In New Hope City, humans and bionic intelligences coexist under one absolute law: “Intelligences are strictly forbidden from harming humans.”
Until one day, the law is broken.
Top scientist Raymond is found murdered in his sealed room, and every piece of evidence points to an impossible culprit: an intelligence. Yet data from the Furnace System shows that every intelligence followed the rules perfectly at the time of the crime.
Is the System lying? Or is this the perfect crime?
Levi, a jaded detective with an intelligence prosthetic, is forced to take on this forbidden case. His partner is Ella, an intelligence assistant who is utterly composed.
During the investigation, Levi discovers that his prosthetic can sense eerie data phantoms beyond the Furnace. Ella, who seems to be there to assist him, also appears to harbor secrets that go beyond her programming.
“Trust me, Levi. My logic tells me the truth will overturn everything.”
“But what if logic itself is a lie?”
As they close in on the truth, deadly danger follows close behind. The mastermind seems able to predict their every move.
