She is the only female member of the Gouha Six. Yuka uses a Baseball Deck largely composed of FIRE Attribute Warrior Type monsters that are baseball-themed parodies of Yuuma Tsukumo's "Onomat" monsters, and her ace monsters, "Player #39: Home Run Hitter" and "Player #99: Grand Slam Dragon", being based on Yuuma's and Astral's own aces, "Number 39: Utopia" and "Number 99: Utopic Dragon".
