Lulu Obsidian, known as Ruri Kurosaki (
Lulu is from Heartland City in the Xyz Dimension along with her older brother Shay Obsidian and her close friend Yuto. After the invasion by Duel Academy, she and other survivors formed the Resistance in retaliation before she was captured by Yuri. Despite being the first of Zuzu's counterparts to be mentioned, Lulu appears on-screen after Celina and even Rin. According to Leo Akaba, Lulu is crucial to his plans.
Her physical body perished when she reunited with her counterparts, with her spirit ultimately living on in Zuzu.

Lulu's face resembles those of her counterparts. She has pink eyes, long dark purple hair which extends past her lower back even when tied up in a bow-shaped style and has shorter, lilac side tails. She secures her hair with a wing-shaped barrette and, after the invasion, dons large, feather earrings. Lulu is the only one of her counterparts with longer hair and side tails. Like her counterparts, she also wears a bracelet.
Before the invasion of the Xyz Dimension, Lulu dressed simply in a yellow and white, knee-length dress with white shoes. After the establishment of the Resistance, however, she wears more practical clothing; a cream vest with an under dress that splits into three, worn out pants, brown boots, two brown belts, and a red sash that evokes Yuto and Shay's scarves on her right hip.
Lulu has a very feminine and graceful mannerism, being polite and gentle towards others. This is in contrast to her counterparts, who all display tsundere or rude behaviors. In contrast to Rin, for example, who violently attacks Yugo after he saved her, Lulu simply smiles and thanks Kite for helping her. Similar to Zuzu who has feelings for Yuya, Lulu has feelings for Yuto, to which he returns.
According to Yuto, Lulu is kind and loyal to her friends, fighting for the sake of their homeland together with their Resistance comrades. Yuto commented that Zuzu's desire to protect her friends is similar to Lulu's. Due to the invasion of Duel Academy, Yuto stated that Lulu would never learn the Fusion Summon with a smile, suggesting that like Yuto and Shay, Lulu developed resentment for Fusion Summoning. She is also shown to be brave and confident, challenging Yuri to a Duel when she was cornered by him. Like Yuya Sakaki, Yusho Sakaki and Yuto, she believes that Dueling is not a tool for conflicts but instead for the sake of making people happy and smile; Lulu learned this belief from Saya Sasayama, who herself learned it from Yusho Sakaki himself. However, despite the hatred of Fusion Dimension she might have developed, Lulu pays little to no attention to her Duel Academy's Duel Disk.
When under the influence of a Parasite Monster, Lulu'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 Shay and Yuya/Yuto.
"Ruri" is a feminine Japanese name and, with the Kanji used 「瑠璃」, means "lapis lazuli", a gemstone that is a deep blue and is greatly prized for its unique, intense color. Ancient traditions in Japan believed that babies who were named after gemstones were protected from harms of evil spirits. Additionally, the kanji of her name is also part of several bird species such as the Siberian blue robin 「小瑠璃」 (Koruri) and the Blue-and-white flycatcher 「大瑠璃」 (Ōruri). Her family name can be read by separating the two syllables apart. 「黒」 (Kuro) means "black" and 「咲」 (Saki) means "bloom".
Her international name rhymes with "Zuzu", one of the three girls she resembles, which means "pearl", "calm", "peaceful", or "protected" - the former reflecting to her Japanese name and the middle ones her gentle personality. It is also commonly used as a pet name. Her last name, "Obsidian", refers to a black, volcanic glass. Incidentally, the name Lulu may also be played on the word "lull" or "lullaby", linking her with her songbirds Deck theme, as well as being an abbreviation of it (Lyrilusc). It is also possible that she is named after pop singer Lulu Kennedy-Cairns, similar to Zuzu being named after Susan Boyle.
