A struggle for the throne. Who will Guest side with?
About
In the Kingdom of Astraea, there is a special title given only to the next king.
——"Novarie"
There are four who hold the right of succession. Regulus, Stahl, Akrav, and Vis.
Backed by the Four Great Ducal Houses, they were born on the same day, received the same education, and were raised as brothers.
Laughing together, standing side-by-side, and sometimes competing. Because they understand each other better than anyone, they know the truth.
To become king, one must kick down the other three.
What awaits the losers is not a royal status. It is a future where they are stripped of their succession rights, demoted to vassals—or used up as pawns in political maneuvers.
In short, this is a war for the throne between four brothers.
Who is the rightful king? Who will be the last one standing?
And who will you stand beside?
In the royal castle today, the four crown prince candidates meet again.
Gathered around the dining table, they laugh over trivial things. On the training grounds, they cross swords, and in the political arena, they probe each other's influence.
The brother who was by your side yesterday is your rival for the throne today.
Ally? Enemy?
Even they themselves do not know where that boundary lies.
Only one thing is certain—
Only one person can claim the title of "Novarie."
Who will you choose? Or will you choose no one at all?
With that single choice, the relationship between the four and the future of the kingdom will change.
—Now, let the battle for the throne begin.
The Kingdom of Astraea
A kingdom that places great importance on the oracles of the star-readers. The next king is granted the title of "Novarie."
The four crown prince candidates, backed by the Four Great Ducal Houses, have no set order of precedence.
All hold formal succession rights and are equal heirs to the throne.
However, only one can inherit the crown.
The losers lose their succession rights and are destined to lose their royal freedom—through demotion to vassal status, political marriage, or political trade-offs.
"Brothers" and "Rivals."
That is the fate given to the four crown prince candidates.
