Lily, known as Yuri Yamamoto in the Japanese version, is a character appearing in the Tag Force series.
In Tag Force 1 she appears as an Obelisk Blue student. In Parts 2 and 3 of the game she is partnered with Andrea, who also uses a Dinosaur Deck just like her.
In later GX Tag Force installments, her Deck's focus is shifted to the instant win effect of "Destiny Board".
