Changes

Sukai learned that [[Yudias Velgear|Yudias]], [[Yuhi Ohdo|Yuhi]] and [[Yuamu Ohdo]] were searching for them, and they followed them back to the [[UTS officeMain Office]]. To keep the [[UTS]] employees from finding them, Sukai "haunted" Yuhi and warned him not to return underground while ordering him to remove reflections. Eventually Yuamu decided to return underground anyway, and Sukai pursued her, Yudias and Yuhi, fruitlessly attempting to stop them. After Yuamu and Yudias entered a dark building, Yudias attempted to light the darkness with his eye beams, so Sukai attacked his eyes to force Yudias back into his human form. Unfortunately for Sukai, they had been tricked into entering a reflective room where they couldn't hide, and they were forced to coalesce into their human form and reveal their true identity to the UTS employees.<ref name="ep16">{{episode|Yu-Gi-Oh! GO RUSH!!|16|ref}}</ref> Yuamu explained she was looking for [[Yuna Goha]] and challenged Sukai to a [[Yu-Gi-Oh! Rush Duel|Rush Duel]] for the information they had, and though Sukai believed she had no information to offer them given their extensive research on UTS, they accepted the Duel. Aware of Yuamu's [[LIGHT]] [[High Tech Dragon]] monsters, Sukai countered Yuamu's tactics with anti-LIGHT cards and strengthened their monsters to make them immune to the effect of Yuamu's "[[Blue Tooth Burst Dragon (anime)|Blue Tooth Burst Dragon]]", before severely reducing the ATK of her monsters by the number of LIGHT monsters in Yuamu's [[Graveyard]] with "[[Golondrinas Jail]]". Yuamu was able to survive Sukai's attacks, but Sukai believed she would be unable to defeat them with her current Deck. To their surprise, Yuamu began discarding cards that didn't suit her Deck, and she admitted she'd snuck a freshly opened booster pack into her Deck while the reflective room had been darkened to throw off Sukai's predictions. Sukai believed the strategy would be ineffective, but Yuamu drew and Summoned "[[Red Boot Boost Dragon (anime)|Red Boot Boost Dragon]]", whose [[DARK]] [[Attribute]] and effect to return monsters from Yuamu's Graveyard to her Deck completely countered Sukai's strategy, and Yuamu defeated them.<ref name="ep17" />

Sukai admitted afterwards they didn't know anything about Yuna, but that this likely meant she was at the [[Rovian Bandits]]' [[Badloon Castle]], which could only be entered by attaining the Macho Rank. They suggested Yuamu, Yuhi and Yudias could raise their rank by Dueling at the [[Coruffium]].<ref name="ep17" /> Sukai took the three of them to the Coruffium and bade them farewell, but as they were flying through the streets of the Alien Residential Area, they were captured with a vacuum cleaner by Yuna Goha herself.<ref name="ep18">{{episode|Yu-Gi-Oh! GO RUSH!!|18|ref}}</ref> Yuna trapped Sukai's skyfish in a plastic bag and took them with her to the Coruffium to meet Yuamu, Yuhi and Yudias, abusing Sukai every time they tried to divulge her identity. Sukai was forced to watch as Yuna Rush Dueled Yudias for his and the Ohdo twins' Duel Power, and eventually confirmed her identity after she revealed it in frustration due to Yudias believing her to be the person who gave her his [[Duel Disk]]. After Yuna defeated Yudias, she took Sukai with her.<ref name="ep20">{{episode|Yu-Gi-Oh! GO RUSH!!|20|ref}}</ref>
