Training arc 2

[Seiji's POV]

Two years passed and I was 13 years old. This was when I experienced the hardest part of my training.

Studying.

Yes, apparently I had to study even in a fictional world where breathing was a superpower and in the year 1918.

It had something to do with my inheritance. There were real estate, business, money and other investments which were part of the inheritance. And in order to have them legally at the age of 16, I had to have at least a high school level education or 'chugakko' as they called it.

It was either that or I would only be able to access my inheritance at the age of 20. Which was bloody ridiculous because I might not even live to see 20 in my line of work.

I was more than aware of just how dangerous the job of a Demon Slayer was, more than anyone else probably because I watched a demon devour my sister alive and because of my past life knowledge.

Even strength could not assure your survival because it was the Hashiras and the strongest people who died in the end.

That was why I was so careful and not rushing into the forest blindly to fight demons unlike a certain wind pillar, even though I was already more than strong nough. Some may call it cowardice but I call it not leaving my life to the whims of luck.

Calculating the timeline of the cannon with my age, I would be 20 years old when we fight Muzan. That meant I might die even before I saw a penny of my inheritance so passing high school was a must.

So when I was the age of 13, I spent most of my time studying while also training my senses. I was deaf and that meant I relied heavily on my eyes and I had blind spots. So in order to make up for that, I had to sharpen my instincts and other senses to an extremely high degree.

So other than studying, I worked on my spatial awareness.

Luckily, I already passed middle school in my past life so I did not have to start from scratch and other than history and Japanese, I did not have to study much. Education in the 21st century was undoubtedly superior after all.

The exam for high school was nationwide. That meant that even if you didn't go to school, you could study by yourself and pass the exam. It was the eve of the First World War so no one had time to waste a whole day going to school so people mostly took this kind exam.

I was among them and after a total of 4 months of preparation, I passed high school successfully on my first try. My uncle and aunt were so happy with my achievement as even high school level education was impressive during this time.

After I was done with my exams and got my results, I finally focused on the most important aspect for demon slaying.

Breathing Styles.

I figured I would pick up the skill easily, especially with the transparent world. If people like Inosuke could invent thier own breathing style, why the hell should I not be able to?

"This will be a piece of cake," I said and looked at my reflection in the mirror.

My gaze pierced through my flesh and bones and I focused on my lungs which were noticeably bigger than average.

Lung training was obviously part of my physique training schedule since I knew how important it was. I trained using a gourd like it was shown in the anime and I also came up with my own method of training which included holding my breath for long periods of time.

Now I had a powerful set of lungs which should be able to support even the sun breathing, hopefully.

I had covered all of the basics. I had trained my body, and learned how to swing a sword - which was an understatement as I was the under 18 national kendo champion - and I had gotten familiar with my eyes as well.

The only thing left was to have my own breathing style.

...

...

...

...

Long story short, I was able to learn the skill but I failed to get a breathing style.

I could enhance my body thought breathing - I was probably the best at it since I had a massive advantage - but I failed at creating my own unique breathing style.

The concept of breathing style was simple, take in huge amounts of air in your lungs and absorb the oxygen. That would increase the amount of oxygen in your bloodstream, giving you superhuman abilities.

I was able to do that.

What I was not able to do though was find the pattern which differentiates every breathing style. I realized this soon enough but I think I would be able to succeed after seeing someone use any breathing style in action.

This was why after the initial failures, I stopped instead of trying to find the answer myself. Why wast time when I could get my answer by seeing a demon slayer fight once.

So, that's how I learned the basic breathing style. I called it, Steroid breathing (because it's true and funny). Everything you need to know is in the name.

It was an incomplete breathing style that did not have any particular special attribute but worked well in enhancing every stats I had.

After that, I finally decided it was time to end the training arc.

I was exactly as old as I was when I died in my past life. I was 13 years and 7 months old.

It was also the exact age Tanjiro was when his family was killed so I thought it was the perfect year. Both I and the MC would start our story at the same age.

So at the age of 13, I began my journey.

My main goal was to travel to Mt. Fujikasane for the final selection this year and on my way...

Hunt some demons.

That's right you ugly sons of bitches.

Revenge time.

Author : Three chapters released!!

[Status :-

Name : Seiji Shigan

..

Age : 13

..

Height : 5'5

..

Physique : Highly trained adult

..

Main power : Transparent world

..

Breathing style : Incomplete. Basic enhancement. (Steroid Breathing)

...

Sword skill : Easily Hashira level in sword skills alone. But he is still below Hashira when it came to fighting with sword as he lacks experience.

Meaning if it was swordman vs swordman, he would rival any Hashira in pure skill but in swordman vs demon, his sword skill may prove to be more ineffective.

..

Skills :-

1. Perfect Movement - This gives him the ability to move perfectly with no wasted strength or movement. It allows him to move by working only the necessary muscle groups so he can conserve energy but also make changes in his action mid-way. It is exactly as its name suggests. This no longer requires the use of the transparent world and remains passive unless he learns complicated movements or techniques which he has never seen or done before.

2. Body Language - This requires a transparent world and using this skill, Seiji literally understands body language. Even the tiniest twitch of your muscle or your breathing pattern and even your heartbeat tells him everything. Seiji can perfectly predict movements before they ever happen but this depends on how experienced the fighter is. If the opponent is top tier, Sieji might only be able to predict thier next move. You are telling him everything basically.
