Nikolai has white layered, sharp hair swept to the left side of his face. However, as short as it seems, he also has a long braid of hair that often rests on his right shoulder. A scar is slit vertically down his left eye. Compared to his left eye, his right eye appears vacant, bearing no highlights in it. He wears a mostly black jacket, the right side being solid black, black-and-white striped trousers, a shirt with a ruffled, round collar akin to a loose elaborate turtleneck, and dark gloves.
