Erurū. Erurū is a physician in training who often helps Hakuoro in much the same way a secretary or even a mother would. She has a forceful, but caring personality which is how she acts most of the time, especially around her younger sister Arurū who she cares for deeply. Arurū is a playful young girl who is shy and quiet, usually only saying a word or two when spoken to. After the god of the forest, Mutikapa is killed, Arurū raises her child as if it were her own, naming it Mukkuru. Since Erurū was the one who initially cared for him, Hakuoro regards her and her family the closest thing to a family of his own.
