Kurokawa (クロカワ) is a character that has yet to formally appear in anything. She appears to be an older and slightly different version of Nataka. She seems to know a handful of Deep Sea Prisoner's other characters as shown in a MEMO image.
Kurokawa's appearance is mostly based on the monochrome pallete. She has fair human skin, dark gray eyes with black swirls in them, which is somewhat "lifeless" like Nataka. Her hair is long and black, with the sidebangs going past her shoulders, and is tied into a long braid with a white ribbon at the end.
She wears a monochrome stand up collar jacket, where the cuffs are white and has 4 black buttons at the sides. A white circle with a diagonal line through the circle can be seen on her left sleeve. She wears a gray scarf, and a black shirt(?) underneath. She also wears monochrome shorts with a gray belt over and black boots(?) which go past her knees with a white stripe at the top of the boots.
On her head, she wears a black ivy hat with a white brim, with a white ribbon visible at the left side. She also has a black piercing at her ears.
