Arc League Championship
Olga defeated Haruno Mihara on the seventh day of the Arc League Championship, during the second round, securing her place in the Top 16. On the day of the third round, Olga and the other contestants were informed that the third round would be a city-wide Battle Royal, with participation determined by the Pendulum Monsters that the contestants found.
Olga lured Gong Strong further into the Iceberg Area after seeing Gong get his second Pendulum Monster, and he challenged her to a Duel. The Duel went fairly evenly until they were interrupted when Zuzu crashed into her. Olga was angry at Zuzu for the intrusion. The Duel turned into a Battle Royal, with Zuzu paired with Gong, and Olga paired with Halil. Olga proceeded to Summon her ace card, "Glacial Beast - Iceberg Narwhal", but she and Halil were defeated by Zuzu's "Bloom Diva the Melodious Choir".
After their Duel with Zuzu and Gong, Olga and Halil walked through the Jungle Area. They encountered Trout and Reed Pepper and challenged Reed to a Duel. Even though Olga Summoned her ace monster, Reed activated the effects of his "Royal Cookpals" to destroy his opponents' monsters, then used "Metabolic Storm" to inflict damage to them equal to the ATK of the destroyed monsters. As per the ante rules, Trout took the Pendulum cards that Olga and Halil wagered, much to their disgust, as Trout hadn't even Dueled.
Later, Olga and Halil slid down an ice board on the Ice Field, nearly crashing into Yuri and Dennis McField. The LID pair mistook Yuri for a Battle Royal participant and challenged him to a Duel. Yuri was irritated by their intrusion, but he accepted anyway. He defeated Olga and Halil and sealed them into cards, which he gave to Zuzu.
After Z-ARC's defeat and the Standard Dimension's transformation into the "Pendulum Dimension", Olga was freed from her card. She was later seen watching Yuya Sakaki's Duel against Jack Atlas with Halil and applauded when Yuya won. She then watched Yuya and Declan's Action Duel She was happy when Yuya won the Duel and witnessed Zuzu's revival.
Olga uses an Glacial Beast Deck focused around Synchro Summoning her ace monster, "Glacial Beast - Iceberg Narwhal", which prevents her opponents from using Spells and Traps when it attacks, while also being able to double any effect damage her opponents take.
