In this world, there are individuals referred to as "Minimum Holders" who possess unique abilities known as "small miracles." These people are trained by an elite government-funded academy to reach their full potential and serve the national interest. One such individual named Nice dropped out of the academy and started his own private investigator team with Hajime, content in solving cases for clients that often involved Minimum Holders. Murasaki, a top student at the academy, is tasked with bringing Nice back despite initially bristling at the idea that he had greater potential than she did. Eventually, Murasaki becomes involved in Nice's detective activities.
