Shadow Manipulation

Name:Shadow Manipulation
Type:Ninjutsu/genjutsu can be used with this also.
Rank:C-S
History:This will occur very very Rarely, when two DNA genes clash, and when the clash it becomes unstable, they start to turn black, creating their shadow manipulation.
Abilities:They are able to manipulate shadows completely shaping them, hiding within them, pretty much making them come alive and control. When shaping them the can have some sort of shadow beast come out of the shadow and attack the user, it is a bloodline summon. They can also have tendrils (tentecales, shadow sewing) at will, whenever they feel, this is the only thing they can do without a jutsu. They can also use shadows for doing other things, like carry things, daily things.
Drawbacks:They have an obession with killing, which is hard to keep at bay, and when they loose control they will try to kill every living thing around them even teammates. They are aware of what is happening, they can't control their body only what they say and think.
Extra Notes:
