Olga

Olga is a character in the Yu-Gi-Oh! ARC-V anime. She is an exchange student from the LDS Synchro Summoning course.

Present
Olga was present at the opening ceremony for the Junior Youth Battle Royal. She later challenged Noboru Gongenzaka to a Duel in the Iceberg Area. During the Duel, Yuzu Hīragi crashed into her with Halil following after, turning their Duel into a Battle Royal. Olga and Halil worked together to defeat Gongenzaka, leaving Yuzu remaining. However, Yuzu used the effect of her "Bloom Diva the Melodious Muse" to One Turn Kill the pair.

Olga and Halil eventually make it to the Jungle Area. There, Halil spies two Pendulum Cards. As he starts to grab them, they fly away, causing the pair to chase after them. They are confronted by Michio Mokota and Teppei Tairyobata. Michio Duels and defeats them, taking their remaining Pendulum Cards.

Later, Olga and Halil are seen sliding down a cliff just as Yūri arrives in the Standard Dimension. Believing him to be a Junior Youth competitor, they challenge him to a Duel and lose. Yūri turns them into cards afterwards.
