Kyo

The Demon Sword Kyo (keeyoh) is the legendary artifact of Tohka Natashi, obtained by touching the Demon sword displayed in her family's living room that she was never supposed to touch. Kyo was passed on through the Natashi family line, which is why it chose her as its wielder. She discovers she has the legendary artifact during the Attack on Kyoto when she ends up going face-to-face with an Angel soldier.

=Appearance= Kyo is a black, one-handed steel sword. The hilt looks like a dumbbell with a black ball at the end and a black circle in the center. The blade itself is also black, but appears endless like the night sky. Even has some stars on it.

=Powers= By slicing through its opponent, without damaging them, Kyo sends its user and the opponent to a separate dimension to duke it out.
