Emi participates in Royal Tennis Academy in Senior and Varsity Class located at the Mushroom Kingdom. Her tennis doubles partner in Senior Class is Roy, and her tennis doubles partner is Flit. She holds the first rank in Senior singles and doubles, and gets a little annoyed when losing a game, but recovers from little trouble, and states the intent to get back at her conqueror(s). She is encouraging, and easygoing, as she doesn't let anything bad get to her.
