Kitsune no u~isupu

The Kitsune no u~isupu is the Kekkei Genkai of the Mūn clan. The Kekkei Genkai allows the user to control the power of a domonic black fire,at the early stages of the jutsu the fire is formed into a ball at the hand but as it is mastered it is learned to be controlled more and more.There are 8 stages of the jutsu one being a ball of black fire around the hand and 8 being able to move the black fire at will.For example Skarlets brother Zin learned to move it like rain showering it on his enemy. This is one of the most feared jutsu,luckily it has stayed mostly in secret,When a child is born with pure white hair and white in the Mūn clan it is a sign they have the power to produce this demonic and powerfull Genkai Genkai,as the more they use the jutsu the darker there hair and eyes get until there are pure black.
