Aruru is Elulu's younger sister, and Tuskaru's grandaughter. She is shy, and doesn't trust easily. This is especially true when she meets Hakuoro for the first time, as she goes out of her way to avoid him. However, she warms up to him before long. She even begins to call him, "Father."
Aruru has the ability to communicate with animals. She becomes the surrogate mother of Mukkuru, a baby white tiger (who soon grows into a VERY big tiger.) She also takes care of Gatchatarha, a meekchum (a creature that sorta looks like a cross between a ferret and fox but with two tails)
Aruru's two best friends are Yuzuha and Kamyu.
In summery, though Aruru is one the youngest characters, she possesses a stubborn will and a strong heart.
