The Only Aura User In Magic World

"Alright, it's my turn," I said as I stand up from my seat and about to jump to the stage.

"Hey, how do you fight? You're an air mage and a summoner, right? If you're a summoner, I think it's easy if you just let your familiar to fight instead of you," Sunglasses said.

It's not just him who think that way. The other new members of the alliance also think so too. Except for Yuria and Patricia. They already know what I am.

"This friendly match, although it looks like we did it on a whim, is actually planned by the four kings of the big countries. I'm sure of it. And they want to use this chance to properly introduce me to you all. About who I really am. Just watch and see why they decided to call me as the strongest hidden card," I replied.

Then I jumped to the stage all alone before making an announcement.

"Whoever want to fight me, then come down here! One on one, or as many as you want!" I said.

My First Match is Against the Angels
