Kuro Sharingan

The Kuro Sharingan (片立尺回　互廾人尺工几ム太几, Literally meaning: Black Pinwheel Eye, Meaning (Viz): Pitch Black Mirror Wheel Eye) is the Dōjutsu Kekkei Genkai of the Uchiha clan that appears selectively among its members. It is regarded as one of the "Three Great Dōjutsu", the others being the Byakugan and the Rinnegan. While its powers originated from Kaguya Ōtsutsuki's Rinne Sharingan, its independent form was first manifested by Sawada Uchiha.

The Sharingan grants the wielder two broad abilities: the "Heavenly Illumination : Blaze of The Sun" (Amaterasu : Taiyo no Hono) and the "Magatama Kamui" (Kamui no Magatama). Madara Uchiha noted that the Kuro Sharingan can only be used to its full potential when both techniques are unlocked.
