C-ko  

Three female characters, referred to as A-Ko, B-Ko, and C-Ko, are seen only through silhouettes in each episode. They provide comic relief and offer insights into the show's plot by energetically commenting on its events using symbolic allegory. Their actions resemble those of a Greek chorus but their main impact is derived from shadow puppetry. C-ko has a headband and her hair tied up in a ponytail.
