"—Me, the Great Saint? That can't be true, can it?"

In a world where the Great Saint who presides over the Great Clock Tower is revered,

Duke Veronica is recognized as the current Great Saint and, as a "Great Saint candidate," becomes engaged to the Crown Prince Derek, whom she despises.

The condition for breaking off the engagement is to awaken the abilities of the Great Saint by the time she turns eighteen.

With the help of her childhood friend Edzel, she works hard every day, but it's not going well.

Meanwhile, she hears rumors that Baroness Flora is the true Great Saint and is engaged to Edzel.

Veronica is at a loss.

But at the academy graduation party, just before she turns eighteen, Derek suddenly tells her:

"I'm breaking off our engagement!"

A new gear of fate begins to turn—!
