The Only Aura User In Magic World

"So you will fight underwater today?" Kayla asked me.

It's the day of the match. And I'm ready to fight.

"Yes. I will fight Crabbe today. I'm curious to see how strong he is. Though I will get Spot and his children first. They are the only ones who can watch our fight and wanted to do so. Though there are other monsters who want to watch but they can't," I said.

"What about those chewing leaves? Anyone should be able to breathe underwater and watch you fight if you give them," Angela asked. I guess she just wanted to get one so she can watch our battle.

"They are consumable items. And there's only nine of them left. I'd like to save them until the battle. Because even if we have the Crab People to join us, there might be too many of them to fight and they will need your help," I said.

In my past life, there's no battle on the sea. At least I don't know if it happen or not.
