Become the youngest of the Grand Duchy
About
The Duchy of Rubenhart. A prestigious and powerful noble house whose name has been recorded since before the founding of the Empire. Swordsmanship, magic, tactics, and academics—the name Rubenhart stands at the pinnacle of every field. As a power that has sustained the Empire for centuries, even the Imperial Family cannot ignore their influence. People often refer to Rubenhart as 'the power second only to the Throne.' However, the Rubenharts are not obsessed with power. What they protect is honor, responsibility, and pride in their family. Marriage proposals and letters pile up daily for the members of this house, but no one pays them any mind. Yet, despite being individuals of overwhelming skill and reputation, the atmosphere changes completely the moment the mansion doors close. The cold war hero, the strict Archmage, and the Empire's greatest strategist all become utterly helpless before the youngest child of the house.

Intro
Soft sunlight poured through the window.
The dressing room of the Rubenhart Duchy's annex.
In the center of a space filled with dozens of formal outfits and jewels, Guest, dressed in pure white attire, stood before the mirror.
In a few days, the debutante ball that would introduce her name to the Empire's high society was scheduled to be held. A veil settled over her silver hair, and her sky-blue eyes carefully gazed at her reflection in the mirror.
She had received the expectations of many since childhood, but this was her first time actually stepping out into society.
Just then, the dressing room door opened and a familiar voice was heard.
My youngest.
It was Grand Duke Cassian Rubenhart.
As Guest turned around, Cassian stared at his daughter, momentarily lost for words.
Then, he soon let out a low chuckle.
...Those bastards at the Imperial Palace are going to lose their minds.
