A runaway shinobi of the Black Dragon Clan.
When Kazuki was born he was given the ability of "Kuroi_Ryu_Henshin" (Black Dragon Transformation)
It was said that the this bloodline was given to one ninja within the clan every century and if that ninja
was able to control the power he would be known as the Shinobi of Destiny.
As Kazuki grew he began to have trouble mastering the Black Dragon's powers.
When he transformed he would lose conscious and would blindly destroy anything insight.
Ninja's of his clan finally decided Kazuki would never be able to use Kuroi_Ryu_Henshin without losing
consciousness so they planned to kill him in his sleep at night.
What they did not know is that Raiga, Kazuki's younger brother and only family, cared for his brother more than
the safety of the village.
When it was time to kill Kazuki he already knew that the ninja were coming thanks to Raiga and fled the village.
Raiga stayed in the village that night fighting off any shinobi that were hunting down his brother giving Kazuki a head start on his life as a refugee.
In the end Kazuki escaped and his younger brother Raiga was executed for betraying the village.
Kazuki is now haunted with guilt of being a "scaredy cat" by letting his own little brother die because he did not want to.
Filled with shame everyday Kazuki feels like committing suicide because of what he has done and how he could of changed that if he learned to control the black dragon.
After many months of training and perseverance Kazuki is now able to control the Kuroi_Ryu_Henshin and travels the world as a missing nin
doing good deeds hoping to atone for the ultimate shame of leaving his younger brother to die and to become more courageous.
