Kihal is a young girl hailing from a small island. Her village is known for it's beautiful messenger birds with oceanic blue and green feathers. Kihal has her own bird, Popo, that she controls with her flute, called a Walnut Stone. She despises nobles for the acts they have done on her island. They hunted the birds ignorantly and cared nothing for the islanders. Kihal enters the story by going to Clarines to complain about this problem, but only to be tested in the process.
