As Yuni, she tends to prefer being a lone wolf and generally holds a strong responsibility for herself mainly rooted from the guilt she has of being unable to save her planet Rainbow, rejecting her friends' kind offers and assistance in the beginning and blaming herself when she fails to accomplish her goals, but she gradually warms up around them as the series goes on. Despite all this, Yuni is still kindhearted, and she would help and rescue the needy.
