Blanca was the twenty-first monster to battle Greenman. It was created by Tonchiki and sent to get children's blood for Maoh. Tonchiki and Blanca teleported near a group of kids, who used their Green Calls to call for Greenman. The hero fought Blanca and almost defeated it before Tonchiki made the monster grow with one of his spells. Greenman also grew to finish off the monster. Eventually, Blanca was defeated and the children were safe once more.
