Kagewaki Hitomi

 was the son of a daimyō. Naraku needed a temporary body to remain in the world, so he took advantage of Kagewaki's position and possessed him. Kagewaki's father was also possessed and then killed by Naraku while he was disguised as Kagewaki. Kagewaki's position also helped him with tricking Sango into believing that Inuyasha was responsible for the death of her clan.

Although Naraku changes bodies throughout the series, he keeps Kagewaki's face (and voice actor in anime).
