Past
Like other Duelists in the Fusion Dimension, Asuka was sent to Academia to be trained as Duel soldier once she graduated from her elementary school. However, a year ago, her friend, who was sent to the Xyz Dimension, revealed that they also carded people who are not Duelits like it was a hunting game. Her friend begged her to leave Academia with her, not wanting Asuka to do such a thing and bear the same pain as her. Asuka at first reluctantly agreed and secretly intended to persuade her that what Academia was doing was the right thing, but when they reached the harbor, they were intercepted by Juvenile Officers who then turned her friend into card, horrifying Asuka.

Before she could share the same fate, She was saved by Yūshō who helped her hiding from Academia and taught her his philosophy to bring smiles through Dueling. Both then formed You Show Duel School to shelter other former Academia students who'd decided to escape. Since then, she polished her skills with other students everyday to spread Yūshō's teaching and continue to help other former Academia Duelists who are running away, making her infamous among the Juvenille Officers.

Duel Against Juvenile Officers
Asuka posed as a gondolier, looking around the town until she heard the commotion. Following the commotion, Asuka spotted Yuzu cornered by the Juvenile Officers and decided to save her. She told Yuzu to stand back while she Duelled them. Asuka easily defeated all three of them with her Ritual Monster, "Cyber Angel - Vishnu", and took Yuzu to You Show School, where revealed that all Duelists who escaped from Academia are hiding there and she then brought her to Yūshō.

ARC Area Project
Asuka explained to Yuzu about Academia's goal to united all dimensions and created utopia, and that plan was referred as "ARC Area Project". However, Asuka revealed that in reality, the project was actually to cover up Reo's plan to conquer all four dimensions. She then told her how she decided to escape from Academia with her friend who opposed of Academia's plan, saved by Yūshō, and how she and Yūshō built You Show Duel school to teach others of Yūshō's philosophy, revealing that the other students at the school were formerly Academia students who had gone to the Xyz Dimension and her the same scar as her friend. Understanding Asuka's pain and resolve, Yuzu told Asuka that she will help her.

Yuzu's Reunion with Yūgo
They were interrupted by some students who told them they were attacked while protecting another Academia student who escaped and the rest of their friends were still Dueling the Academia Duelist. Unfortunately, by the time they arrived, the Academia Duelist, Yūri, has already defeated all five students and carded them. Before Yūri could attack, Yūgo arrived, activating Yuzu's bracelet that transported Yūri away, shocking Asuka. She was then bewildered by the antics between Yūgo and Yuzu who were finally reunited.

Yūshō vs. Dennis
Asuka returned to You Show Duel School with Yuzu and Yūgo and she told Yūshō that it was time to battle Academia. Yūshō agreed and he announced his intention to accompany them, though Asuka didn't want Yūshō to push himself. However Dennis Macfield showed up with a squad of soldiers to capture Yuzu, and Asuka was surprised when Dennis revealed he was one of Yūshō's students. She asked him how he found them and Dennis explained that he had used eyewitness reports to track them down. He challenged Yūshō to a Duel, and Asuka was surprised when Yūshō merely set a card for his first turn. However the Trap Card, "Miracle Silk Hat" distracted Dennis long enough for Asuka to help Yūshō escape underground.

Kaito vs. Dennis
Asuka and Yūshō boarded a ship to Academia, and Yūshō wanted Asuka to disembark so he could face Reo alone. Dennis caught up with them and Asuka challenged him to a Duel. Dennis refused, as he wanted to defeat Yūshō, however, Kaito, another of Yūshō's former students, arrived to Duel Dennis instead. Before the Duel, Asuka asked Yūshō if it was okay for Kaito to Duel Dennis. After Kaito defeated Dennis, she watched everyone applaud both Duelists for their Duel. Dennis revealed the locations of Ruri and Rin in the Eastern and Western Towers of Academia, and Asuka watched in shock as he sealed himself into a card.

Arriving at Avademia
Asuka arrived at Academia with Yūshō and Kaito, wondering if they were in a trap when there were no Academia soldiers waiting for them. When Yūgo appeared before them, Asuka wondered how did he arrived before they did and learned that Yuzu's bracelet sent him. She told Yūgo they were at Academia and they know where Rin is. She told him that Rin is at the Eastern Tower and prepared to go see Reo with Yūshō.
