I don't know whi Kyo has an outfit^.^;; It mai be nothing, but it's on the same page as Yuki, Momiji and Hatori's cerimonial stuffs in the character book. Aniwho, I'm attaching an image of it, not from the character book but the same outfit. I think this image is from a random card set or something.
Things need not have happened to be true. Tales and dreams are the shadow-truths that will endure when mere facts are dust and ashes, and forgot.
