At the start of their career, one or both of the tracks on Up Up Girls (Kari)'s indie singles would be initially released as a Kari (仮; Temporary) version or event single available only through Up Up Girls events and e-Line UP!. This (Kari) version would later be released digitally, before the track was completed and announced for release as a track on the indie single. When the group switched labels from UP-FRONT WORKS to T-Palette Records in 2012, this system was dropped.
