The anime revolves around three girls — Mai, Ruri, and Kei — who are into music and dance, Ryubu or Okinawan stage productions, and karate. Long-time voice actress Noriko Hidaka (Touch's Minami, Inuyasha's Kikyo, Ranma ½'s Akane, Aim for the Top! Gunbuster's Noriko) plays the title role of MiRiKa — a name coined from Musical, Ryubu, and Karate.
