Watakushi, Makemasen node. Seiryaku Kekkon wa Reijou no Tashinami

The region of Parsa in the state of Karana is jointly governed by two great houses: the Fullranet family, masters of magical power, and the Romano family, unrivaled in martial might. Each house has a daughter whose breathtaking beauty and extraordinary abilities mark her as the future countess.

Annamaria Fullranet, known as "The Black-Magic Lady."

Rosaria Romano, known as "The Silver-Knight Lady."

Though childhood friends, a trivial incident in their youth shattered their bond, turning them into sworn rivals who clash at every turn.

Then, Duke Jeremiah arrives in Karana. A royal with prodigious magic, he had served as a general in the capital's Sorcerous Kingdom Army—only to abruptly resign and relocate to Karana. Rumors swirl: He's here to find a bride.

"Marry him, and I'll rise as duchess, lifting Parsa to new heights!" both ladies think.

As the two reignite their feud, Jeremiah reveals a secret.

"My source of magic—the gem Smeraldo—has been stolen. I can no longer cast spells. Whoever recovers Smeraldo... I will marry."

And so begins the coldly calculating courtship battle between two noble daughters—purely for power, prestige, and Parsa's future!?
