Description: Artificial souls are a type of soul mass-produced by the shinigami. Issued in pill form, they are used to force shinigami out of their gigai during protracted stays in the living world, and also to evict pluses that refuse to leave their bodies after death. They come with a pre-programmed personality that animates the host body until the owner returns. In addition to the mundane versions, a series of experimental souls authorized and created by shinigami researchers exists. Known as modified souls, these were meant to hunt hollows by possessing soulless human bodies and supercharging a particular aspect of them (for example, strength or speed). The shinigami decided to scrap the project due to the inhumanity of forcing dead bodies to fight, and ordered the destruction of all modified souls. Only one modified soul exists in the manga, but there are three more such characters in the anime.
