The Cold-Hearted Royal Guard: My End Was Betrayal, My Beginning Is Your Protection

In her past life, Elmira was the ultimate shield—a top-tier bodyguard who never let her guard down. But even the strongest shield can be broken from behind. A single act of betrayal ended her career—and her life.Or so she thought.Opening her eyes in a filthy slum of a medieval world, she finds herself trapped in the frail body of a young girl named Maria. No weapons, no backup, and no strength. Just a gnawing hunger and a world that preys on the weak.But they are wrong about her. She is not just a helpless child.Deep inside... lies the mind of a veteran operative armed with modern knowledge. A sleeping beast waiting for the right moment to wake up.When danger inevitably comes knocking, the world will learn a terrifying lesson:You can strip a soldier of her armor, but you can never take away her lethality.From the dregs of the slums to the halls of the Royal Academy, this is the story of a girl who swore never to trust again—yet finds herself wielding her sword to protect once more. What to expect:Smart & Ruthless Female Lead: A protagonist who thinks before she acts and isn't afraid to get her hands dirty.Brains over Brawn: The MC has low mana capacity. She wins through strategy, modern martial arts (Judo/CQC), and physics—not by overpowering enemies.Psychological Depth: A realistic portrayal of trauma and trust issues. No instant "power of friendship."Magic Academy Arc: School life, but with high stakes, political schemes, and class discrimination.Weak-to-Strong: A steady progression where the MC earns her power through hard work and cleverness.Modern Knowledge: Using science to exploit magic systems.Cinematic Style: Long chapters (3k-5k words) with immersive descriptions. Perfect for readers who enjoyed:The tactical genius of "The World's Finest Assassin," the emotional depth of "Violet Evergarden,", the darkness of "Made In Abyss" and in the underdog triumphs of "The Irregular at Magic High School."If you are looking for a protagonist who uses science to defy magic and cold logic to survive betrayal, welcome to Maria’s world.
