As extras on the Japanese DVD release, an interview with director Yoshiaki Kawajiri and brief interviews with voice actors Kenichi Suzumura (Kamui) and Junichi Suwabe (Fuuma) were included. The voice actor interview culminated with clips from a recorded performance of a special 'X' song not included in either the 'X - Yochou' episode or the later series. The song, called Yakusoku (Promise) was released on two separate limited CD singles (each featuring one of the actors). The director interview with Mr. Kawajiri ended up on the second American 'X' television series DVD, while neither the song footage or the CD singles were released in the United States. See more
I see a dream, and inside the dream, I can see the future. Two Divine Swords, and two "Kamuis..." I know these things will come. I am Kakyou, a Dragon of Heaven, one of the Seven Angels, a dreamseer who watches the future within dreams. Where did I come from? Why am I able to know the future? And what meaning is there in it? All these questions are meaningless to me now, for everything has already been lost long ago, with the person I cherished so much.
