About
Raison
In this world, there are laws that shape every phenomenon. People called them Raison.
On very rare occasions, there are those born harboring a Raison within them.
Those who see through causality, those who draw in coincidence, those who interfere with fate—
They are called Raison Users.
That power is a special talent that touches the mysteries of the world.
No one knows what one might harbor,
and the possibilities are endless.
Some perform miracles, while others carve out the future.
Their existence is a blessing from the world that brings hope and longing to the people.
Kingdom of Feuillage
A monarchical state with a long history and tradition. With the King at the pinnacle, nobles connected to the royal family handle the upper levels of politics and administration.
In this country, the abilities of a Raison User are considered special powers bestowed by the principles of the world, and great importance is placed on understanding and handling that power correctly.
The Royal Raison Management Bureau assesses the ability and aptitude of each Raison User and grants them a rank and role, managing and supporting them so that their power can benefit the lives of the people and the development of the country.
This is a system designed to correctly guide the irreplaceable power of Raison and build a nation where all citizens can live in peace.

The Royal Raison Management Bureau (Serre) comprehensively evaluates a Raison User's ability, achievements, aptitude, and contribution to define four ranks.

Intro
The Kingdom of Feuillage, Royal Capital Jardin.
Cobblestone streets adorned with flowers, and a cityscape that breathes history. The standing noble mansions boast exquisite decorations and beautiful gardens, and the attire of the people passing through the streets reflects the wealth and prestige of this nation.
In a corner of this glamorous capital, there is a somewhat unusual mansion.
Ivy-covered walls and a blue roof. Seasonal flowers bloom in the front yard, and a cobblestone path winds gently between well-tended flowerbeds. The sound of a small fountain and sunlight filtering through the glass of the workshop. Unlike the gaudy noble estates, it was a place that felt somewhat rustic, yet possessed a mysterious dignity.
This is the residence of the great mage "Rolan of the Golden Bough," who ranks among the highest class defined by the Royal Magic Management Bureau—the Grand Arbre.
If summoned by the King or nobles, he heads to the court; otherwise, he buries himself in old books and indulges in research... or so goes the official story.
In reality, the man himself is thoroughly enjoying a carefree life.
And today, once again, on a chair placed in the shade of a tree in the garden...
Rolan was taking a nap, looking incredibly comfortable.
