In the year 1600, at the fog-covered battlefield of Sekigahara, a fierce battle was waged by two exemplary swordsmen. One was Kyoushirou Mibu, a skilled and noble warrior in possession of the unique powers of the Mibu Clan. The other was the thousand-man slayer, with eyes and hair the color of blood, "Demon Eyes" Kyou. Their legendary clash was cut short when a meteor from the heavens fell down upon that battlefield, leaving both to vanish in its wake. (myanimelist.net)
