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 Reo Akaba. Despite being the first counterpart to be mentioned, Serena and Rin have both appeared on-screen before Ruri.

Appearance
Ruri has purplish-black hair that reaches her lowerback, with lilac sidetails. Her eyes are violet or pink (the exact color is difficult to say as the only time they were visible it was night).

Etymology
Ruri's name means 'Lapis Lazuli' - a stone that is a deep blue and is greatly prized for its unique intense colour. It also means 'Emerald'. Her family name can be read by separating the two syllables apart. 'Kuro' means 'Black' and 'Saki' means 'Bloom'.

Past
During the pre-invasion of Heartland, Ruri watched Dennis Macfield 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, Ruri was the cause of the invasion as Dennis green-lighted the invasion the moment he found her.

After the invasion, Ruri was queuing up to draw water when she met Dennis again, this time accompanied by Yuri. She would later end up being pursued by the latter, beginning a Duel with him when she was cornered against the ruins. Ruri lost the Duel and was captured and brought back to Duel Academy.

Yuto and her older brother Shay would later end up searching for her frantically. After the former's encounter againstYugo ended, Shay asked Yuto about the whereabouts of Ruri. Yuto shook his head in response, prompting Shay to curse.

Xyz Arc
Throughout Season 1, Ruri did not make an appearance, but instead, 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.

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. After bombarding Yuzu with questions on how she escaped, Yūto knocked him out telling him that she wasn't Ruri. Both were then warped away by Yuzu's bracelet.

More was reveled 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 use Fusions. 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.

The discussion on Ruri continued in Episode 25 between Reiji and Shun. Where the revelation of her capture was by Reo 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 is also discovered that Shun's continous attack on LDS was to draw Reiji out and use him as a bargaining chip against Reō to release Ruri.

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

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

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