In the story, Tōma Kamijo is an ordinary high school boy with terrible academic scores and a power called Imagine Breaker. Imagine Breaker can defeat any other power, but it also undermines Kamijo's own good luck.

The girl says she is being chased by sorcerers, and Kamijō learns that the girl is a Church of England nun whose memories have been forcibly replaced by Index- Librorum-Prohibitorum - the 103,000 forbidden texts of the Church.
