Natsu's POV:

"Shut it, flames for brains!" Gray yelled at me as he swung a punch in my direction.

"You shut it, pervy popsicle!" I retorted, followed by a hard kick. The both of us were covered head to toe with scratches and bruises. There was even a bit of blood trickling down my chin. Dammit... does this mean he's winning?

"oomph!" I suddenly received a hard blow to the stomach and toppled over. When I lifted my gaze, I was a bit surprised to see that Gray had been hit too.

"Stop fighting you two!" Erza scolded in a menacing tone, "What happened? You two are usually so close."

I tried to smile the best I could, "S-Sorry, Erza,"Gray and I said in unison, but when Erza turned her back to us rambling on with some sort of friendship speech, we both returned to glaring at one another.

"Whatever..." Gray muttered and started walking away, hands in pockets.

"Hey, where do you think you're going?" I asked challengingly, "We're not done yet."

"Actually, I think we are done."

"We're not," I continued, "Fight me again tomorrow, and I'll show you who's a better fighter!"

Gray looked back at me; his gaze stone cold. It actually made me shiver. "I'm busy tomorrow," he muttered before turning away from me again and walking away.
