Mokuren Nagai

Mokuren is a member of the Uruha and use to be partnered with Koganei. He was also a member of the Uruha (Maboroshi).

Mokuren is a ruthless and psychopathic killer. He intensely loves to kill women, and even refuses to do so with men, however, he later makes a special exception for Recca, who humiliates him in their "fight". After being so easily defeated, Mokuren swore revenge against Recca, and eventually comes to hate all the Hokage by association.

He will do whatever it takes to ensure that he comes out the winner, which includes blatantly lying and limitless cheating.
