Ruri Kurosaki

Ruri Kurosaki ( Kurosaki Ruri) is a character in the Yu-Gi-Oh! ARC-V  anime. She is the Xyz Dimension counterpart of Yuzu Hīragi (from the Standard Dimension), Rin (from the Synchro Dimension), and Serena (from the Fusion Dimension). Ruri is Shun Kurosaki's younger sister and one of Yūto's dear comrades. Currently, Ruri is in the captivity by Leo Akaba.

Appearance
Ruri has very long, dark purple hair; it extends past her lower back, even when secured with a winged-shaped barrette in a loose bun, and wears feather-shaped earrings. She also has shorter lilac side tails, sunny, pale skin and pink eyes. Ruri wears a pale, vest secured with a same coloured belt. Underneath, she wears a three-split, periwinkle dress and black pants; both held up by two brown belts. She wears her long, Resistance scarf hanging from the right side of the belts. Her clothes are accompanied with brown boots covered in buckles. Like her counterparts, she also wears a bracelet.

Prior to the invasion, Ruri wore a knee-length, yellow dress with a belt over a white neck shirt, and white high-heeled shoes.

Personality
From Yūto's description, Ruri is kind and loyal to her friends, fighting for the sake of their homeland together with Yūto, her brother Shun, and her Resistance comrades. Yūto commented that Yuzu's desire to protect her friends is similar to Ruri's. Because of the invasion by Academia, Yūto stated that Ruri would never learn the summoning method used by Academia, suggesting that like Yūto and Shun, Ruri developed resentment for Fusion Summoning. She is also shown to be brave, challenging Yūri to a Duel when she was cornered by him. Like Yūya and Yūshō, she believes that Dueling isn't a tool for conflict but instead for the sake of giving people smiles and happiness. When under the influence of a Parasite Monster, Ruri's personality becomes ruthless, harsh and sadistic. It extends to the point where she enjoys inflicting pain to others as shown where she laughs in pleasure in her duels with Shun and Yūya/Yūto.

Etymology
'Ruri' is a feminine Japanese name and depending on the Kanji used, it can mean: (流理) 'flow or logic', (留莉) 'detain or jasmine', or simply 'emerald'. For this Kanji, Ruri's name means (瑠璃) 'lapis lazuli' - a gemstone that is a deep blue and is greatly prized for its unique, intense colour. In Ancient Japanese Traditions it was believed that babies who were named after gemstones were protected from harms of evil spirits. Her family name can be read by separating the two syllables apart. 黒 (Kuro) means 'black' and 咲 (Saki) means 'bloom'.

Past
Before the invasion of Heartland City, together with her older brother Shun, Ruri attended Spade Branch of Heartland Duel School. She was then introduced to her brother's best friend, Yūto, developing feelings for him since then. She and Yūto grew closer as they spent much times together, sharing their knowledge of their respective decks and the two eventually seemed to be in a relationship, having an intimate moment together. At one point during these times, together with Yūto and Shun, she watched Kaito Tenjō, the ace Duelist of Clover Branch, their rival branch, Dueling, and like everyone else was amazed by his skill. Despite their branches' rivalry, Ruri is a close friend of Sayaka Sasayama, a student from the same Clover Branch as Kaito, both often hung out and have friendly Duels. She participated in Clover Branch tournament, but lost against Sayaka. Sayaka then decided to give "Little Fairy" to Ruri because she was her most precious friend, which touched Ruri. However, Shun threw "Little Fairy" away from Ruri's hand, telling her that if she's Duelist, she shouldn't be so easily accept a card from other Duelist.undefined One day, Ruri watched Dennis Macfield performing card tricks in the park. Noticed by the performer, she was quickly picked up by "Entermage Trapeze Magician" and deposited in front of Dennis, who knelt to her in a princely manner and requested a Duel. Indirectly, Ruri was the cause of the invasion as Dennis green-lighted the invasion the moment he found her.

