Karakuri Circus (Japanese: からくりサーカス, Hepburn: Karakuri Sākasu; lit. 'Mechanical Puppet Circus') is a Japanese manga series written and illustrated by Kazuhiro Fujita. It was serialized in Shogakukan's shōnen manga magazine Weekly Shōnen Sunday from July 1997 to May 2006, with its chapters collected in 43 tankōbon volumes. The series follows Masaru Saiga, a young boy who inherits a vast fortune and dreams of becoming a puppeteer; Narumi Katō, a martial arts expert afflicted with Zonapha syndrome-a mysterious condition that halts his breathing unless he elicits laughter from others; and Shirogane, a silver-haired woman serving as Masaru's caretaker, who manipulates the puppet Harlequin.
