Chapter 5

❝ Derivative ❞

"HRRRRAAAAAAAHHHHH!!"

It's been nine months since Y/N had passed the test and now, those gory screams would be heard within the mountain everyday. The higher you go up the mountain, the thinner the air gets even to the point that some would suffocate. Y/N, for instance, almost died on the first three days. Though she slowly got the hang of it. Her task was to go to the peak of the mountain and go back down within the day, otherwise, she would have to do a hundred push-ups over blazing charcoal.

Of course, the trip up and down was not ordinary, it was filled with traps and sometimes even a few demons at night. Thanks to Y/N's past extracurricular activities, the only true hassle she had to overcome was the breathing and demons, and occasionally a few deadly traps. She was used to parkour.

Shiro on the other hand, was tasked to oversee Y/N's training. Shiro constantly commended Y/N in her head since she could see how she had reached all of Koyuki's expectations despite the immense difficulty. Truly a hard-working child..

The training would change from time to time in order to test the girl's adaptability to different situations. Sometimes it would be the usual mountain routine, sword training, flexibility assessments, endurance, and etc.. Today was a mix of two. The mountain routine and sword training was combined. Koyuki decided to let her do this during night to let her fight a few low level demons and avoid traps.

Shiro had Y/N's kill count in her mind ever since she started.

Current kill count: 11

Even Koyuki was surprised by the progress that Y/N was showing. Though there was only one problem..She couldn't master breathing techniques. Yes, the girl was definitely better than the majority, but it seems that she had to trade it for the learning of breathing techniques. And that was the crucial part. Koyuki admitted that Y/N has only been learning it a few weeks ago but, she couldn't even release the first form of Moon Breathing. Not even a single slash.

After Y/N returned to Koyuki's house covered in scratches and sweat, she immediately cleaned herself and decided to rest. Koyuki watched her the whole time. She then decided to finally have talk with Y/N regarding her training.

"Y/N, you should know that I'm happy seeing the results you've been making these past few months but.."

"But I can't learn the Moon Breathing technique you have.." Y/N was dissapointed.

I got overconfident that I could change the plot with my progress..Seems like I got too full of myself..Koyuki noticed how depressed Y/N started to become these past few days. She then got an idea pop up in her head.

"You know..You don't actually have to learn my breathing technique right? You could just make a derivative out of it! Yes! Create your own breathing style! Though it is harder than learning one that already exists, I'm sure it will work out for you!" Y/N perked up at that suggestion.

Right..There are lots of people who created their own breathing styles..Shinobu, Inosuke, and Mitsuri! Also Uzui, Iguro, and Muichiro..I think? I think they made their own too..

"Y/N, these past nine months, I was able to teach you everything I know which was all due to your efforts. How about this, until it's time for the Final Selection, I won't be teaching you anymore. I will be here when you need guidance. I've been watching you engrave everything I taught you in your head. I'm confident that you will pull this off." Koyuki said warmly.
