Kuroi Ekazu

Burakku Ekazu is a deceased, but reincarnated shinobi once hailing from the original Jikanogakure. He was the second bearer of the Tetsuigan. Having been exiled to a great pyramid for his crimes against mankind. These crimes included raising the dead with ninjutsu, experimenting on other villagers, and many other heinous acts. Over the course of twenty years, he began anchoring some of his chakra to the pyramid. This chakra would begin to harness itself into a physical being after his death. Having taken five hundred years, the transformation was complete, and Burakku Ekazu was reincarnated just by the chakra he anchored to the pyramid. Breathing life once more, he wishes to raise an undead army to reign destruction upon the shinobi world.

Personality
In life, Burakku was always sadistic, sociopathic and shockingly calm, even when witnessing the deaths of anyone close to him. Lacking any empathy, he had a unique type of hatred that bordered on psychopathic. Even after his reincarnation, he still possesses these characteristics, but on an even more sadistic scale.

Appearance
When he was alive, Burakku had black hair that was long with spikes at the top. His eyes were yellow with vertical pupils. He had fair skin and was very tall and fit. After his reincarnation, his hair took on a silverish blue tone and his eyes changed dramatically, the sclera turning black and the irises changing from yellow to blue.

Ninjutsu
Burakku can use a vast array of Fire release and Yin release techniques. He can also put both of them to use, creating flames purely out of dark, spiritual energy. He can also trap opponents with the shadows by bringing his foe's shadow to life with Yin release, trapping his opponent and allowing him to go in for the kill. He created a unique form of the reincarnation technique, using sheer cold to keep his bodies intact and preserved. Once the time was right, all he has to do is give them a surge of dark energy, bringing them to life.

Taijutsu
Though rarely utilized, Burakku's Taijutsu techniques are powerful. He can combine his use of Yin release to deliver strikes that look like they wouldn't hit an opponent, but do due to creating waves of dark energy from the physical attack.

Nature Manipulation
Burakku can combine his Yin release and Fire release knowledge to create a wide array of different techniques, such as creating flames out of dark energy to throw as fireballs, or even envelop his foes around a ring of fire to prevent them from escaping.
