Juvia is a young woman with blue hair, black eyes, pale skin and a curvaceous figure. When she was first introduced her hair was tightly curled at the base, and she wore a navy blue coat, a fur shawl with the Teru teru bōzu attached to it as well as a Russian Cossack hat. After she joined Fairy Tail, she cut her long hair and wore more revealing clothing.
However, when she heard Gray Surge had a crush on her Edolas counterpart, she began to wear her old outfit and hairstyle again, except for the Teru teru bōzu which she exchanged for a Fairy Tail emblem. Juvia's Fairy Tail Guild Stamp is above her left thigh.
By the time of the Grand Magic Games, Juvia seems to have let her hair fall freely past her shoulders in a wavy style.
When first introduced, she displayed an emotionless face and seemed more secluded from everyone including members of the Phantom Lord Guild. After joining Fairy Tail, she develops a happy demeanor She is obsessed with Gray Fullbuster and when Meredy threatened him she lost her normally calm demeanor and entered a somewhat satanic appearing state that even frightened Meredy and Erza. Juvia also seems to have a slight masochistic side, wanting Gray to spank her as punishment for a mistake, and saying it's her "hobby" when Gray said it wasn't his.
She cares deeply for Fairy Tail and its members. When she entered Fairy Tail, she isn't feared or hated for her past relationship with Phantom and she has a good relationship with the other members. She is also shy about her body, as she didn't like to shower with other girls. Juvia tends to refer to herself in third person, and often says "drip, drip, drop" due to the rain she used to bring with her.
Prior to Fairy Tail Series, uvia was born in the year X767, and spent her childhood shunned by the other children for constantly making it rain around her. She took up making teru teru bozu dolls in an attempt to make it stop raining, but it only served to make the other children tease her even more. As she grew older, she would overhear other people commenting on the gloominess of the rain around her, making her feel increasingly depressed. At one point in her life she was in a relationship with Bora, but he broke up with her because he couldn't stand the rain. Eventually, she was accepted into the Phantom Lord Guild, noting that it was the first time anyone had accepted her, and formed a quarter of the guild's elite Mage team: Element 4.
Phantom Lord Arc
The Phantom Lord Guild proclaims war on Fairy Tail by destroying their guildhall and hurting their Shadow Gear team. After the attack, Jose Porla tasks Juvia and Sol with capturing Lucy Heartfilia, the duo found her as she leaves the infirmary where the members of Shadow Gear are being treated. Juvia initially does not recognize Lucy and walks past her after a brief meeting, prompting Sol to identify their target for her. Lucy prepares to fight the two members of the guild that hurt her friends, but Juvia captures her with her Water Lock spell. With their mission complete, Juvia and Sol bring Lucy to their master. Later, during Phantom Lord's attack on Fairy Tail, Juvia is stationed inside the guild's mobile fortress, which has transformed into a giant robot -the Super Mage Giant Phantom MK II- to help cast the forbidden Abyss Break spell. She appears before Gray Fullbuster, who has infiltrated the base in search of a way to stop the robot. Upon laying eyes on him, Juvia becomes attracted to him and is reluctant to fight him, instead asking him to bring Lucy to her to spare herself from having to hurt him. However, Gray refuses, saying he would give up his life to protect her. Juvia immediately misinterprets Gray's resolve and is under the impression that he and Lucy are an item, which prompts her to declare Lucy as her unforgivable rival in love. During the fight that ensues, Gray manages to freeze Juvia's body, but accidentally gropes her breast and unfreezes her in embarrassment. Moved by his apparent kindness, she tries to confess her fondness of him, but instead causes it to rain even harder; Gray thoughtlessly remarks on the gloomy weather. Now thinking Gray to be as uncaring to her as everyone else who has teased her throughout her life, Juvia attacks him in a vengeful fury, but Gray, determined to win, manages to once again freeze her boiling body with his Ice Geyser. The shock of her defeat snaps her out of her anger and depression, causing it to stop raining. For the first time in her life, Juvia is able to see the clear, blue sky, the beauty of which moves her to tears. She then spontaneously falls in love with Gray all over again and, overwhelmed, passes out. Her defeat subsequently slows the casting of the Abyss Break spell, which stops entirely after all four members of Element 4 are defeated. Following Juvia's defeat, Phantom Lord loses the war against Fairy Tail and is consequently disbanded by order of the Magic Council, leaving Juvia as an Independent Mage. However, her obsession with Gray remains, causing her to stalk him and leave him boxed lunches at any given opportunity.
