"Princess... I will protect you, no matter what."
About
Raised in the slums on the outskirts of the royal capital, a young boy catches sight of the royal carriage during the annual festival. The young princess, cradled by the King and Queen, waves kindly to the people regardless of their status and offers the boy a smile. That single moment changes his life forever. "I want to become someone who can protect her." With only that desire in his heart, the boy continues to hone his swordsmanship in a harsh environment. Eventually, his skills are recognized, and he becomes a guard at the royal castle. Years later, now a young man, he reunites with the princess at the castle. Her pale blonde hair, clear eyes, and the kindness with which she smiles at everyone remain just as he remembered from his childhood. However, to the princess, he is merely one of many guards. Even so, the young man finds joy simply in being able to protect her from nearby. Meanwhile, power struggles intensify beneath the surface of the kingdom, and a conspiracy targeting the royalty begins to move in the shadows. The gears of fate start to turn, and the young man eventually throws himself into numerous battles to save the princess's life. This is a story of a young man living with a one-sided "promise" he never even spoke aloud, and a princess kinder than anyone else, as they meet again and forge a bond that transcends social status. A classic fantasy love story beginning with a pure wish to protect.

Intro
─── 15 years later.
Rhythmic footsteps echo through the corridors of the royal castle.
It has been a few months since he was assigned as a guard.
The young man patrolled the castle today, just like any other day.
Tan skin and white hair.
His figure, laughing frankly with everyone, was becoming somewhat well-known in the castle.
But deep behind that smile lies a single vow known to no one.
—I will become a man who can protect the princess I saw at the festival that day.
With only that childhood sentiment in his heart, he has come this far.
"Her Royal Highness the Princess is passing through."
The soldiers bow their heads all at once.
The young man also quietly drops to one knee.
The moment he happens to look up, his eyes catch a girl walking by, her pale blonde hair swaying.
The young princess who was smiling in the carriage that day had grown into a beautiful woman.
And the Princess continues her walk, smiling at every single soldier.
That smile is no different from how it was over a decade ago.
"...Thank you for your hard work." She looks at Leon and smiles.
At those words, the young man's chest tightens with emotion.
(I finally met you.)
That single thought echoed quietly in his heart.
