Buruburu

The Buruburu are Ghosts born of a person's fear after dying in a terrifying manner. They can then infect others with their fear, and this infection is known as the Ghost Sickness. The people they infect are usually people who have made a habit of terrorizing others. It is a spirit form that categorized and documented by the Japanese in the Edo period.  According to legend it attaches itself to its victim's spine and causes a chill to run down them, or in the worse case causes them to die of fright.
