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''.
