NEN

Nen is the ability to control one's own life energy or aura, which is constantly emitted from them whether they know it or not.

There are four basic Nen techniques:
Ten maintains the aura in the body, strengthening it for defense, Zetsu shuts the aura flow off, useful for concealing one's presence and relieving fatigue, Ren enables a user to produce more Nen, and Hatsu is a person's specific use of Nen.

Nen users are classified into six types based on their Hatsu abilities:
Enhancers strengthen and reinforce their natural physical abilities, Emitters project aura out of their bodies,Manipulators control objects or living things, Transmuters change the type or properties of their aura, Conjurers create objects out of their aura, and Specialists have unique abilities that do not fall into the previous categories.

A Nen user can enter into a Contract whereby pledging to follow certain Limitations, their abilities are strengthened in relation to how strict they are.
