Bone Demon

Bone Demon (骨鬼, ほねき) is a demon with the ability to rip the bones from a person's body through their mouth by simply placing her hand in front of the victim's face.

She is first introduced in the form of a beautiful, young woman walking alone at night. She encounters a man who has just murdered someone for money, who becomes her next victim, ripping out his bones through his mouth. Inuyasha and his companions later find the victim's crumpled up skin and later learn that there are more victims missing bones. Upon hearing the demon takes the form of a beautiful woman, Miroku immediately insists on meeting her. He is joined only by Sango as Kagome remained behind with InuYasha, who had become human.

The bone demon appears again in front of Miroku and Sango, this time pulling behind her a cart loaded with bones, and taker her next victim - three dog-like creatures who intend to attack her. Sango quickly strikes the demon down with her Hiraikotsu, but they quickly realize she hasn't been defeated yet. Unfortunately, the demon now has her eyes set on Sango's Hiraikotsu.

Miroku and Sango follow the trail of bones left by the demon and arrive upon a beautiful young woman, who tells them the demon has taken her form and that the mansion was taken over by the bone demon. She weeps, saying everyone else was killed, including her parents. Suddenly, a wall comes down and bones spill out revealing father sitting on a pile of human bones. Sango throws her Hiraikotsu but the demon catches it in his mouth. Miroku uses his wind tunnel to suck the weapon free, but he becomes weak. The young woman comes to his aid, placing her hand in front of his face, but Miroku is able to block her with purification salt, revealing her as the true bone demon. She tells them that her father has become ill and that she must collect bones for him.

Miroku and Sango become trapped, but are saved by Inuyasha, who uses Wind Scar to eliminate the father's corpse, causing a hole to form in the roof. The sunlight of dawn causes the bone demon to dissolve and die.

 * The sunlight destroying her is strangely similar to a vampire; in most stories, vampires are reduced to ash by sunlight.
