全てを奪われた元王子、仮面の軍師となり、暗躍無双して復讐を誓う

The Former Prince Who Lost Everything Vows to Reclaim His Kingdom and Avenge His Betrayal

In the Kingdom of Knights, a young prince named Grace, only ten years old, was born into a life of privilege and expectation. From an early age, he displayed remarkable intelligence and a natural talent for military strategy.

Having lost his mother to illness at a young age, Grace clung to the promise he had made to her—to ensure his younger sister’s happiness. With that goal in mind, he trained tirelessly in swordsmanship, aspiring to become a noble and formidable King of Knights, just like his father before him.

Grace was surrounded by those who adored him: Gilbert, his swordmaster and former captain of the Royal Guard; Aria, his devoted younger sister who idolized him; Lilliette, his bold and spirited fiancée; Alphonse, a timid yet kindhearted knight-in-training; and Hannah, a loyal maid who admired him deeply.

Not only the knights who served the crown but also the people of the capital firmly believed that Grace, with his extraordinary abilities and pure heart, was destined to be the next king.

However, in a cruel twist of fate, Grace was falsely accused of regicide—framed by his own cousin.

Through the schemes of Gaston, his treacherous relative, Grace was stripped of his royal title, his fiancée was taken from him, and he was cast into the depths of despair.

For two agonizing years, from the age of ten to twelve, he endured relentless torture in the dark confines of a prison cell, barely kept alive. As he suffered, his hatred for the cousin who had stolen everything from him grew stronger with each passing day.

Then, at twelve years old, Grace seized a fleeting chance and escaped.

Determined to reclaim his stolen kingdom, he understood that sheer strength was essential for his revenge. Concealing his true identity, he resolved to build his own order of knights—loyal warriors who would serve as his pawns in his quest for retribution.

Thus begins the tale of a fallen prince who travels the land, amassing power, honing his skills as a strategist, and plotting his ultimate vengeance—the story of a boy who will stop at nothing to reclaim his rightful throne.
