Premise Hi Hi Puffy AmiYumi follows the adventures of two pop stars and best friends: Yumi Yoshimura (voiced by Grey DeLisle), a cynical, sarcastic, and grumpy tomboy and Ami Onuki (voiced by Janice Kawaye), a peppy, optimistic, and cheerful girly girl.

They travel around the world on their customized tour bus along with their well-intentioned yet greedy manager Kaz Harada (voiced by Keone Young).

Secondary characters include: Jang-Keng (voiced by Grey DeLisle) and Tekirai (voiced by Janice Kawaye), the duo's pet cats who enjoy tormenting Kaz; Harmony (voiced by Sandy Fox), a six-year-old girl who is the self-proclaimed "Number One Fan" of Puffy AmiYumi and (later) Kaz and constantly stalks them; Eldwin Blair (voiced by Nathan Carlson), a sinister land developer who tries to tear down beloved places for his own selfish needs; King Chad (voiced by Katie Leigh), a selfish "bad boy" who is a master of the card game Stu-Pi-Doh!
