Emission (放出Hōshutsu)

If a student changes the color of the water in the glass during their water divination, they are an Emitter. 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 decreased 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.

An application of this is the ability to throw giant balls of aura. Emission abilities are commonly mistaken for Conjuration abilities. The two, however, are fundamentally different. Objects created by Emitters are made of pure aura, believed to be invisible to normal people, and requires Manipulation skills to control.
