*Lulu Obsidian, known as Ruri Kurosaki in the Japanese version, is a character in the Yu-Gi-Oh! ARC-V anime. She is a reincarnation of Ray Akaba, as well as a dimensional counterpart of Zuzu Boyle (Standard Dimension), Celina (Fusion Dimension) and Rin (Synchro Dimension).

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.

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. 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 to 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.*
