In human form Plutia is very calm. Almost always seeming tired. This is most noticeable by the fact that she speaks rather slowly. She is kind and somewhat of a ditz but with minor sadistic tendencies. Much like Neptune, she tends to leave her duties as goddess ignored and spends most of her time either sleeping, making dolls, or playing around with Neptune. In Her goddess Iris Heart form is sadistic dominatrix which earned her the name “Sadie” from Neptune. She's friends with neptune.
