How Did the Witch Raised by the Priest Turn Evil?

Caterina, the Calamity Witch who had been wanted for twelve years, has finally been captured.

This should have had nothing to do with the priest Bright, but when he received a mission and hurried back to the temple, he saw a shrunken, fourteen-year-old Caterina and felt the pressure of life all over again.

Bright: "?"

Caterina, the Calamity Witch, killed, burned, and unleashed disasters everywhere, spreading corruption across the continent of Theles. Even before her capture, she had to get one last dig in at the Church.

"The magic array I set up will keep releasing dark mana. My dark magic will devour the entire continent!"

As he watched a recording of Caterina's memories, Bright expressionlessly tapped her on the head.

"You've given me more work and ruined my vacation," Bright told fourteen-year-old Caterina. "So now you're going to help me clean up the mess you left behind."

Twenty-six-year-old Caterina: powerful, insane, and mentally unstable.

Fourteen-year-old Caterina: weak, pitiful, but with a healthy appetite.

The hapless Bright sets out with Caterina on a journey to uncover the truth.

And so begins the story of a deadpan, goofy priest who solves problems with physical force and an amnesiac witch who hides her dark side behind an innocent facade, taking a government-funded trip together.
