Neo-Kyoto hides its crimes in light. Genius forensic scientist Dr. Rei Tanaka hunts them with nine holographic koi: living algorithms that swim the city's data currents and circle the truth.
Dr. Rei Tanaka built forensic AI the police banned. Now she works alone from a glass tower, reading crime scenes the way the city refuses to.
Nine holographic koi, living algorithms she grew from light. Each fish follows one thread of evidence through the city's data currents.
A vertical city where memory is currency and every window is a witness. Someone is erasing people from its light, one life at a time.
