"Don't get cheeky, girlie," said Josh.

"Oh she's done it now," thought Mary, "Surely Ann can't beat a black belt."

"Don't call me cheeky, just because you are too scared to fight me," said Ann, "I came here for a challenge."

"Look, you will be graded later on. There's no time tonight," said Adam.

"No time, that's silly," said Ann, "It won't take me that long to win."

"Look you might be good," said Josh, "but don't get carried away into thinking you can beat us. We're not the instructors for nothing, you know."

"Look let me fight you, and I'll beat either of you," said Ann.

"Either of us?" laughed Adam, "Ann, you should know that you fight more than one person at a time when you go for a grading. You could fight five at once, but I don't think you would cope with that."

"I still think that you are just too scared to fight me, aren't you?" said Ann, hoping to anger them.

"Alright that's it," said Adam, "We'll fight you, one of us, then both of us right now, if you can survive one of us, which you won't. This lesson will go on a bit longer. For those of you that want to watch and learn not to be smart alecs, sit around in a circle while we fight in the centre. The rest of you can go home."
The students moved into a circle and sat down.

"So who's going in there with her first," laughed Josh, "I don't feel sadistic enough mate. You can finish her off. I'll just supervise."

Adam and Ann went into the circle, bowed and stood in a fighting stance.

"Don't worry, I won't hurt you much, just enough to prove you're not ready for a grading yet," said Adam.

"I think you had better do more than that," said Ann, as Adam's forward kick crashed into her left shin before she could even finish her roundhouse kick. She felt no pain because of the exolimb.

"If you survive this, we will grade you equal to us," laughed Josh, and you can try for a job as a junior instructor at karate."

"You've got good staying power," said Adam, surprised that she had not reeled back from the pain that he believed must have affected her shin.

"I'll never out-karate him," thought Ann, "but I can use the strength of the exolimb if I get in close. He'll be expecting me to try an elbow effort."

She leaped towards him, blocking a high kick with her right arm, and then grabbed his thighs. Adam instinctively struck at her arms, but they did not move. Ann used her exolimbs to hurl him over her head to land two meters behind her, as two students rapidly moved out of his way.

"Oh that does it," said Adam, "Come on in Josh, and we'll still show this girl that us karate experts always support each other."

Adam climbed to his feet and moved in to face her again, as Josh entered the circle.

"Two of them will be tricky," thought Ann, "One can always act as a distraction for the other, so I will have to use one against the other."
