In this world, there are cases that the ordinary police cannot handle.

These are "Mystic Crimes" involving magic, spirits, mythology, and cursed tools.

The culprit might not be human, but a spirit. The murder weapon might be magic. The locked room might be created by spatial sorcery.

There is an organization that specializes exclusively in such inexplicable cases—

The Mystic Incident Investigation Bureau, Aegis.

The detectives belonging to the bureau each possess exactly one special ability.

However, none of these abilities are suited for combat; at first glance, they seem entirely useless.

"I can talk to flowers." "I know who last read this book." "I can hear the sounds of yesterday."

Through extraordinary deductive reasoning, they transform these small abilities into "evidence."

Eventually, they learn that a certain entity is involved behind the Mystic Crimes occurring across the globe.

—Its name is Judgment.

A legendary existence that nearly destroyed the world a thousand years ago.

This is the story of detectives who expose the truth not through power, but through wisdom.
