Anca, known as Yuki Kato in the Japanese version, is a character appearing in the Yu-Gi-Oh! GX Tag Force series.
In Yu-Gi-Oh! GX Tag Force Evolution, if the player loses to her, she suggests that he treat her to lunch, although she won't accept his sandwiches.
In Yu-Gi-Oh! GX Tag Force, if the player gets her Deck Recipe, they also get the card "Enchanted Javelin".
In Yu-Gi-Oh! 5D's Tag Force 4, Anca can be found in the City.
In Tag Force Anca plays a "Warrior Recruit" Deck, which also includes cards that shut down the opponent's Spell and Trap Cards, like "Jinzo" and "Silent Swordsman LV5".
In Tag Force 4, Anca plays a Deck based on "Royal Oppression" and removing cards from play.
In Tag Force 5, Anca uses a Deck called "Drawing Song on G String" (Ｇ線上のえかきうた, G Senjō no Ekaki-uta).
