She first appears when she goes to Masquerade's "party", and are transported to Vestroia, falling under the control of Naga as he uses Silent Core energy. Then, she faces off against Dan, but loses and leaves thinking that Dan did well but that she has a secret weapon. She faces Dan, Runo and Marucho alongside Julio and Klaus. They lose when Marucho activates the Fire, Water, Light Triple Node and Runo's Cut-in-Saber ability card, making Drago evolve. They are then freed from Naga's control. Along with the others Masquerade sends her Fortress to the Doom Dimension but it is later returned to her.
She then stalls Centorrior when the Battle Brawlers are in Vestroia.
She develops a crush on Joe and saves him from Hal-G using her Martial Arts (Dan and Julie also made fun of Chan saying that Chan and Joe were dating). At the end of the series, they are seen dating in the bench in the background while Runo and Dan were on a date.
She is currently ranked 5th.
