course, even while Djinn performed said-actions, it remained unnoticeable to Yugi's friends; she was just being playful, or showing signs of cleverness. Plus, when it suits her, she would sometimes merge herself with his friends' own shadows, particularly Joey's, and make her owner laugh. However, the spirit gladly stopped whenever he, or even Yami, would subtly ask her to leave them be. That was the way of fun she shared with him. It seems that Djinn has a mischievous side, a trait of a fiend-monster, aside from her polite mannerisms when they first met. 

Thankfully, she was patient with Yugi, and shifting herself back to her transparent form, Djinn gladly watched the event of a duel on the strange mechanism that Yugi told her about earlier. [i]So this would be the television?[/i], she thought, now knowing about the device before her. It was impressive, and the duel between Weevil Underwood and Rex Raptor. She didn't expect Underwood to win though; with a low-leveled monster, no dice. However, Djinn changed her perspective as soon as it came: he miraculously turned the tables, and defeated Rex with one clever move.

Noticing the transparent form of Yami next to her, she shared the spirit's curiosity when an unknown package came to both his host, and her owner. [i]From Industrial Illusions[/i], she heard them say, and this only made her have a mix of curiosity and worry. For once, Djinn shared the same nagging feeling that the spirit felt. "Don't you think that's a bit...odd, Yami?", she asked him when he appeared nearby.
