The characters in Hi Hi Puffy AmiYumi
, on which this game is based on, were inspired (not directly) by the Japanese duo PUFFY, known in North America as Puffy AmiYumi (to avoid confusion with Sean "Puffy" Combs
), and their manager Kaz Harada. Although Ami Onuki and Yumi Yoshimura did not voice their animated selves, they did appear in branching segments in the series. Onuki and Yoshimura also appear in Kaznapped!
, in a series of still photographs.
