A millennium ago, the Blue Moon Kingdom was engulfed in an endless war due to internal conflicts. On the verge of total destruction, the Kingdom was saved by the hands of a masked hero called the 'Red Man'.

As he took his last breath after getting shot by a gunman for attempting to save the kids, the principal of his school handed him a mask which gave him special powers. Kim, resurrected as the incarnation of insatiable, anger sets out to take revenge on the people who ruined his happy life. "I will bring my students back." Criminals beware. A teacher is coming after you to teach you regret and pain. (Source: Kakao Webtoon, translated)

And every day, I, in my free time, kept silent on my magic in my own way …. And as time passes, we know that aptitude magic is “creation magic”. I was delighted to think that creation magic is a hit. However, the surrounding adults were sad when they knew that it was creation magic … for some reason …. “Creativity magic is rare, but it’s incompetent magic.” Apparently, creation magic seems to be an incompetent magic that wastes the use of magic and can not make even simple things.

And, using the magic that has been trained so far, i will turn incompetent magic into useful magic!
