Thermal Devil Slayer Magic

Thermal Devil Slayer Magic (寒暑の滅悪魔法, Kanshō no Metsuaku Mahō)

Trivia

 * This article was approved by Per, with her helping the author understand how this magic can work properly by explaining its properties. Like with its eclipse counterpart, this was something the author created as a test subject of sorts to see how it can work out.
 * This was created out of boredom, the author thinking it will have some use later on.
 * The kanji used to describe the word "thermal" (寒暑) actually means "summer and winter". This alludes to its status as a Dual Element, utilizing the powers of heat and cold simultaneously as a means of offense; it should be mentioned that thermal usually deals with such elements, making it all the more fitting.