During the invasion, along with her older brother Shun, and her friend Yūto, Ruri joined the newly formed Resistance to fight Academia. She was seen comforting a kid with Sayaka and told them that Academia's method are wrong and Dueling isn't a tool for conflict, but should be used to bring smiles and happiness for everyone as well children's future.undefined After the first wave attack ended, at the refugee camp, she was queuing up to draw water when she met Dennis again, this time accompanied by Yūri who was hiding his face with a cloak. She was later pursued by the latter, beginning a Duel with him when she was cornered against the ruins. Ruri lost the Duel, was captured and brought back to Academia,undefined resulting in the Resistance, particularly Shun and Yūto to search frantically for her, and her close friend Sayaka, blamed herself as she witnessed her abduction.undefined

Pre-Maiami Championship
Throughout Season 1, Ruri didn't make an appearance, but instead, was briefly mentioned from time to time. Episode 21, 24 and 25 are slightly more focused on Ruri than Episode 18 where she was mentioned in Yūto's flashback.undefined

In Episode 21, Shun pays no heed to Yuzu until he noticed her face. He became surprised at the sight of her and quickly deduced that she was Ruri, bombarding Yuzu with questions on how she escaped until Yūto knocked him out telling him that she wasn't Ruri. Both were then warped away by Yuzu's bracelet.undefined

More was revealed about Ruri in Episode 24 during Yūto's and Yuzu's discussion. After begging Yūto to tell her who he was and his objective, Yūto tells her that him and Shun were trying to rescue Ruri. The discussion revealed that at first Yūto had also thought she was Ruri but then realized it wasn't the case after seeing Yuzu learn Fusion Summoning. Yūto then said he would continue fighting with Ruri and the others to create a better future as well as stating that Yuzu was a lot like Ruri, not only their faces but also their determination.undefined

The discussion on Ruri continued in Episode 25 between Reiji and Shun. Where the revelation of her capture was by Leo Akaba, Reiji's father. Reiji then figures out that Ruri is important to Shun and the rest and concludes that she still has yet to escape. It's also discovered that Shun's continous attack on LDS was to draw Reiji out and use him as a bargaining chip against Leo to release Ruri.undefined

Maiami Championship
After Yūto's and Sora's confrontation, it is presumed that Ruri was possibly turned into a card like all the other captures duelists. To save her, Sora suggested that Yūto and Shun destroy all of the Fusion users - this resulted in a Duel between him and Yūto.undefined

However, Yūri confirmed when prompted by Yuzu that Ruri was captured by him.undefined

Departure
After Shun attempted to quit the Lancers because of Reiji Akaba's announcement that they would go to the Synchro Dimension instead of Fusion Dimension, Serena assured him that the Professor must have been taking care of Ruri because he needed Serena and her counterparts.undefined

Shun vs. Dennis
During the last match of the first round of Friendship Cup, when Shun finally exposed Dennis' identity as an Academia Duelist, Dennis revealed his encounter with Ruri and how he was partly responsible for her capture since he was ordered to find her and inform Yūri, enraging Shun. undefined

Xyz Dimension Arc
While looking for Yūya's father, Yūto told Yūya that Yūshō's philosophy of bringing smile with Duel that Yūto had said before was actually something that Ruri said before she was kidnapped. Yūya and Yūto assumed that Ruri most likely learnt this philosophy from Sayaka who was Ruri's friend and a student of Yūshō.undefined

Reunion with Kaito
After Dennis lost to Kaito, he revealed that Ruri was being held captive in the Western Tower of Academia.undefined Once he arrived at Academia, Kaito immediately went ahead to the Western Tower where she was being held captive. After defeating the Keeper of the Western Tower, Diana, Ruri was surprised to see Kaito barged into the room and asked of his presence. However, Kaito only replied to her that Shun is waiting for her, surprising Ruri before she thanked him.undefined However, the moment they were outside, Ruri, who was brainwashed by Doctor, pushed Kaito off the tower.undefined

