Trivia

 * The group name was adapted from the sentence "unique maidens who train every day" (日々鍛錬する個性豊かな乙女達). "Ren" (錬) means to train while "jitsu" (日) means day, "oto" is an abbreviation of "otome" (乙女) meaning maiden, and "Ko" (個) is taken from unique (個性豊) while "iro" (色) means color. The group name itself isn't a coherent phrase, but its meaning can be pieced together to convey the original sentence.
 * They were originally planned to debut in April 2020, but it was postponed due to the COVID-19 pandemic.
