エルルゥ

Eruruu is the first person Hakuoro sees when he wakes up after being found by her and her family. She nurses Hakuoro back to health until he regains his strength. Eruruu has a forceful, but caring, personality. She is named after a fictional flower and has dog-like ears and a tail.

She is the descendant of Mikoto. Eruruu kisses Hakuoro before he is sealed as he tells her that they will meet again and that she will be waiting for him. At the end of the story, she continues as a healer and is awaiting Hakuoro's return. In the last scene she turns around and sees someone or something not shown to the reader. It is commonly theorized to be Hakuoro without Uitsualnemetia's mask.