Lulu was not born naturally, but created when Ray Akaba defeated Z-ARC with the Four Nature Cards and divided both herself and Z-ARC in addition to the Original Dimension. Ray intended for her fragments to prevent Z-ARC's fragments from reuniting and attempting to destroy the world, and she ensured her fragments were reincarnated in close proximity to Z-ARC's fragments within their appropriate Dimension; Lulu was placed in Heartland City in the Xyz Dimension as the sister of Shay Obsidian, a friend of Z-ARC's Xyz Dimension fragment Yuto. The card "En Birds" was transformed into a bracelet. Lulu attended the Spade Branch of Heartland Duel School, known for training professional Duelists. After one of her duels, Shay introduced Lulu to Yuto which resulted in the two beginning to spend more time with each other and grow closer. At one point she, Yuto, and Shay watched a Duel of Kite Tenjo, the ace of the Clover Branch. Lulu was friends with Saya Sasayama, a student of the Clover Branch. She once lost to Saya in a Duel, and Saya offered her a "Little Fairy" card afterwards. Lulu was surprised that Saya was giving her one of her ace cards, but the conversation was interrupted by Shay, who was furious that Lulu had accepted a card from another Duelist as he took such actions seriously, and he slapped the card out of her hands.
Lulu watched Dennis McField performing card tricks in the park. Noticed by the performer, she was quickly picked up by "Performage Trapeze Magician" and deposited in front of Dennis, who knelt to her in a princely manner and requested a Duel. Indirectly, Lulu was the cause of the invasion as Dennis green-lit the invasion the moment he found her. During the invasion, Yuto overheard her comforting a young girl, claiming that Dueling is not a tool for conflicts but instead for bringing smiles and happiness for everyone, even the kids' future. She had picked this up from Saya herself, who in turn had heard it from a teacher at her school, Yusho Sakaki.
After the invasion, Lulu was queuing up to draw water when she met Dennis again, this time accompanied by Yuri. She was pursued by Yuri, beginning a Duel with him when she was cornered against the ruins. Lulu lost the Duel and was captured and brought back to Duel Academy,  with Saya watching in horror, fear preventing her from intervening. Yuto, Shay and other Resistance members later searched for her frantically. After the former's encounter against Yugo ended, Shay asked Yuto about the whereabouts of Lulu. Yuto shook his head in response, prompting Shay to curse. Shortly after her capture, Lulu was brainwashed by The Doktor.
Pre-Arc League Championship
Lulu was indirectly mentioned by Yuto when he was Dueling Sylvio Sawatari. Yuto told a confused Zuzu Boyle that he didn't want her to get hurt again, thinking that she was Lulu. Although Shay initially paid no heed to Zuzu, once he noticed her, he mistook her for Lulu and asked if she had escaped with her own strength, much to Zuzu's confusion. Yuto insisted that Zuzu wasn't Lulu and knocked Shay unconscious before Zuzu's bracelet teleported them away. Later on, Yuto and Zuzu met up again. She asked Yuto if Lulu resembled her, and Yuto answered that he thought she was Shay's sister at first.
Arc League Championship
When Yuto asked Sora Perse about Lulu's whereabouts, Sora suggested that she might be sealed into a card like the other people who were captured by Duel Academy. However, Yuri confirmed when prompted by Zuzu that he captured Lulu.
After Shay attempted to quit the Lancers because of Declan Akaba's announcement that they would go to the Synchro Dimension, Celina assured him that the Professor must have been taking care of Lulu because he needed Celina and her counterparts. Lulu was mentioned again by Dennis during his Duel with Shay, who explained the short history between him, Yuri and Lulu. After learning that Dennis helped in Lulu's capture, Shay attacked him, but was prevented from doing so.
After Kite defeated Dennis he told him that Lulu was held captive in the Western Tower of Duel Academy. After Kite defeated Diana, he broke down the door to Lulu's room. Lulu was surprised to see Kite, who told her that Shay was waiting for her, and she happily thanked him. However as soon as they left the tower room, Lulu pushed Kite off the edge and watched him fall with an evil smile.
