Nina

From the Super Mario Wiki

Nina (Japanese: ニーナ Nīna) is a playable story mode character in the Game Boy Color version of Mario Tennis. She is clad entirely in orange, the color of her hair, eyes, tank top/mini-skirt, shoes, and racket.

In Mario Power Tennis, she is a coach at the Academy. She enjoys teasing Alex. She comes in with Alex to congratulate Max or Tina after beating Master Level on the Wall Practice and Tennis Machine minigames, during which she says something that gets on Alex's nerves. Other than that, she plays a small role in the game, just keeping an eye on the Swift Spin machine.
