Nen

Nen is a fictional energy manipulation concept from the anime "Hunter x Hunter," describing a person's ability to control and use their own life force or "aura." It allows individuals to enhance their physical and mental capabilities, create constructs, or even hide their aura from others. Think of it as a form of personal energy that can be developed and trained, much like a martial art, enabling various abilities depending on the user's skill and intent. Essentially, Nen transforms innate life energy into a versatile power source, balancing discipline and creativity.
