Derivative Unit

Kisumai has a derivative unit. Its name is 【Busaiku】 (read: bu-sa-i-ku). It was formed in 2013. Although the four members are now active in their respective fields, at the time, the gap between them and the other three members was severe, and their costumes were so plain that they were mistaken for "Jr.s". It was then that a former SMAP member (name withheld) reached out to them. When they appeared as guests on "Kisumai BUSAIKU!?", they offered to produce the four members and simultaneously provided them with a song. Their debut song is "Tana kara Botamochi". In addition to their regular TV appearances, they released singles and albums, and held tours, gradually increasing their recognition. If it weren't for that person, the current four members wouldn't exist.
