Nurarihyon

Itsuki is a legendary demon who is said to have united a hundred demons in a single night. After that night, most demons started to think of Itsuki as the "King of Demons" or the "Leader of all Demons."

Human Form
Itsuki is male who looks like he is around eighteen years old. He has red eyes, short length black hair, and a well-toned body. Itsuki’s clothing is simple, comfortable, and easy to move in. Itsuki wears a tan under tunic under a tan Karate gi top. Occasionally he wears a long flowing black cloak that reaches his ankles. For pants he wears loose-fitting long tan pants. For shoes he usually wears black boots. 

Demon Form
When Itsuki enters his demon form he is depicted as a tall man with a gourd shaped head and glowing red eyes. The color of Itsuki's hair is shown to be a combination of white and black, the top being white while the bottom half being black.



Personality
Itsuki has a very mysterious demeanor. No one can figure out what goes on in his head. Itsuki can change from being relatively nice to sadistic at a drop of a hat. This unstable personality causes other people to stay away from him out of fear. One of the few things people know about Itsuki is that he is wise and smart. He knows his limits and he always seems to have a plan of retreat in his head.



To most demons, Itsuki is thought of as a king and a leader because of that very eventful night. As a result, Itsuki is shown having a more leader-like persona when he is around demons that are part of the  Hyakki Yagyō.

Not much is known about Itsuki before that fateful night when he untied a hundred demons. Some believe he was an average traveling demon while others believe he was part of an unknown organization.
