In the rigidly class-stratified continent of Aurelia, a lowborn commoner girl named Elara unexpectedly receives an infant named Leo, entrusted to her by a lake fairy. This child of destiny, possessing the divine power of "upgrading all things," can turn scrap iron into real gold and wild grass into miracle medicine. However, this law-defying force not only draws the encirclement of gangs but also directly destroys the century-old economic lifeline monopolized by the old nobility, inviting endless pursuit.
When Elara discovers that every time Leo casts a spell to protect her, he falls into a near-death slumber, her "Mama Bear" instinct as a mother completely awakens. Knowing that retreat means certain death, she decides to become a Rakshasa of war. Using mythic-level resources, she befriends the Knight Commander, subjugates the Underground Black Market Queen, and adopts orphans Mia and Noah along the way—children shunned as monsters for their supernatural abilities. Facing assassins, evil dragons, and abyssal demons in desperate straits, Elara wields a starfire gun and awakens her Demon-Breaking Arm, crushing beneath her feet the old nobles and princes who sought to harm her child. In the end, she overthrows the rotten old order and builds an absolutely equal steel empire for all special children.
