Well, Zelda, if you want a sparring partner I could probably fit the bill. But I'm not exactly familiar with fighting unarmed...

[And she doesn't exactly want to swing her Keyblade at someone who doesn't know how to fight.]

Maybe some sort of serious exercise? Weight training, sprinting, maybe swimming? The water could cool you down, too.

[She's an islander, she'll work swimming into the solution if she possibly can.]
