Yu-Gi-Oh! Duel Monsters GX

Asuka is the best female duelist in Duel Academy. She has a very keen eye for details and reads everyone one of her opponents moves. She forces her opponents to play their best cards, that way making her victory much more satisfying. She is shown to have some sort of interest (and possible attraction) toward Judai.

Being the smartest at the academy of all the girls, Asuka has many boys who find her attractive; however, Asuka's personality is more geared toward the game than love.

In the anime, Asuka plays a "Cyber Girl" deck while in the manga she plays an "Ice" deck.

Yu-Gi-Oh! Arc-V

Asuka in this series is an alternative version of the same character in GX. She is a former student of Duel Academy in Fusion Dimension who escaped from the island and co-founded You Show Duel School with Yusho Sakaki in XYZ Dimension.
