Artificial Souls

Artificial souls (義魂丸, gikongan), as the name suggests, are souls designed by Shinigami scientists to separate a Shinigami's spirit from a Gigai, should they be inhabiting one, or to evict stubborn spirits from their corpses if necessary. When ingested, it forces the soul out of the body and takes control of it, operating in a pre-programmed manner until removed by the Shinigami. It is commonly called Soul Candy, as the Shinigami Women's Association complained that the name gikongan wasn't cute and had it changed. To fit with the more informal name, Soul Candy is contained in PEZ-like dispensers with cartoon characters on top. The souls themselves apparently have personalities to match the cartoon character in question; for example, Chappy the Rabbit, is a hyperactive character and even speaks in a cutesy baby talk manner.

Modified Souls
Modified souls (改造魂魄, kaizō konpaku), more commonly referred to as Modsouls, are artificial souls designed to enhance regular human physiology, making them capable of battling Hollows equally. Because there are far more Hollows than Shinigami, a project labeled Spearhead was implemented in order to create a modified soul, in an attempt to even the gap. For example, one modsoul may be able to run many times faster than a regular human while another may be many times stronger than normal. The modsouls, just like regular artificial souls, are condensed into tiny, candy-like orbs. However, their originally intended purpose was to be placed into corpses to achieve their function as soldiers to combat Hollows. To fit with this purpose, they are also more independent than regular artificial souls.

The modsouls were exterminated after the experiment was halted due to ethical reasons, since they were intended to be used to reanimate human corpses to be used as weapons against Hollows.