Shay soon arrived, and Lulu pretended to act normally in front of him by curiously examining the unconscious Diana's body. She hugged him and asked about Kite, claiming that she didn't remember what had happened to him. Kite returned and attempted to tell Shay about her brainwashing. Although Shay initially denied it, the evidence that Kite provided proved to undeniable, and Lulu revealed her brainwashing. She tried to attack Shay, though he fended her off easily, so Lulu then challenged her brother to a Duel. She quickly Xyz Summoned "Lyrilusc - Assembled Nightingale" and viciously assaulted him using her usual tactics. Shay claimed that he didn't care who won the Duel and he asked her why she was attacking him when he was all that she had left, and Lulu stated that she wasn't anybody's belonging, but the exchange had caused her true subconscious to begin to wake up. Shay brought out "Raidraptor - Blaze Falcon" on his next turn, and reduced the Overlay Units of "Assembled Nightingale", claiming that he knew Lulu's Deck and she warned him to remember those words.
She drew "Fusion Parasite" and attacked Shay again as her true personality began to recognize him, then Special Summoned "Fusion Parasite" and Fusion Summoned "Lyrilusc - Independent Nightingale". Shay blocked Lulu's efforts to defeat him and she mocked him for acting so tenaciously despite claiming not to care whether he lost or not. Lulu was shocked when Shay Summoned Saya's "Little Fairy" and used "Cross Xyz" to Cross Xyz Summon "Raidraptor - Stranger Falcon". Shay told her that Saya, Kite, and all of their comrades were waiting for her return, but Lulu claimed not to care. As Shay used the effect of "Stranger Falcon" to destroy "Independent Nightingale" and inflict damage, Lulu tried to use the effect of "Fusion Parasite" to prevent its destruction but the real Lulu, in her own subconscious, stopped the Parasite. Lulu managed to regain control and told Shay to attack her, and "Stranger Falcon" wiped her out.
After the Duel, Lulu regained consciousness and found herself being carried down the tower stairs by Shay. Weakened by their Duel, Shay collapsed, and Lulu left him hidden near a pile of rubble. She told him to not push himself and she assured him that she would bring back Kite and ran off to search for him. As she wondered what path to take inside Duel Academy, something told her to go right. She ran into Yuya Sakaki, initially mistaking him for Yuto until he clarified his identity and they introduced themselves to one another. Lulu tried to take Yuya to Shay, but she returned to her brainwashed state and suddenly challenged Yuya to a Duel. Upon seeing Yuya Set three cards without Summoning a monster, she recognized the strategy and she was shocked when Yuya claimed that he was Yuto. She Xyz Summoned "Assembled Nightingale", and she noted Yuya's apparent familiarity with her Deck.
Informing Yuya that he didn't know everything, she used the effect of "Fusion Parasite" to Fusion Summon "Independent Nightingale" and equip "Fusion Parasite" to it. Lulu used the effect of "Independent Nightingale" to inflict damage to Yuya and then attacked him directly but Yuya activated two copies of "The Phantom Knights of Lost Vambrace" to protect his LP and weaken "Independent Nightingale", and to her shock and anger they Xyz Summoned "The Phantom Knights of Cursed Javelin" and weakened her monster during her turn. Shay then arrived, informing Yuya about the extent of Lulu's brainwashing and tried to go after the Doktor, but Celina tased Shay and joined the Duel. Lulu allowed her to use "Independent Nightingale" to Fusion Summon "Parasite Queen". Celina revealed to Yuya that they and Zuzu had Parasite Monsters in their heads, and Lulu also claimed that they had been reborn by the Doktor. However, she was surprised when Yuto took over Yuya's body and used a Rank-Up Xyz Evolution to call out "Dark Rebellion Xyz Dragon". Yuto traded blows with Lulu and Celina using "Dark Rebellion" and Action Cards, while Lulu and Celina took turns controlling "Parasite Queen". Yuto eventually reverted back to Yuya, but the girls had spotted a Parasite Monster entering Yuya's ear. They believed that it had taken control of him, but to their shock Yuya remained unaffected and he reacted in rage. Despite Yuya and Yuto managing to remove their "Fusion Parasites" from the field, the girls managed to revive all of them and treated them as double the number to power up "Parasite Queen". Lulu told Yuya that it was a waste of time removing all of them earlier. She and Celina noticed that something was wrong when the "Fusion Parasites" began to react in fear, and they were surprised to see a dark aura coming from Yuya as he Xyz Summoned "Odd-Eyes Raging Dragon". Yuya used the effect of "Raging Dragon" to destroy all the cards, though they believed that "Parasite Generator" and "Parasite Factory" would protect their cards. However, "Raging Dragon" negated the effects of Spell and Trap Cards, and could also attack twice per turn, defeating Celina and Lulu at the same time. Despite the impact, Lulu swiftly recovered from her injuries and she escaped with Celina and returned to the Doktor. She left with him and her counterparts after the Doktor trapped Yuya in the lab.
