Background
Koichi Fujita, the producer of the Omega Tribe project, scouted Japanese Brazilian singer Carlos Toshiki after being given a demo tape of Toshiki, with Fujita creating a new group part with Teruka Kurokawa, Shinji Takashima, and Toshitsugu Nishihara, the latter two were previous members of the band S. Kiyotaka & Omega Tribe. To help Toshiki get into the aesthetic of the band, as well as to get to know him better, Fujita took him to Hawaii. During the trip, Toshiki commented on the similarity between the Japanese word for "thousand" (千) and the Portuguese word for "hundred" (cem), which Fujita also found interesting, contacting a lyricist to create a song based on the pronunciations. During the recording of the song, Toshiki sang without understanding most of the lyrics.
