Bount
Introduced in the anime, the Bounts are, like the Quincy, a clan of human beings with high spiritual energy and special powers. They were accidentally created by shinigami scientists looking for a way to create eternal life. Bounts consume the souls of human beings to survive; theoretically, a Bount could live forever by doing so. Although the Bounts have a strict rule to consume only the souls of the dead, the final group of Bounts has chosen to drain souls from living humans in order to become more powerful and destroy the shinigami world. Each Bount uses a "doll" in combat, a type of familiar possessing its own special abilities. Every doll is unique and is a manifestation of the user's power. If the doll is destroyed, its owner is destroyed as well.
