Peacemaker

Peacemaker (平和維持, Heiwaiji) is a specialized, easy to use and compact magical weapon that works on the same principal as Face but on a smaller and individual scale. It is a militarized product that is sold by Horizon Industries.

Overview
After analyzing the ethernano-composition in one's body through it's quasi-spectral scanners and determining their exact vibrational frequency, the Peacemaker releases continuous waves of counter-vibration of varying intensity; depending on the ethernano composition and amount in one's body. This creates a personalized field inside which the victim is unable to use magic and if they actually try to use magic; not only it would put too much strain on their bodies but the counter vibrations would reach the resonating frequency, thus eliminating the ethernano in their body altogether and depowering them.

However, in order to prevent people from "misusing" this technology, retinal scanners that are configured to the retinal composition of their owners have been installed and every usage of this device sends an automatically generated notification to Horizon Industries; for them to monitor it's usage.

Trivia

 * A less destructive version of this device is known as the "Magic Dampener"; which is configured in such a way that it only creates an anti-magic field and never reaches the resonant frequency.
