Juvia Lockser is a Mage of Fairy Tail, formerly an S-Class Mage of the guild Phantom Lord.
Juvia is a young woman with blue hair, dark blue eyes, pale skin and a curvaceous figure. Juvia is first introduced with long hair, tightly curled at the base, wearing a navy blue coat, a fur shawl with a teru teru bōzu attached to it, as well as a Russian Cossack hat. Upon becoming a member of Fairy Tail, she cut her long hair and began to wear more revealing clothing. However, after hearing about Gray Surge's crush on her Edolas counterpart, Juvia then returns to her original appearance with the exception of the teru teru bōzu, instead wearing 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, she also start to wear more revealing dress in variation from her signature navy blue dress coat.
Juvia is first introduced portraying an emotionless face, seeming more secluded from everyone including members of the Phantom Lord Guild. After she joins Fairy Tail, she develops a happier demeanor. She is obsessed with Gray Fullbuster and when Meredy threatens him, Juvia loses her generally calm demeanor and enters a somewhat satanic-appearing state that frightens Meredy and even Erza. Juvia also seems to have a slight masochistic side; upon making a mistake, she asks Gray to spank her as punishment, saying it's her "hobby" while Gray says it isn't his. She's also very polite towards other, typically addressing others with honorifics, though she addresses Gray as "Gray-sama" only.
She cares deeply for Fairy Tail and its members. During the Fighting Festival arc, Juvia is pitted against a fellow guild mate, but instead chooses to K.O. herself by attacking a thunder lacrima, even though she knows that it will cause her harm. Upon entering Fairy Tail, she wasn't feared or hated for her past relationship with Phantom and she maintains 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. Juvia has a wild imagination in which she tends to fabricate relationships and love rivals.