Duel Against Shun
Shun confronted Ruri in front of the Western Tower. Seeing the sight of her brother, Ruri expressed her surprised but it was quickly replaced with happiness and she rushed to hug her brother, which Shun returned. Ruri then remembered about Kaito, remembering that he came to save her but he then suddenly disappeared. The siblings' reunion was interrupted by Kaito who warned Shun that Ruri was being controlled. Ruri was oblivious of what Kaito meant, not remembering ever pushing Kaito from the tower. However, Ruri's behaviour soon changed as Doctor activated his "Parasite Fusioner", leading Ruri to attack her brother and challenged him to a Duel. Enraged at Shun for saying that she couldn't do anything without him, Ruri started her turn by summoning three "Lyrical Luscinia - Cobalt Sparrow"'s and two "Lyrical Luscinia - Sapphire Swallow"'s to Xyz Summon "Lyrical Luscinia - Assembly Nightingale". She used its effect to directly attack Shun a number of times each Battle Phase, up to the number of Xyz materials attached to it. Despite the damage he took, Shun decided not to take any Action Card, and instead accepted each of her attack as he knew vey well of her deck and her tactic, confident he could win. Seeing her brother took her attacks without any resistance, in her subconsciousness, Ruri started to regain her senses as she became horrified of what she was doing to her brother. Knowing it was not enough to completely wipe out her brother's LP, Ruri then summoned "Parasite Fusioner" from her hand and performed Fusion Summon, summoning "Lyrical Luscinia - Independent Nightingale", shocking Shun. Ruri once again used its effect to inflict direct damage to Shun, who finally resorted to use Action Card and also his monster effect to negate the damage and forced her to end her turn. Shun countered by using "Cross Xyz" to Xyz Summon "Raid Raptors - Étrange Falcon", destroying "Independent Nightingale". Ruri was about to use "Parasite Fusioner's" effect to send it to graveyard so "Independent Nightingale's" destruction would be negated, but Ruri managed to regain herself at the last minute, allowing her Fusion monster to be destroyed and told Shun to wipe out her remaining LP. She fell unconscious from the impact of the attack, prompting Shun to tend her.undefined After the duel, Ruri regained consciousness and found herself being carried down the tower stairs by Shun. She nervously called out to him when he collapsed and left him hidden near a pile of rubble. She told him to not push himself as she assured him that she would bring back Kaito and ran off to search for him.undefined

Duel against Yūya and Yūto with Serena
However, she wondered what path to take inside Academia before something told her to go right. She ran into Yūya and they both were about to go help Shun, but she suddenly challenged him to a Duel, returning to her brainwashed state. Upon seeing Yūya set three cards without summoning a monster, she recognized that strategy. She was surprised when Yūya revealed he was Yūto after hearing the same words she told Yūto. She Special Summoned "Lyrical Luscinia - Turquoise Warbler" and used the effect of "Turquoise Warbler" to Special Summon "Lyrical Luscinia - Sapphire Swallow" and overlays them to bring out "Assembly Nightingale", which gained 100 ATK for each Overlay Unit. She believed Yūya was Yūto due to him being familiar with her Deck, but didn't know about "Parasite Discharge", which let her Special Summon "Parasite Fusioner" from her hand or Deck. She then used the effect of "Parasite Fusioner" to Fusion Summon "Independent Nightingale" and equip "Parasite Fusioner" to it. Ruri used the effect of "Independent Nightingale" to inflict damage to Yūya for each level it has. She then attacked him directly but Yūya activated two "Phantom Knights Lost Vambrace" to prevent Phantom Knights he control from being destroyed and lower "Independent Nightingale's" ATK. She was surprised when they were able to Xyz Summon and weaken her monster during her turn. She then teamed up with Serena, who joined the Duel after tasing Shun, and let her use "Assembly Nightingale" to Fusion Summon "Parasite Queen". When Serena revealed that Yuzu has a Parasite Monster in her head to Yūya, Ruri also told that they have been reborn by Doctor. However, she was surprised when Yūto took over Yūya's body.undefined

Deck
Ruri uses a "Lyrical Luscinia" Deck. Her Deck focuses on swarming the field with a tremendous number of "Lyrical Luscinia" monsters to Xyz Summon "Lyrical Luscinia - Assembly Nightingale", which can inflict more damage and is harder to destroy with more Overlay Units. Via the "Parasite Fusioner" that she received, she can also Fusion Summon "Lyrical Luscinia - Independent Nightingale", which also capitalizes on the number of Overlay Units attached to "Assembly Nightingale".

Trivia
