Magic Echo

Magic Echo (魔法の響き, Mahō no Hibiki) is a Caster Magic developed and practiced by Randall Flagg.

Description
A unique form of Magic that was developed and mastered by Randall ever since his days as a mage within Grimoire Heart. The principles of this magic are taken from the definition of an "echo", and applying that very principle to magical energy, which takes a variety of forms as a result. An echo, in the sense of a sound, is the reflection of sound, which arrives to the listener of the sound after a period of time; they are very common in areas such as the bottom of a well, by a building, or by the walls of an enclosed room. Encapsulating this concept within magic, Randall theorized that one could create a constant reflection of magical energy through condensing it an isolated region. The user can expand the volume of this isolated space as more magical energy is collected within it. Once this has completed, Randall can subsequently eradicate this isolated space and control this magical energy in a variety of ways; he uses these for offensive and defensive attacks of energy. Because it is raw magic that is being used, it cannot be manipulated by an external force as it is completely under Randall's dominion.
