(Ahem! As for why it isn't Dragon Knight, I personally think Dragon Fang looks cooler. Of course, the setting will change, and the main and secondary Riders will change too.)
Mirrors are mysterious things, and countless legends surround them: they connect the worlds of yin and yang, reveal things from the underworld, and are linked to ghosts and monsters!
But in reality, another world exists inside mirrors. It is known as the Mirror World!
Mirror Beasts, ghosts... Knights driven by desire! A new battle has begun.
Faith and desire clash in a fight to the death! Only by fighting can you survive, until the cycle comes to a definitive end!
