Nen Type

Nen

Nen is energy that produced by any living beings, but it only leak out of body slowly. It also that keep us alive, loosing Nen would be fatal. The pore or points on body where Nen flows out called Aura nodes.
There are basic technique for controlling Nen:

Ten
Nen user has to learn how to open and close Aura Nodes so they can control Nen flows. It can be done by meditate, but it need quite long time, or received someone Nen to force Aura Nodes to open. This way is faster, but also risky. Once it opened, Nen will bursting out fast and if the user can not control it, they can't be exhausted or even die. When Nen user able to control the flow of aura surround the body, they can defend against phisycal or mental attack from another Nen user.

Zetsu
Different with Ten, Zetsu completely close Aura Nodes so it stop leaking out of the body. With closing Aura Nodes, Nen User able to tracking other Nen user, and it also prevent another Nen User from noticing them. Since it close Aura Nodes, their body will be defenseless and can easly get damage by small amount of Nen attack.

Ren
Ren is an advance of using Ten. By increasing the amount of aura around them without losing it, it can increase the user's physical strength and provides a large pool of aura for any advanced technique they want to use.

Hatsu
Hatsu is the release of user aura and it a special and unique ability for each user. Every user has their own hatsu character, and the cannot copy another user ability.
