The blade known as Reidai Kitetsu is the long forgotten thirteenth Saijo O Wazamono, and the last known sword crafted by the legendary swordsmith Kitetsu, who created the three cursed blades Shodai Kitetsu, Nidai Kitetsu and Sandai Kitetsu. It is also known as 'Kitetsu Zero' and, more often than not, 'The Lost Kitetsu'. The blade is said to be possessed by the fire-demon Xaphan. Presently, it is wielded by The Conquering Hermit.
