Narumi Katou, in a bear costume promoting the Straw Circus, encounters Masaru Saiga, who accidentally triggers Narumi’s Zonapha attack. Masaru’s laugh saves Narumi, but he’s kidnapped by men in black suits. Narumi rescues him, escaping by train. Masaru shares his father’s death and inheritance tied to Karakuri puppets. On the train, they’re attacked by puppets, revealed when one is destroyed. Masaru summons Shirogane, a harlequin-clad woman, who uses the puppet Harlequin from his suitcase to defeat the attacker. Shirogane takes Narumi and the unconscious Masaru to a clinic, while a pursuer deploys the puppet Pulcinella.
