Hakuoro is the main protagonist who wears an irremovable mask over the top part of his head extended down to just under the eyes. He is found badly injured by Eruruu, who nurses him back to health. It is soon apparent that he has lost all of his memories, and he additionally finds that the state of the world varies significantly from his expectations (e.g. certain anatomical attributes are now considered normal, such as ears and tails). In place of his forgotten name, he is given the name Hakuoro (白皇, meaning "White Emperor" in Ainu, also the name of Eruruu and Aruruu's father). His main weapon of choice is a large metal fan that was given to him by Tusukuru. He quickly captivates and gains the trust of those around him, and soon finds himself in a growing position of leadership.
