The Crown of Rutile Quartz (Manga)

Slaine spends his days living as a humble commoner in the quiet Kingdom of Hasenvalia—until the royal family is wiped out in a palace fire. In the aftermath, Slaine discovers a secret kept from him all his life: He’s the king’s illegitimate son and now the sole surviving heir to the throne! Thrust into power with no training and precious few allies, Slaine must navigate court politics, earn the trust of wary nobles, and learn how to rule a kingdom he never thought would be his. With his sharp-witted and fiercely loyal aide-de-camp Monica at his side, Slaine begins to grow into his role. But not everyone is pleased to see a commoner rising to the top. While some welcome the new king with cautious hope, others hide their true intentions behind polite smiles. As threats lurk in the shadows, young Slaine must rise to the challenge—or risk losing the crown before he ever gets to wear it.

Invasion is nigh! The Great Empire of Galed has launched a sudden strike against Hasenvalia. At the head of the enemy forces rides the fearsome Count Morgan Dubois, a general whose name is synonymous with pure brutality! Now, outnumbered three to one, Hasenvalia seems doomed to fall. But fate has placed its care in the hands of a young boy of humble origins—Crown Prince Slaine. Armed not with strength but with strategy, Slaine bets his kingdom’s survival on an unorthodox plan. Can Slaine rely on his wits to save his people and completely reshape the art of war along the way?
