Juvia made up 1/4th of the Phantom Lord's elite group, Element 4. She was sent by the guild master Jose, along with Sol, to go and capture Lucy and bring her back to him safely. Her magic seems to deal with water as she is able to control rain and other large bodies of water. In addition, her body seems to be formed from the rain that surrounds her, leaving her intact and able to reform herself after attacks. Her nickname is also Juvia of the Sea, which correlates with her water controlling magic. When angry she can also control hot water. Juvia also often refers to herself in the 3rd person. Juvia has developed a crush on Gray, and due to a misunderstanding, views Lucy as her rival in love. After being defeated by Gray, the rain above her finally clears up which she thought was beautiful.

After the fight, her deep infatuation with Gray continues, secretly following him wherever he goes. In the Tower of Heaven arc, she mentions to Gray that she is now an independent mage once more, but Gray notes that she has probably has her eyes set on Fairy Tail. She is quite willing to do anything for him.

She is the only member of the Element 4 to be shown after the Phantom Guild arc. The Spanish word "lluvia," which is pronounced like her name, means rain.
