アルルゥ

Aruruu is Eruruu's shy, quiet younger sister, and a friend to Yuzuha and Camyu. Like Eruruu, she is also named after a fictional flower. It is said that the Eruruu and Aruruu flowers only grow together. When she first meets Hakuoro she is shy, running and hiding from Hakuoro at every opportunity and speaking very little. After Hakuoro eventually wins over Aruruu's affections, she calls Hakuoro "father".

Aruruu raises Mutikapa's baby tiger, naming it Mukkuru. After it grows (in an astoundingly short period of time), she begins to ride him into battle, often in spite of orders or warnings to stay away from danger.

It is later revealed that Aruruu had been severely injured presumably from an earthquake prior to meeting Hakuoro. Uitsualnemetia healed her in exchange for Eruruu's body and soul. She is also heavily wounded and presumably killed by an attack from Hauenkua, but is revived by Hakuoro in his aspect as Uitsualnemetia.
