In his previous life, Isaac was anything but hardworking. Convinced that he simply lacked the talent needed to accomplish anything meaningful, he gave up on trying and eventually became the sort of bitter shut-in who mocked people who actually put effort into improving themselves. Only as his life comes to an end does he finally realize how badly he wasted it. If he could have another chance, he wishes, he would stop making excuses and become someone willing to work for the things he wants. Then he opens his eyes as a baby in another world. Reborn as Isaac, the eldest son of the Redscroll family, a humble family of alchemists living in a remote village, he decides that he absolutely will not waste his second chance. He begins studying language while still an infant, trains his magical power from an early age, and eagerly learns the fundamentals of alchemy and crafting from his family. For the first time, Isaac discovers the satisfaction of watching something he couldn't do yesterday become something he can do today. Before long, he genuinely falls in love with working hard. Then Isaac's eyes awaken to a mysterious ability that allows him to perceive magical power itself. By carefully observing and analyzing what he sees, he begins applying his discoveries to magic and alchemy, steadily producing results that leave the adults around him astonished. Isaac assumes this is simply what happens when someone works hard enough. There's just one problem: he's wrong. The boy who spent his previous life convinced that he had no talent has been reborn with potentially the greatest magical aptitude in history. And as effort and extraordinary natural ability begin reinforcing one another, Isaac unknowingly starts down the path toward becoming an alchemist unlike anything the world has ever seen.

A reincarnation fantasy about a former failure learning to love hard work, without realizing that his combination of relentless effort and monstrous talent is turning him into one of the most exceptional magicians in the world.
