Name: Dark chakra engulfing abyss
Rank: S
Type: Ninjutsu
Element: Dark (usable in my kekkei genkai)
Description: As Hiei uses his kekki genkai, it grants him the ability to use dark chakra. This is the final jutsu Hiei masters right before he leaves the village for his own reasons. Hiei uses this to kill several leaf villages who try to stop him.
Dark chakra engulfing abyss surrounds a large area in darkness, favoring Hiei because he is able to see extremely well in dakrness and favors his kekkei genkai because it brings the realm of the dark chakra dragon to him disabling a bodily sacrifice to be made upon using this jutsu and also reducing the chakra consumptoin in half.
