A graduate student in criminal psychology who knows every plot point of Detective Conan transmigrates to a month before the story begins. He thinks he has the "divine script" in his hands and can rewrite every tragedy.
But every well-intentioned intervention is like a stone tossed into a lake, sending out ripples no one can predict. Cases veer off course, criminals change their motives, and even the endings become unrecognizable. The "script" in his mind grows worn and blurred with every revision.
He is no longer an all-knowing bystander, but a "variable" at the heart of the fog. On one side is a mysterious "Observer" trying to keep events on their original course. On the other is a rising star in the Black Organization, codenamed "Charon," roused by the anomaly in the timeline.
Under Shinichi Kudo's sharp gaze and amid Ai Haibara's wary probing, he must walk the tightrope he has twisted with his own hands before his memories disappear completely. This is a paradox about "knowing" and "changing," a deadly mystery set in motion by the flap of a butterfly's wings.
When the script is torn to shreds, can you still trust your memories?
