Sylvia participates in the Royal Tennis Academy in Junior Class located at the Mushroom Kingdom. He tennis doubles partner is Sasha, and holds the second rank in the Junior Class singles. Due to the bright sun, her face would squint and wince, as she couldn't see where the ball goes sometimes, causing her to remain the same class for a year or two. She is also held back due to Sasha's lack of interest in leaving junior class and fickle attitude towards practice.
