A murder that should never have happened leads him to discover that the world contains errors that cannot be recorded.
When everyone else chooses to forget, he is forced to remember the truth.
In reality, he is an investigator excluded by the System; in his dreams, he enters an abnormal world called the Abyssal Realm.
From being drawn in against his will to taking control of his abilities, he solves cases across two worlds, pays the price, and fights against reality's attempts to correct itself.
When the first shocking conspiracy comes to light, he realizes that the real enemy is not any one person, but a world being forcibly kept "normal."
