Bone Demon

was a yōkai with the ability to rip the bones from a person's body out through their mouth by simply placing her hand in front of the victim's face.

History
She was first introduced in the form of a beautiful, young woman walking alone at night. She encountered a man who had just murdered someone for money; he became her next victim, ripping out his bones through his mouth. Inuyasha and his companions later found the victim's crumpled up skin and learned that there were more victims missing bones. Upon hearing the demon takes the form of a beautiful woman, Miroku immediately insisted on meeting her. He was joined only by Sango as Kagome remained behind with Inuyasha, who had become human.

The bone demon appeared again in front of Miroku and Sango, this time pulling behind her a cart loaded with bones, and took her next victims - three dog-like creatures who intended to attack her. Sango quickly struck the demon down with her Hiraikotsu, but they quickly realized she hadn't been defeated yet. Unfortunately, the demon now had her eyes set on Sango's Hiraikotsu.

Miroku and Sango followed the trail of bones left by the demon and arrived upon a beautiful young woman, who told them the demon had taken her form and that the mansion had been taken over by the bone demon. She wept, saying everyone else had been killed, including her parents. Suddenly, a wall came down and bones spilled out, revealing her demon father sitting on a pile of human bones. Sango threw her Hiraikotsu, but the demon caught it in his mouth. Miroku used his Kazaana to suck the weapon free, but he became weak. The young woman came to his aid, placing her hand in front of his face, but Miroku was able to block her with purification salt, revealing her as the true bone demon. She told them that her father had become ill and that she must collect bones for him.

Miroku and Sango became trapped, but were saved by Inuyasha, who used the Kaze no Kizu to eliminate the father's corpse, causing a hole to form in the roof. The sunlight of dawn caused the bone demon to dissolve and die.

Trivia

 * Her mortal weakness being sunlight was oddly similar to the weakness of a vampire; in most stories, vampires are reduced to ash by sunlight.
