Aruruu is Eruruu's younger sister. She's very shy and overall quiet. Like Eruruu, her name is taken from a fictional flower, saying that the Eruruu and Aruruu flowers grow together. After Mutikapa, a large, white tiger that is nearly invulnerable to small weapons, is defeated by Hakuoro, she tends to her baby tiger whom she names Mukkuru. Mukkuru grows in a very short time and becomes Aruruu's mount in battle. She is a Yaana Mauna, one with a natural talent for understanding animal's feelings and is able to converse properly with them. This talent is what allows her to command Mukkuru, the son of a divine beast.
~!She is the sister figure to Kuon due to them sharing the same father, which is Hakuowlo, although not related by blood.!~
