A disgraced, cynical cognitive scientist who can read micro-expressions is forced to team up with a brilliant but emotionally erratic rookie detective who cannot tell a lie. Together, they must solve the "Perfect Alibi Murders," where every suspect is clinically telling the truth.

Ren pulls up a photo of the victim, Kaito. He looks at the final expression on Kaito's face – captured by a security camera 0.5 seconds before death. It's not fear. It's surprise . And just before surprise, his eyebrows are raised in recognition . He knew the killer.

Ren zooms in on the reflection in Kaito's glass of champagne. A faint, distorted face.

The most dangerous lies aren't the ones we tell others – but the ones our own bodies tell us to protect our sanity.

Usotsuki wa Dare da? (誰が嘘つきですか？ – "Who is the Liar?")

Rin sits across from Ren and Mei. No lawyer. She's confident.

Re-watching the bodycam footage: The officer asks Sora to step out of the car. Sora's left hand holds the door handle. But his right hand – the one that would have touched the murder weapon – is clenched so tightly the knuckles are white. He's not hiding guilt. He's hiding muscle memory .
