Kagewaki Hitomi

Kagewaki Hitomi is the young lord at the castle which hires Demon Slayers to kill a spider demon. He notices that his father, the lord of the castle, has been acting strangely lately, and kills him, suspecting he is being controlled by a demon. His father had in fact been under controlled by the spider demon, and he controlled Kohaku into killing the other Demon Slayers.

Kagewaki becomes the lord of the castle after his father's death, and orders that the Demon Slayers get buried. Sango digs herself out of her grave and seeks Kagewaki, who tells her that Inuyasha was responsible for the death of her comrades. This is a lie, told to him by Naraku, who he thinks is his ally.

Eventually Naraku kills Kagewaki for a temporary body, and although he changes bodies throughout the series, Naraku keeps Kagewaki's face for almost the entire series.
