It all started hundreds of years ago, back during a time when samurai still fought and traditional Japanese culture ran strong. It was in this era when a series of legendary blades where crafted by some of the finest sword smiths. Among them where blades such as the Hanjou Masamune and the Cursed Muramasas.
The Muramasa blade's, as their name implies, were cursed. The blades crafted by Muramasa were unbelievable deadly. Legend says that the man who crafted these blades prayed for them to be fierce blades of destruction. The quality of the blades stole the attention of gods, causing the gods to his wish. The blades where imbued with a blood-lust that could only be sated by battle. If the blood-lust was not sated, the wielder of the sword would be driven to murder or sometimes suicide.
It was not long before the Shogun of Japan, Tokugawa Ieyasu, made an edict condemning the swords after nearly all of his family was killed by the blades.
However, even after the edict was given, warriors who felt loyal to their sword secretly keep the weapons.
There was one man who was among these loyal sword wielders. A participant in the Battle of Sekigahara, he was left out of the history books. This man was known on the battle field as Kuro-Yasha, a name that means "Black Demon". He was known as this because of his brutality and ability to make his way through the enemy lines as if they were nothing. He was known as the only person that was able to control the blood lust of the blade that he held in his hands.
His real name was Tamazaki Hidetora. He was a simple person and off the battle field was kind and not at all threatening, though a tad bit strange or eccentric in personality. His jet black hair and red eyes made him threatening but inside, he was amiable and easy to get along with.
After the war ended, he raised his own family and left behind an unbelievable legacy for a time. His legendary sword was passed down through the ages, the legacy slowly fading into the shadows of history.
