Artyuuru is a boy who reincarnated into a fantasy world only to discover he was born without any magical attributes, rendering him completely unable to use magic. His deficiency leads his own noble family, the Marquis, to disown him, and he is forced to move with his mother Martine to a remote border village. Refusing to waste his second chance, he decides to pursue alchemy, a craft that requires no elemental affinity. Drawing on the knowledge of his past life, he begins experimenting alone. Through painstaking research, he learns to manipulate his mana into a visible state called Rudo, allowing him to draw alchemical arrays by hand without expensive tools. This breakthrough lets him create practical goods such as amber jewelry and corrective eyeglasses, gradually improving daily life in the village. His creations attract attention, both from neighbors who need help and from outside parties who see profit in his innovations. As his reputation grows, Altyuuru launches a glassmaking enterprise, navigating the challenges of hiring workers and setting up a proper workshop. Tension escalates when a villager disappears, revealing that a band of orcs is drawing near the settlement. Combining his knowledge of chemistry, metallurgy, and strategy with the unique properties of this world’s alchemy, Artyuuru works to defend his home and continue building a life defined by ingenuity rather than raw magical power.
