Emission

Emission (放出系, Hōshutsukei) is one of the six categories of Nen aura types.

Description
If a student changes the color of the water in the glass during their water divination, they are an Emitter (放出系, Hōshutsukei). An affinity for Emission means that a user is capable of controlling the deployment of their aura while separating it from their body. Aura usually decreases in intensity very quickly when it is separated from the source body, but strong Emitters can separate their aura from their body for long-periods of time and still be able to maintain it.

Some Emission abilities (such as Shachmono Tocino's) are commonly mistaken for Conjuration abilities. The two, however, are fundamentally different. Objects created by Emitters are created solely from aura and often require Manipulation skills to control.
