After his death, former terrorist Alexander Dam gets a second chance at being reincarnated in a new fantasy world where magic is as important as science and technology. He is reborn as the son of one of the most powerful but retired villainess, Andrae Greyhart, under the name of Noah Greyhart. In this world, he discovers that he is not just at an advantage because of knowing his past life, but he is also a talented individual that many may call a prodigy.
Noah comes to learn that despite being a villainess's child, it would be normal for him to inherit his mother's abilities. Yet in his case, it's different: he doesn't have his mother's special abilities, but he has one special ability—one that can reshape the whole order of magic. From learning his mistakes from his past life, he vows to live a good and honest life because he didn't have the love of parents.
In this world, he learns the true meaning of friendship from his childhood best friend, a hard-headed princess named Anastasia Haven, in the capital city of the heart of Snowflake Kingdom. Apart from being a smart yet mischievous child, his life is somewhat full of adventure. From an alcohol- and gambling-loving mother to a teacher who is an old pervert, he couldn't complain.
As he grows up, Noah is forced to leave his friends, family, and old life behind after learning that if he doesn't take certain steps to harness and control his abilities, they won't just be a danger to everyone he loves, but will also risk costing him his life.
So he goes on a training adventure, and it doesn't end just there. As time and years pass, Noah makes a name for himself—not just as the child prodigy, but also as the most powerful figure in the seven kingdoms, remaining mysterious. When he returns home to live a normal childhood while attending school at the outstanding Academy of Magic Training of Evermore Magic Academy, he learns that the home he once loved has become a place of cults and rituals.
With his trusted familiar, Knight—a shape-shifting entity, but in the form of a black rare jaguar—he also comes to learn that the cults and rituals are just the tip of the iceberg compared to the brewing war between forgotten entities: the Astral and the Monarchs. Now he has to step in, as it happens that he is one of the major key pieces that are powerful enough to reshape the world into endless chaos. Now he has a choice to take: either he forsakes his peaceful life and takes part in this war, or he lets everything and everyone he cares for die.
