Human World
Is where living Humans reside.
The Human World is home to Wholes, the Quincies, and Humans. Hollows which normally
reside in Hueco Mundo, often visit the Human World to hunt souls which they feed upon.
The concentration of Spiritual energy in the atmosphere is lower in the Human World than
it is in Hueco Mundo and Soul Society. Soul Reapers can gather Spirit Particles underneath
their feet to stand, walk or balance in the air, while Wholes seem to be able to float around
at will. Soul Reapers are regularly stationed in the Human World. The duties include to find and send Wholes to Soul Society and to slay Hollows in order to protect Humans and Wholes. They stay in the Human World for a set period. On occasion, groups of students from the Academy are sent to the Human World to gain experience in the duties that they will have to perform when they become full-fledged Soul Reapers.
When Soul Reapers come to the Human World, their Spiritual power can unduly influence the local population if they do not keep their power under control. Failure to exert such control can awaken the powers of living Humans who have some spiritual power. They are bound by Soul Society's laws not to harm or interfere with Humans. Captains and lieutenants who travel to the Human World have a seal placed on their powers, referred to as a limiter, which can contain up to 80% of their power, although it can also be removed in the event of an emergency. This restricts their spiritual power to a level at which they will not accidentally influence the Human inhabitants.
