Zenji is a bald stocky man with a mustache and soul patch. He is usually seen wearing a black suit with a red shirt and yellow tie. He also wears a small pair of sunglasses.
Zenji is a pretentious individual who despises Light Nostrade for his quick rise through the ranks of the mob and the unconventional way he did so, which Light interprets as envy. He becomes irritated very easily, and did not hesitate to punch Light in front of multiple witnesses and to yell at Kurapika while the latter was pointing a knife at his throat. He is also vindictive, which he showed by outbidding Kurapika and later attempting to kill him, although Kurapika's Ren made him desist.
