 Hi Hi Puffy AmiYumi follows the adventures of two very cool, but very different, pop stars as they travel from gig to gig or just hang out in their hometown, Tokyo. Being famous rock stars, Ami and Yumi tour the globe in their customized Puffy bus, a veritable condo on wheels with all the major amenities and an ever-changing interior. Ami is the peppy, positive and resourceful one. Yumi is the hard-rocking, no-nonsense cynic with an absolutely infallible sense of cool. Together, these superstars take the world by storm with musical talent, trend-setting style and humor, despite occasional misjudgments from their well-meaning but tragically square manager, Kaz. Whether they re jamming with aliens, being chased to the center of the earth by an obsessed fan or getting knocked into a video game by a tsunami, Ami and Yumi always come out on top - dishing out lessons in J-pop justice and the international language of "cool" along the way.
