A puppeteer and his doll solve murders together, and the soundtrack does more work than the actual mystery plotting. The real hook is watching Sakon treat Ukon like a person while everyone else sees wood and cloth, then the show slowly suggests maybe they're right to wonder what Ukon actually is. By the end you're invested in their partnership more than any case they solve, which is exactly how it gets away with recycling familiar mystery beats.
Sakon Tachibana carries on his grandfather's legendary legacy as a master puppeteer, but his real partner isn't human. Ukon, an intricately crafted doll from the Meiji period, serves as both Sakon's closest confidant and the key to unraveling Tokyo's darkest secrets. When bodies pile up across the city, the two find themselves drawn into criminal investigations where supernatural occurrences blur the line between puppet and reality. Each case pulls them deeper into a world where nothing is quite what it seems. Sakon's skill at reading people rivals his ability to manipulate his creations, while Ukon's perspective as a living artifact provides insights no ordinary detective could access. Together they navigate murders steeped in obsession, possession, and the twisted motivations of Tokyo's underworld. The series balances psychological horror with genuine detective work, creating an atmosphere thick with dread and uncertainty. Viewers drawn to period-tinged mysteries wrapped in supernatural unease will find themselves captivated by how expertly Sakon and Ukon expose the puppeteers behind each crime.
