Doll Licca is one of the three Doll Knights of the Doll Land present in the story. She's mainly the one used and is the title character of the series itself.

In the beginning of the story, when the young princess Licca gets into a tight spot, Licca's bracelet lights up to warn her grandmother; her grandmother then calls out for Doll Licca by chanting magic words -- -- onto her Calling Necklace and Doll Licca dashes out with a bright pink light.
When about to fight, she becomes human size (her outfit changing as well into something casual for easy movement) and fights using a yo-yo named "Light Spinner."

Her hair is puffy and pink with a few strands on her bangs with the colors orange and purple, and up on a ponytail; when in fighting mode, she has twintails on that's held up by a yellow band, with 2 ahoge-like hair poking out on each side, one with orange and purple.
