The breathing styles

Y/n's POV:

I woke up early in the morning doing a quick morning stretch session before getting dressed. As I got ready I wondered if Miss. Kanorji would do an different hair style than a braid? My red hair was getting long like it was already almost to my butt.

But I love my long hair and I'm not cutting it off. Not ever!

I picked up the book and as I left to go and train it was early in the morning like the sun was just coming up. I stopped to looked at the sunrise for a bit it was beautiful.

Then I continued my way I even started to read the book again as I walked to Mr. Renguko's estate. This book was interesting, did he actually learn how to be a demon slayer with a book? It's really cool.

I was walking when a strong gust of wind blew at me, making my hair go crazy. I had to fix it, but lucky I had an hair tie and I put up my hair
(A mirror like Yoriichi)

I was at the door and I knocked them went inside. Rengoku was already in the backyard waiting.

"I see you brought back the book."

I looked up at him and nodded.

"Yes, I finished it last night, a very interesting book I shall add."

He smiled and I put out my hand that held the book and he took it.

"Yes, this is the book that taught me."

"Really? Did you learn from the book?"

"Yes I did"

"Awesome"

No one' POV:

For the next hour or so renguko was testing your reflexes and they were very good. In his eyes you were improving a lot but you still needed to learn a lot.

Now he was teaching you how to use the breathing technique now.

You stood and and breathed in and then out breathe in again then lunged at him.

"Ok now... Flame Breathing: First form: Unknowing Fire!"

When you did this you broke the wooden kanata's as a fire-ly thing followed the sword you held in your hand.

When you stood beside him as you held the broken wooded sword in your hand.

"Well done, you learned the first breathing form" he said as he turned to face you as you did the same.

"Once you well the forms I'm going to teach you. You'll be going to final selection."

You spent the whole evening learn all of the breathing techniques and forms. He taught you six forms and when the training ended you were on your way back to the butterfly mansion then you remembered what Tengen said.

"Tomorrow come and duel me at the same place I training you."

You change course and went to the forest.

You ran and ran up the mountain effortlessly you remember the last time you ran up the trail. Your legs would burn as your breathing will get messed up easily but now... it was different.

You arrived where tengen wanted to meet up but he wasn't here... or was he? You dodged as something came at you. Then a wooden sword was in front of you as Tengen stood about five metres away from you.

"You go first!" He yelled

You lunged yourself at him you were about to hit him but in the next second he was gone. Then you whipped your body just in time to block the hit from about.
