I got the idea for this in my third block Enligh class today at school. The events take place during episode 111.

Dark Mist's P.O.V

I sit in the key alone and motionless, wishing that I had my precious blue gem beside me. But sadly, he was taken away from me... taken away before I could even try to save him. I watched as you pushed your real side out of the way, taking the pricing spear of darkness that was meant for Yuma. I watched as the darkness cuts right through that beautiful blue heart of yours. I ran to you to try and save you, but you told me to stay back. I stared at you with eyes full of fear. I begged you not to leave me, but you said that we'll be together again soon. I'll never forget the last words you said to me, "Goodbye, my flower of the night." I watched as you left me... all that I've ever care about, all that I've ever loved... was now gone. You were just as strong and kind as the Number that repented you. Just as Number 39 repented the hope for a winning duel, you repented the hope and love I had for... for you. Now that you're gone, I don't know if I'll ever get the chance to tell you how I really feel about you. I've always had a secret desire to be with you... to hold you in my arms, to tell you how special and beautiful you are to me. I still remember the days writing in my journal about how beautiful you were, how special you are to me. How I wanted to take your hand in marriage. If I could just have one wish, I would wish to hold you in my arms...
