Adversary

/ˈadvərˌserē/

Noun

1. One's opponent in a contest, conflict, or dispute.

Aera stumbled back violently at his swing. A regular occurrence.

He was good. Far better than her.

"Is that all you've got?" He smirked.

Aera struggled to get back up. She placed all her weight on her wooden blade for support.

She groaned. "Not on your life."

"All right. Well then give me your best shot."

She launched at him yet again but deep down she knew.

It was near impossible to surpass him but that didn't stop her from trying.
