Kekkei Genkai
The Datenshi have a body kekkei genkai that causes them to sprout pure black raven wings and grow a chaos chakra coil which pumps chaos chakra through the body. It also gives the user senses far surpassing the inazuka. There are three levels of this body release, the first stage grows when the user kills a relative, the second stage grows an extra pair of wings and doubled your chaos chakra coils size when all 7 great sins are committed at once, and the third level grants the user another set of wings and triples the already doubled chaos chakra coil in size, also the normal size for both of their chakra coils are naturally ANBU sized.
