After passing the company's audition, she moved on her own from Osaka to Tokyo, where she eventually met Ōnuki by chance in the Sony Music offices.

Although Ōnuki had recorded a solo CD under the guidance of former Unicorn frontman Tamio Okuda, which later become half of solosolo, she and Yumi requested Sony pair them as a duo.

Asked if they were surprised by the attention after its success, Yumi told an interviewer "... everything that was put together for that song all came together and made it happen, but we didn't expect it.

[7] Soon after their SXSW performance, attorneys for Sean "Puffy" Combs sent the band a cease and desist letter asking them to change their name.

We were given our name by somebody else (Andy Sturmer) six years ago, and we really don't have a clue.After Pa-Pa-Pa-Pa-Puffy ended production in 2002, Puffy AmiYumi focused on performing in the United States.

Several of their previous Japanese albums were released for the US market and they recorded theme songs for the animated series Teen Titans and SD Gundam Force.

Despite both of them being voiced by American actresses (although Janice Kawaye, who plays Ōnuki, is of Japanese descent), the real Puffy AmiYumi star in short live-action segments video-recorded in Japan.
