Edit
One of the many Exit Tunes mascot characters, appearing mainly on their Exit Trance album covers. Was among its larger mascots, having her own merch and even her own Twitter. Her name is also written as Barusa Miko.
Named after one of the Japanese misheard lyrics to Caramelldansen; in the chorus, the first line goes "Dansa med oss. Klappa era händer," but it was misheard as "バルサミコ酢 (Barusamiko-su), やっぱいらへんで (Yappa irahen de)". She appears on the "Exit Trance PRESENTS ウマウマできるトランスをつくってみた (Uma Uma Dekiru Trance wo Tsukutte Mika)" album series, similarly named after the misheard lyrics in Caramelldansen. She's also on the cover of the album "EXIT TRANCE PRESENTS ウマウマできるトランスを作ってみた2 作者は病気シリーズ", which features the remix of the song Caipirinha that also became a meme.
Loosely inspired the original design of one of the Caramella Girls, Nadine.
