Pluses are the benign ghosts in the Human World. They are the spirit of a person who has died. A chain, known as the Chain of Fate, protrudes from the chest and connects the soul to its living body. When this chain is severed, the soul can no longer return to its body and live. The soul can move about freely if the chain is broken, but this also causes the chain to slowly corrode. Normally, pluses are sent to Soul Society by Shinigami in a ritual called Konsō before this corrosion becomes significant. If the Chain of Fate is corroded entirely, the Plus will become a Hollow.
