Zuzu Boyle, known as Yuzu Hiiragi[5][9][10] (柊ひいらぎ 柚ゆ子ず Hīragi Yuzu) in the Japanese version, was a duelist and one of the main characters and a childhood friend of Yuya Sakaki in the Yu-Gi-Oh! ARC-V anime. She gives powerful pep talks. Her father owns You Show Duel School, the Duel school that she and Yuya attend, where they spend their time honing their Dueling skills. She functions as the straight man in comedy acts with Yuya.[11] Like Yuya, Zuzu has dimensional counterparts: Celina (Fusion Dimension), Rin (Synchro Dimension),[12] and Lulu Obsidian (Xyz Dimension).[13] She is also one of Ray Akaba's reincarnations, and later comes to assume Ray's identity after merging with all of her counterparts. Zuzu has blue eyes and dark pink midback-length hair, which she wears tied up in pigtails, clipped down by blue, spherical hair clips. Her hair also features two lighter pink bangs that fall to the side of her face. Zuzu's outfit consists of a sleeveless light-blue and white shirt with a green musical note on the right collar, along with a red tie, which she wears with a dark red skirt, dark stockings, and pink sneakers. Her skirt was lengthened in the dub to cover the bare skin showing on her legs but starting from the Arc League Championship Arc, her stockings are lengthened instead. She notably is not shown wearing the school jacket from Paradise Prep School that other female students wear. She also wears a bracelet with strange abilities. These powers seem to be connected to Yuya and his counterparts, activating whenever Zuzu, Yuya and any of his counterparts are in close proximity. Zuzu later switches clothes with Celina, but she retains her bracelet, her spherical hair clips and her Duel Disk. Later, she starts wearing some of Rin's clothes while staying at Yugo's orphanage in the Synchro Dimension: the first outfit was a pink top and yellow shorts. During the Friendship Cup, Zuzu wears one of Rin's Turbo Dueling outfits; a predominantly white one-piece short-sleeved jacket-miniskirt combination with light pink shoulder pads and hot pink markings, in addition to back pockets; long white gloves with light pink elbow pads that extend over her elbows, hot pink pants, and white knee-length form-fitting boots with light pink kneepads. While in the Underground Labor Factory, Zuzu wore one of the factory's uniforms: a dark red full body suit with a hood and brown shoes without socks. After arriving at the Fusion Dimension's You Show Duel School, Zuzu receives a change of clothes that once belonged to Alexis when she enrolled in Duel Academy: a sleeveless white shirt with a pink pad over her chest and shoulders, a pink skirt and a white belt similar to Tori Meadows', except with a different color scheme. She also wears white boots. As a little girl, Zuzu wore a pinkish dress with her bracelet hanging around her neck and had two blue flower hair clips tied to her pigtails before she used the spherical ones. Zuzu has a kind, strong-willed personality coupled with an extremely short temper, the latter often resulting in her actions causing huge consequences. An example of this would be when she smashed her fists down on the ARC System computer at You Show Duel School out of annoyance at how Yuya was Dueling, which ended up destroying the machine. Zuzu also has a tendency to smack people on the head with a paper fan, primarily Yuya and her own father, whenever they do something foolish.[1][14] She is also shown to be quite argumentative, wanting to argue with a spectator who insulted Yuya and his father before his Duel with the Sledgehammer, showing that she can be just as defensive and caring of Yuya and his belief in his father.[14] Her perception and judgment begin to falter after her successive encounters with Yuto, due to Yuto's resemblance with Yuya, and her lack of knowledge of the subject frustrates her.[15] These worries are put at ease after the encouragement from Yuto and Yuya, reinstating her resolve and wishing to protect You Show Duel School and her friends. She harbors feelings for Yuya, initially shown when she was blushing after Sora Perse mistook her as Yuya's girlfriend[16] and whenever Aura Sentia makes advances towards Yuya. The strongest examples so far included when she started to cry when she was worried that Yuya would never awake while he was unconscious for a few days after his encounter with Yuto and Yugo, and upon being separated from Yuya in the Synchro Dimension. Zuzu's kind, gentle, truthful personality with a strong sense of justice has made her a person that people from all four Dimensions adore and the one with the strongest bonds with non-Standard residents. Shay and Yuto care for her due to her likeness to Lulu, and Sora and Celina are protective of her as she is their first friend and opened their eyes to the lies and cruelty of Duel Academy. In the Synchro Dimension, she is known as Entertainment Angel loved by both Tops and Commons, and Crow's three kids and Chojiro deeply care for her by their own right. She serves as a catalyst for the protagonists' actions. While brainwashed by the Parasite Monster, Zuzu is emotionless and does not speak. Zuzu is quite athletic and acrobatic. In her debut, she was able to smash the Solid Vision technology to the point where it malfunctioned with one punch. When Zuzu refused to go with Yuri, she performed several backflips in quick succession and landed with ease. She was later quoted as having evaded Yuri throughout the entire night, a feat that he regarded as amazing. Zuzu and Yuya have been best friends since childhood. Yuya respects her greatly, and he is also grateful for her help over the years. Zuzu in return, is very supportive of Yuya and among his other friends. She is the one who hangs out with Yuya the most and often defends him when someone insults him. Whenever either of them gets depressed, the other is usually the one who gets them out of the depression. Though she cares about Yuya, Zuzu occasionally gets annoyed with Yuya's antics and whacks him with her paper fan whenever he does anything foolish. Zuzu blushed when Sora and Chojiro mistook her as his girlfriend. She hugged Yuya after her loss to Julia (only to push him away after Julia commented on the situation), and showed jealousy whenever Aura made advances towards him or called him "darling", though Yuya is oblivious to these advances. Her bond with Yuya is what drove her to become stronger so that she could protect her friends and You Show Duel School, and in return, this drove Yuya to push the boundaries of Pendulum Summoning. Yuya's feelings regarding Zuzu are more complex, but no less caring. Over the course of the series, there are many hints that Zuzu sees Yuya as more than just a friend, especially when she saw that Yuya was determined to bring her back to the Standard Dimension and end the Dimensional War against Duel Academy. The bond between them culminated in Zuzu's speech to Z-ARC that she believed that Yuya was not a demon despite being the reincarnation of the destroyer of the Original Dimension, allowing for Yuya to break free of Z-ARC's control and allow Ray/Riley to defeat him. It is therefore likely to assume that the two do have a mutual affection and love for one another. Zuzu is often annoyed by her father's goofy nature, which causes her to beat him with her paper fan. However, as father and daughter, they care for each other and Skip is shown to be a very supportive father, who often encourages her and cheers for her when she Duels. Zuzu in return promises that she will win. Skip cares deeply about his daughter, having raised her as a single parent and is distraught upon hearing of her disappearance. Zuzu uses a "Melodious" Deck, focusing on swarming tactics through cards such as "Sonata the Melodious Diva" and "1st Movement Solo", giving her early access to her ace, "Mozarta the Melodious Maestra". After her loss to Julia Krystal, she decided to learn how to Fusion Summon, and began practicing incorporating that strategy into her Deck, using cards such as "Soprano the Melodious Songstress", "De-Fusion" and "Fusion Cycle". She also included cards to work with her new ace, "Bloom Diva the Melodious Choir" such as "Pianissimo" and "Slow Tempo". She is also shown to utilize a large number of Fairy and LIGHT support cards as well as multiple copies of her "Melodious" monsters, shown when she dropped her Deck.
