In her human form, Juliet is a youthful woman with a childlike figure, unlike her partner. She has orange hair in short pigtails that are held up with brown bows, with straight-cut bangs hanging slightly over her face. She wears a white coat with golden border straps surrounding the cuffs on the coat, waist area, biceps area to go along with two gold lines streaking down the chest area, ending in a skirt with golden frills at the end. She wears white fur-lined snow boots with golden straps to go along with matching white pants.
In her true form as a sword, Juliet appears as a simple white sword with an intrinsic design streaking down on the guard handle.
Unlike the more serious nature of her partner Heine, Juliet is more of a happy-go-lucky character, speaking freely towards their leader Irene's birthplace when the latter speaks of some of its history. She likes to giggle commonly and also is somewhat ditsy, with her not properly diagnosing the compliment from Irene of being the "white angel" she spoke of, claiming she wanted to be its counterpart. Due to her kooky nature, she can retort back from an assignment, even one ordered by one of her superiors, as well as wanting to take out those higher in power before the lower tier, promoting her and Heine's strength saying it would overbearing for them to join the war with their power; a demonstration of her overconfident persona when it comes to battling. She also is absent of denoting the proper honorifics to the other Spriggan 12 besides Irene, leaning credence to her informal actions and a vast difference in tone unlike her partner.
Alvarez Empire arc
Juliet, along with the rest of the Irene Squad, are sent to eliminate Ishgar's resisting northern forces, successfully defeating the first wave. While Irene talks about an old folktale of Mt. Zonia, she gleefully compliments her knowledge of the country, only for her partner to chastise her for talking so freely of their leader's birthplace. Juliet questions Heine if she was in the right to mention it as well, while Irene likens the comparison of the black and white angel she spoke of to the duo; Juliet exclaiming she wants to be the black one. Irene then wonders who would come out victorious between the two girls, only to mention it was only a joke, calming their nerves. Juliet then watches Irene completely alter the snowy mountain's climate, cheerful at the expected power of her leader. Juliet watches the battle proceed from afar with Heine and Irene. She and Heine express their worries at the Ishgar forces' comeback, but Irene calmly states that they've nothing to fear as Bloodman and Larcade are there as well.
Irene orders Heine and Juliet to join the battle as for she, will retreat the battlefield. After Juliet questions Irene about why they should join the battlefield since they have Bloodman and Larcade, Irene proceeds to explain to the duo that they have four guests: the first being the tigers and pegasi, the second being the fairies, and third being Crime Sorcière. However, the fourth guest is the most troublesome, and says she must take care of him herself, causing Heine and Juliet to say that this fourth guest must be a fool for daring to face her leader Irene. Following her master's use of Universe One, Juliet and Heine are warped to the site of Fairy Tail's battle with Alvarez forces, where they quickly subdue some of Fairy Tail's lesser members; Juliet suggests they take out Makarov, but she quickly notices Mirajane and her Magic Power, after which she makes a comment on the latter's beauty.
As the Fairy Tail Mages make for their guild, Juliet makes the first attack against Mirajane and Lisanna, with Heine trying to take Mirajane for herself, an action which upsets Juliet. However, Mirajane breaks free in her Satan Soul form and attacks the two, though they are relatively unharmed. The fight continues, with Juliet and Heine overwhelming Mirajane with the combination of their Magics; after they degrade her, Mirajane unveils her incredulously strong Satan Soul: Mirajane Alegria, and the astonished and frightened Juliet and Heine are defeated in one hit by the Fairy Tail Mage. After she is defeated, Juliet turns into a white sword, revealing herself to have been an Enchantment of Irene's making.

Mucus Magic (粘液マジック Neneki Majikku): Juliet has shown proficiency in producing a gooey-like substance, which can be manifested from the ground, her hands, or on people, making it sticky and slippery for those contacted by it.

- (To Irene Belserion): "Wow, Lady Irene! I'm surprised you're this well-versed on the old folk tales of this puny country!" 
- (To Irene Belserion): "Eeehh? Why do we have to go~?! They've got Bloodman and Larcade, don't they? Sending us would be overkill..."
