Human

A Human (人間, Ningen) is a living being. Most people who live in the Human World are Humans. A Human's body, like everything else in the Human World, is constructed out of Kishi (器子, Holdlets) and contains a Soul, bound to it by the Chain of Fate.

Overview
Most of Humans are do not know of the dangers they are exposed to from Hollows and other spirit beings. Hollows make their former loved ones into their first victims before they begin preying on Plus Souls, being the primary reason for attacks on humans. A severe enough attack from a Hollow, or a Shinigami, on a living human would result in bodily harm but also the the removal of the Human's Soul from the body. The damage can be easily repaired through Kidō if the Chain of Fate wasn't broken. Shinigami are forbidden from attacking Humans, unless ordered to. They generally ignore Humans, but a part of their duties is protecting a Human in jeopardy from Hollows. Some Shinigami view Humans as inferior, despite the fact that the majority of Souls, including most Shinigami, are of Human origins.

High Spec Humans
A very small amount of Humans develops high amounts of Reiryoku; they are known as "High-Spec" Humans. These Humans are able to see and interact with Reishi made objects, such as Souls and hollows, to varying degrees and for various reasons.

In even rarer cases High-Spec Humans will develop powers, either spontaneously or due to an intervention, which will allow them not only to interact with Souls but also to defend themselves and others against spiritual dangers such as Hollows and other parasitic spirits.

Quincy
The Quincy (滅却師 (クインシー), Kuinshī; lit. "Monk of Destruction") are spiritually aware Human warriors. They use their ability to absorb and manipulate Reiryoku to create bows and arrows from spiritual energy. These arrows and their related techniques are dangerous to spiritual beings.

Fullbring
Fullbring is a special ability which certain Humans are born with, in which they can manipulate the "soul" of matter for a variety of effects. Fullbringers each have a parent who was attacked by a Hollow before they were born. Traces of the Hollows' powers remained in their mothers' bodies, which were then passed onto them when they were born. Thus, the powers resemble those of Hollows more than they resemble those of Shinigami's.

Shinigami Representative
Also known as Substitute Shinigami, as Humans who have managed to gain the powers of a Shinigami, normaly fighting for the same goals as any regular Shinigami.

This form of Shinigami are still considered Human, due to the fact they are human in their Physical body and a Shinigami in spiritual body. With their abilitys, they have an easier time combating hollows then any normal human. They are also more durable and stronger then a normal human.
