Since successfully developing powerful magic, the empire has continued to wage wars against neighboring countries to expand its territory.

Due to something as a dividing line, the empire's princess Canaria and her attendant Iora were driven to live in an isolation hut.

In her boring daily life, Canaria accidentally saw prisoners of the neighboring knights being brought into the city.

So, Canaria said to her father, the emperor──

"I want that person."

The princess's life trajectory intersects with the hearts of the two men.
