The show compresses 43 volumes into 36 episodes and it shows, but what survives the crash landing is pure character archaeology. You watch broken people, a kid with a death curse, a man running from his own puppets, a woman erasing herself from existence, actually heal across the series. The ending pays off every single person you've learned to care about, which is rare enough that it stops mattering how fast you got there.
Masaru inherits his father's vast fortune and immediately becomes a target. Assassins descend on him, but they're no ordinary killers: they're intricate wooden automatons built for violence. When a street fighter named Narumi stumbles into Masaru's life trying to help, he realizes brute force won't cut it against these mechanical horrors. Enter Shirogane, a mysterious protector arriving from France with her own powerful puppet weapon, Arlequin, designed to battle the mechanical threats hunting the boy. What begins as a simple matter of protecting an inheritance spirals into something far deeper. The puppets aren't random instruments of death. They're connected to something older, something that demands answers about why they exist and who truly controls them. Narumi, Masaru, and Shirogane find themselves pulled into a sprawling conspiracy spanning continents and decades, where magic and machinery blur into something neither science nor superstition can fully explain. The series balances genuine thriller moments with mystery as the trio uncovers layers of deception and discovers that survival means learning the truth behind the circus pulling invisible strings.
