Overview
Black Seiga (黒 青娥, Kuro Seiga) is a fan work of Seiga Kaku that started out as a illustration by Nagamin. The illustration has now been removed, but it was drawn by other artists.
Her hair and clothes are almost all black. Unlike the original design, she is wearing a Chinese dress.
Due to the design, she is often depicted in dark and sinister light.
Even though this is a fan work, there has been a official case with another character dressed in black. That being Black Cirno, a 2-player color palette swap used in Phantasmagoria of Flower View.
