Eruruu is the female protagonist, though there are other main female characters in the story. She was the first person Hakuoro meets when he wakes up after being found by her. She nurses Hakuoro back to health until he is strong enough to go walking outside, with much initial assistance provided by Eruruu and a walking stick. Later, she falls in love with Hakuoro. Eruruu has a forceful, but caring and gentle personality. She is named after a flower that only exists in the story. In the game and manga, she is often found displeased of her small breast size. Eruruu kisses Hakuoro before he is sealed, as he tells her that they will meet again and that she'll be waiting for him. At the end of the anime, she continues as a healer and is awaiting Hakuoro's return. In the last scene she turns around and sees someone or something, however it 's not shown clearly who it is. It's implied by many to be Hakuoro without Witsarunemitea's mask. In the game version, this is strongly implied as prior to that scene, Kuuya, Camyu and Aruruu are all shown acting as if they saw Hakuoro again. Eruruu's past self: Eruruu is the reincarnation of Mikoto who was an artificial being based from Iceman's body/blood. She was the only woman he ever loved and had a child with her, though they both were captured. She was later butchered by scientists for research. Her name is derived from the number 3510. The word Mikoto can also be pronounced as ''inochi'', meaning ''life''.
Kurou is the second-in-command of Benawi's cavalry. When the first emperor falls, he remains loyal to Benawi, and, in turn, to Hakuoro, to whom Benawi swears allegiance. Kurou tends to be a source of comedic relief of the anime, usually seen either arguing with Oboro, helping to plan military actions, training with his men in the courtyard or on the battlefield, by Benawi's side. His main weapon of choice is a thick longsword which he uses very effectively and with great skill in battle. He always calls Hakuro "Commander" when speaking to him, and always calls Benawi "General", even when Benawi's rank was taken by Nuwangi for a time. In the OVA, it is revealed that he has a thing for young, petite girls.
Lt. Commander Yuriko Star is another by-the-book officer. Yuriko joined the UPSF to give her life structure and attepts to obey the rules in almost every situation. However, she, unlike Yamamoto, has no problem telling Tylor that he has done something wrong and will even resort to slapping him when he gets too far out of line. Yuriko also tries to downplay her gender, making herself a soldier first, and then a woman. This is a sore subject for her when someone comments about Tylor's obvious attraction to her looks, pointing out that she has never used her appearance to get ahead; an equally sore point for her is her budding attraction to him. Yuriko is one of the most rational and level-headed officers on the Soyokaze. While she is senior to Yamamoto, her speciality as an intelligence officer places her outside the chain of command.
Justy Ueki Tylor joins the United Planets Space Force hoping for an easy ride through life but with the devil's luck becomes a hero. He is soon promoted Lieutenant Commander and Captain of Soyokaze. Tylor is a irresponsible laid back captain that can always find his way out of trouble unscathed. Tylor normally allows his crew to "bend" the rules such as letting the surgeon drink while on duty. Throughout the ranks it is argued that Tylor is either the most brilliant military mind or just a lucky bafoon.
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. Major SpoilersAlthough it seems for a time that his identity is Rakshain, a murderous traitor, it is eventually revealed that he is the embodiment of the good half of the god Witsarunemitea and he recalls his memories as Iceman. After Hakuoro's final battle with the darker half of Witsarunemitea, the halves join together once again, with Hakuoro's side straining to maintain dominance. He decides to seal himself away so that his other side will not cause anymore destruction, and bids farewell to each of his comrades. Eruruu confesses her love for Hakuoro and the two share a kiss. Hakuoro says that he will return back to her and Eruruu says that she will wait for him. The conclusion hints that Hakuoro returns through the final scene with Eruruu, though not really seen. Other Names: Iceman/Witsarunemitea In the earliest of Hakuoro's memories, he is seen as an archeological research scholar who stumbled upon Witsarunemitea's fossil hidden in an advanced laboratory. An unknown scientist catches him and explains that he did not want anyone to know of this forgotten deity; the "missing link" in human evolution-- for he felt that it should not exist. To protect its concealment, he shot the archeologist and his blood landed on the fossil. Witsarunemitea then awakened and restored him in exchange for taking his body as a vessel so that he will not be disturbed again. As a symbol of the contract, he acquired the mask which represents Witsarunemitea. Much later, his frozen body is found by researchers who unfreeze him and name him 'Iceman.' Although initially under the pretense of helping him, the researchers were actually interested in researching his ability to survive outside of a greenhouse environment and interested in further increasing their longevity. Artificial beings based from his body were created for further studies, including subject #3510 whom he named "Mikoto" and #63 whom he named "Mutsumi." Iceman fell in love with Mikoto and later on escaped with her and had a child with her; although they're both eventually recaptured. The scientists dissected Mikoto to experiment on her, which caused Iceman to go into a rage and awaken his abilities as Witsarunemitea. Realizing what he is doing, he asks Mutsumi to destroy him; but she is unsuccessful. Instead, she manages to seal him, but he is separated into two: Hakuoro possessing his good side and his human form; and a formless evil side that must possess a host body to gain physical form. However, the seal cannot hold them forever and the two halves periodically become free. In the current time, Hakuoro awakens with no memories, and the latest of the forms taken by the darker side is that of the Onkamiyamukai scholar Dii.
