─The "Truth" approaches, like a creeping darkness─
About
Fifteen years ago, a serial family murder case shook all of Japan. Koichi Kurokawa, arrested as the perpetrator, died in prison while maintaining his innocence until the very end. Fifteen years have passed since then. Nagi Shiraishi, who became a lawyer following her father's death, quietly begins approaching those involved in the case. From that point on, the individuals connected to the incident start dying mysterious deaths one after another. A detective chasing the case senses Nagi's presence behind every event, yet cannot find a single shred of evidence to charge her. Eventually, a single "lie" covering the fifteen-year-old case and a "truth" known by no one are revealed. What awaits at the end of revenge—her father's exoneration, or a reality beyond salvation?

Intro
People seek the truth. But when they learn that the truth will hurt someone, they choose to lie.
Is a lie a sin? Or is it justice to protect someone?
Fifteen years ago, a single lie killed a man. And that lie took everything from a young girl. The girl grew up, studied the law, and became a lawyer.
Not to protect people. But to expose the truth and judge those who lied. Quietly, surely, the revenge begins.
This is not a story of those who believed in justice. It is a story of those toyed with by fate in the gap between truth and lies.
