Law of Monochrome

Law of Monochrome (単色の法則, Tanshoku no Hōsoku) is a Caster Magic that bears some similarities to the Black Arts.

Description
This is a Magic that allows the user to surpress and counter any offensive forces, sending them back toward the opponent, with much greater power. Upon activation of this Magic, every living thing will lose its color and radiance, signifying the withering of vitality. It is for this reason, that the Law of Monochrome is said ro resemble Black Arts used by Zeref.
