(YN) I decide to join the gang in a walking trip. As we are walking, Brock knocked off Yuma's necklace, and it landed on the ground. When it landed  a dark humanoid alien appeared out of nowhere. The alien to me looked a lot like Astral, and even Yuma agrees with me. The alien then says, "I am Dark Mist. I am going to duel you, Astral using your  good friend Yuma.  Oh and if you say no I'll..." He pauses as soon as he sees me. I push my way up front, and hiss, " If you want to duel somebody, duel me, otherwise..." Astral cuts me off, and the duel starts. 

(Timeskip to the end of the Duel)

[YN] So Astral absorbs this Dark Mist person, and Yuma is free. I decided to then walk home, and go to bed, thinking about D.M.

[Dark Mist] So I lost a duel with Astral, but there was a person watching that made me ME Dark Mist stop for a second. Her [h/c][h/l] hair looked super soft. Her [e/c] eyes glowed with the fires of determination. As I walked around inside the key, I was thinking about {her}, I pop out of the Emperor's Key, and beg Yuma to teach me about human culture. Needless to say he wasn't going to at first, but then I pulled a "lost puppy" look so he agreed. But, he said that if I did anything evil, I was going back into the key permanently. I "jump" in joy, and we start my "training".
