GGK (voiced in Japanese by Misaki Kuno and in English by Mela Lee with singing vocals by Madison McFerrin) is a character in the anime series Carole and Tuesday.  GGK is an eccentric contestant on the Mars' Brightest talent show, claiming to be a vessel through which the universe itself sings.  During her performances, her all black costume shimmers like it's part of the fabric of the universe, while she claims the red dot on her forehead is actually her third eye.