Lulu was summoned to the Professor's inner chambers in a capsule with her counterparts and she was freed from the Doktor's control when the Professor sealed him into a card. She was angry that she had been trapped again and she learned of her origins when the Professor recounted how his daughter Ray and the Original Dimension had been divided after she defeated Z-ARC using four cards. To Lulu's shock, the Professor revealed that he planned to unite Lulu and her counterparts back into Ray using the ARC-V Reactor.
Yuya then arrived, and the Professor had Lulu and the other girls' capsules moved nearer to the ARC-V Reactor to begin the process of reuniting them and the dimension. Yuya and Declan Akaba challenged the Professor to a Duel, and Lulu quickly realized that Yuto was present within Yuya when he declared that he couldn't forgive Leo for his plans. Lulu was surprised at Declan's capability to Fusion, Synchro, and Xyz Summon in one turn. She was relieved to realize that Yuto still remembered their promise to make people smile with Dueling despite the situation. Her capsule started to glow as the ARC-V Reactor continued to progress, and she begged Yuto to save them. To Lulu's surprise, Leo revealed that Yuya and Yuto were fragments of Z-ARC as Lulu and the other girls were of Ray. To save them, Yuya Fusion Summoned "Performapal Gatlinghoul", inflicting significant damage to Leo and preparing to finish him off with its second effect of "Gatlinghoul"; as he did, Lulu noted the statistics in play.
Lulu later sensed Yuto making contact with Declan. Lulu was overjoyed when Yuya Xyz Summoned "Dark Rebellion Xyz Dragon", believing it proof that Yuto really was inside Yuya. Leo believed that Yuya was already Z-ARC, but Lulu believed he and Yuto were still there. She and her counterparts were surprised to see a dragon's silhouette form from Yuya's dark aura, but they continued to believe in them and they began to pray, calming Yuya and Yuto down. But the ARC-V Reactor continued to power up, causing Lulu's capsule to glow brighter and her hand began to disappear. Lulu's scream prompted Yuya and Yuto to Awaken again to rescue her, though fortunately Yusho Sakaki restrained Yuya, and he informed the girls that he believed that they were fragments of Ray and that Yuya and Yuto were fragments of Z-ARC. Yusho left to stop Yugo and Yuri from Dueling, and once he left, Leo continued the process of the ARC-V Reactor. Lulu and her counterparts passed out when the ARC-V Reactor's energy input increased to fifty percent. While they were unconscious, purple energy passed from Lulu and her counterparts' bodies into Riley Akaba. She shed tears while she was unconscious and was transferred into the ARC-V Reactor when Leo ordered it to be accelerated after seeing Yuri absorb Yugo.
Following the battle with Z-ARC, Lulu's fate was unknown but Declan theorized that she was most likely still inside the remnants of the ARC-V Reactor. Leo managed to collect what appeared to be Ray's spirit, though he was unsure that it was Ray and theorized that Ray's fragments would eventually revive as Zuzu. However, Shay denied that Lulu was gone after witnessing Yuto's presence in Yuya. After Yuya defeated Declan, Lulu's spirit revived within Zuzu when Ray reacted to their Duel.
