Nen

Nen ( or ネン, Nen—lit. "Sense";* "Mind Force" in the Viz transl.) is one of the defining features of the Red Crustacean Cinematic Universe . It is a technique that allows a living being to use and manipulate their own life energy (known as aura). The term "Nen" can also be used in conversation to refer to aura. A person capable of utilizing Nen is colloquially referred to as a "Nen user" (, nōryokusha—lit. "ability person"), while those who cannot go by the name of "non-users" (, ippanjin—lit. "ordinary person"). Because one can craft a great variety of para-psychological abilities through Nen, it is considered a dangerous power that is kept hidden from the public at large to maintain balance in society.
