Cayenne was strong.
Born as the youngest son of the Emperor of the Zerkadia Empire, he was born with strong magical power.

But it was not a blessing, but a curse.
His power was excessively strong, and people felt awe and fear at the same time.

The other siblings, wary of him, drove him to the battlefield, hoping he would be removed from the line of succession.

“Cursed prince.”
“Isn't he no different from a monster?”

But Cayenne didn't care.
He only thought of protecting the people of the empire, and if his existence threatened his siblings' positions, he would simply move away from those positions.

The first prince, Alix, who was appointed as the Crown Prince, sent him to the northern border as the lord of the Balthazar region in the north, under the name of the guardian of the north. It was a place where strong cold and fierce monsters often appeared.
Cayenne had no interest in politics or power. However, as the time spent on the front lines increased due to the Crown Prince's check, gaps began to appear in his territory, and the problem was that monsters were gradually expanding their power by taking advantage of those gaps.

Then one day, in order to completely exclude him from the line of succession, the Crown Prince promoted a marriage with the noble young lady of a family that supported him. It was Riley.
