Magi-Neutral Fluid Injection (Nu Magic)
A serum of sorts developed by the Anrufe which, upon a single injection, alters the very DNA of the user ever-so-slightly in a safe manner so that the person emits AAM particles inside their own body, and with practice, around it to a certain radius. The more the user trains with this technique, the stronger the AAM inside them becomes.