Shay is Lulu's older brother. Despite an at times rocky relationship regarding Lulu's Dueling skills, the siblings apparently share a very close bond, as Shay was willing to do anything to get Lulu back, including forming an alliance with Declan, whom he did not trust. The reason Shay went to Standard was to find ways to get Leo Akaba give his sister back. Shay was enraged to find out Dennis' betrayal and significance in his sister's disappearance, and dedicated one of his final attacks to her during the exposure and rematch with Dennis.
Lulu appears to love her brother dearly; she was horrified when the Parasite Monster that had possessed her attacked him. Lulu was so determined to stop the Parasite that she was able to briefly break free of its control and cause it to miss the activation timing of "Fusion Parasite".
Lulu first met Yuto through Shay and they took an instant liking towards each other. They began growing very close to each other and learning about the other's decks and tactics. Yuto deeply cherishes Lulu, as he followed Shay to help with Lulu's situation, and protected Zuzu when he initially thought she was Lulu. He even went to Sora and personally demanded him about Lulu's whereabouts. Lulu is the one who taught Yuto to believe in Duels bringing smiles, in the Sakaki father-son's Dueling style and philosophy. This demonstrates their strong bond as he repeated his own version of her message to Yuya in his final moments in physical form. When Yuya faced Leo, Lulu was able to sense Yuto within Yuya and was touched by his support for her as well. They also voiced their concern for each other during the Duel. She was happy when Yuya summoned "Dark Rebellion Xyz Dragon", proving to her that Yuto was indeed present and within Yuya. When the Professor claimed that Z-ARC had already taken control of them, Lulu protested that she would believe in Yuto.
Lulu and Yuto are also the only counterparts to share romantic feelings for each other since they met in their teen years. The bond between them was so strong that Yuto was able to physically take over Yuya's body in his Duel with Lulu.
Kite is her older brother Shay's respected rival. As Yuto and Shay have battled Kite countless times before the invasion, Kite and Lulu are presumably well acquainted. Lulu even went to one of Kite's Duels and supported him. Like Kite, Lulu is a disciple of Yusho Sakaki's Dueling style and philosophy of bringing smiles with Duels. In Shay's place, Kite traveled to the Fusion Dimension to rescue Lulu. After reaching her in the Western Tower, Lulu smiles kindly to him and thanks him.
Lulu is shown to be good friends with Saya, and the two often hung out with each other before the invasion. During the invasion, it is revealed that Yuto's statement of "Duels with smiles" - the ideal of Yusho Sakaki, was inherited from Lulu, and Lulu herself inherited this from Saya, a student of Yusho's.
To Lulu, Dennis was a friend. However, Dennis was a member of Duel Academy who came to find Lulu and pinpoint her location to Yuri, effectively betraying her and playing major role in her subsequent capture. It is unknown if Lulu knows of Dennis's role in her kidnapping, or Dennis's identity as a spy.
Lulu uses a "Lyrilusc" Deck. Her Deck incorporates Level 1 monsters with either 0 or 100 ATK or DEF, which focuses on swarming the field with "Lyrilusc" monsters to Xyz Summon "Lyrilusc - Assembled Nightingale". The more Overlay Units it has, it can inflict more damage, become harder to destroy and prevent battle damage. Like her brother, she also has multiple copies of several monsters, such as "Lyrilusc - Cobalt Sparrow" and "Lyrilusc - Sapphire Swallow", whose effects enable her to Summon five monsters swiftly.
Via the "Fusion Parasite" that she received when brainwashed by the Doktor, she can also Fusion Summon "Lyrilusc - Independent Nightingale", which capitalizes on the number of Overlay Units attached to "Assembled Nightingale" and is capable of inflicting heavy burn damage in addition to its high attack. Lulu also utilizes several "Parasite" cards to support her "Fusion Parasite".
