Slayer of Time (Demon Slayer X OC)

Chapter 6: Yoriichi?

A/N: 

I uploaded and added some new descriptions of my character Mizuki, like her appearance.  (This is for readers that have read this story before I made changes)  

But if you don't want to go back and look at chapter 1's description than here it is:

Her appearance like the picture and description like before is the same (Appearance: Has long dark brown hair with light brown Hazel eyes. 5'5. Is decently fit, on track and field. Has a cute look to her, she thinks that she is average in looks. She admits she looks cute at times but not really pretty.  However, she can be considered pretty by others but not herself.)  

Appearance in Demon Slayer: Still has the dark brown hair, however much darker than before, which can be considered almost black. Still has Hazel eyes and a cute face/pretty face. Though her hair at the tips have a silver blue tinge to it. Though her body/fitness is much more built and trained in her upper muscles and she had to train again for her muscles in her legs. She is overall more fit than she was before.     

Mizuki POV 

Not too long after the stunt with Yoriichi, did I see a little difference in attitude with Michikatsu.  Michikatsu would often go up to Yoriichi at times when Sato-san wasn't around and ask him how he was able to beat and land hits on our teacher. 

I too would go along and listen to the explanation and hear out what was going on or how he was able to do it.  Remembering the attacks landed on the man, it was smooth, fast and swift.  It was an amazing sight to see. 

But each time Michikatsu would ask Yoriichi would kind of explain it as "focusing your breaths and concentration on your target."  but also it was kind of confusing since he didn't really know how to explain it.  

Though after explaining it somewhat he would then beam at Michikatsu saying that he wanted to fly kites and sugoroku with him.  Each time he said that I would smile and giggle at that.  'How cute~'  I thought each time. 

However thinking of what Yoriichi said I thought that it must be the early form of breathing techniques which the demon slayers use.  After training and regular routine I would go to my room before heading to Yoriichi and kind of meditate. 

During meditation I would try breathing differently and racking my brain 'how did they do this?!  What did Tanjiro do?'

But each time I remembered what and how Tanjiro explained it and the training was him puffing out his chest and saying that his lungs hurt like it was about to pop and made "Boom Boom"  sounds.  I shook my head and sweatdrop  "What happens if my lungs actually do pop?!  They don't have advanced medicine or tools here to save me?!!"  I mumbled to myself as I shot my eyes open. 

"This is not working....."  I say to myself now getting up from my position.  Walking around my room, walking back and forth.  "He got a gourd and worked out.....Maybe I have to work my muscles out more...."  I thought looking back at my training that I did.  I nodded.  "I have just been working on my sword techniques and fighting techniques but not muscles."

I thought about it some more in deep thought and widened my eyes.  "Wait!!  This training with the gourd is not for breathing style!  It's concentration breathing!  I'm so stupid......But I still have to learn it anyways...."  I say to myself ranting and having small tears come down my face. 

I sigh out and ruffle my hair a bit.  'I guess I'll go see Yoriichi now.'  I told myself as I left my room.  I quietly made my way outside of the main house and walked over to the small room.   I knocked on the door and entered.
