Nuemaru is our Yakuza oyabun of a group called the Kaidan-kai. He rose to power primarily through his ability to 'leash' spirits with special talismans, and his saiko-komon, wakagashira and shateigashira are three examples of those spirits, all female. His first lieutenant is a Futakuchi-Onna with a mouth set in the back of her head, the leader of administrative duties is a Rokurokubi with an extendable neck, and his second lieutenant is a Yuki-Onna with a frozen touch of ice.

Nuemaru is represented by, and took his name from, the mythological creature- a Nue type of chimera with a tiger's body, a baboon's face, and a serpent for a tail.

As a side note.. I started this picture like... last year at some point and put it aside until just recently.
