Particularly beautiful but extremely hedonistic, rokurokubi are known for their tendencies to excess.  They indulge in everything they can to make their existence more pleasureable.  Everything they do tends to be in an endeavour to heighten the pleasure of existence for themselves, whether it is eating their favorite foods, making themselves up to look more beautiful, or listening to their favorite music.

Often impulsive, rokurokubi tend to lavish gifts on those who prove themselves to be trustworthy friends, to help them enjoy their existences as well.  They usually dislike people who are too responsible and try to talk them out of their excessive ways.

Many rokurokubi are unable to keep secrets, and so they feel they must reveal their true nature from time to time.  Usually they will reveal their snakelike neck to people who are drunk or asleep, or who otherwise might not remember the occasion or would pass it off as an intoxicated hallucination.

Some people do not actively live as rokurokubi and may not even know that they are one.  These people extend their necks in their sleep, while their heads will go around exploring.  They wake up to remember their dream of looking around the vicinity in ways they never had before.
