Eclipse Devil Slayer Magic

Eclipse Devil Slayer Magic (食の滅悪魔法, Shoku no Metsuaku Mahō) is one the more unique forms of Devil Slayer Magic seen to-date, its sole purpose is to combat the users of the Chaos Arts while maintaining its status of killing Demons and demonic entities. As if one couldn't tell by the name, it's a form of Slayer Magic — specifically Devil Slayer Magic, thus making it a Caster Magic by sheer default. Due to its main use of two elements for proper functioning, it's viewed as one of the dual-elements of its kind, making use of light and darkness — albeit from otherworldly sources, putting it on its own plane in terms of power and versatility.

It's current and only user is an immortal going by the name, Ars Goetia; apparently, he discovered the magic by sheer luck after a bad encounter with a Chaos Arts user. He perfected and masterfully wields it, seeing the variant as a means of destroying any and all Chaos Arts users he should so happen to encounter. Due to its overall nature that separates it from its brethren, he alternatively dubs the variation as the "Devil-Slaying Element of the Celestial Sphere" (滅悪因子の天界, Metsuaku Inshi no Tenkai).

Trivia

 * This was approved by Per.
 * Originally, this was going to be a form of the Chaos Arts; however, Per explained the incompatibility between Slayer Magic and said arts, thus the author had to opt for the standard Slayer Magic. Instead, he would use some aspects of the article in question, making this variant as powerful as any of the arts while having "certain" similarities. He also gave it the additional purpose of combating users of said magic, making it the only one of its kind that made counter two different enemies.


 * This magic was redux of a previous Slayer Magic the author created some time ago but was scrapped along with the character due to multiple complaints from the userbase on how it's "overpowered" and hard to understand at its core.
 * The overall designs for this magic is based off of the Meido Zangetsuha technique from the anime/manga series, Inuyasha.
 * The author found the name of this magic to be rather fitting, given that its power is dependent on certain locations, such as time of day or the location on where it's used — becoming stronger or weaker as a result. This is due to this variant of Devil Slayer Magic being rather..... unstable.
