Chapter 6: More Training and A Discovery

Weeks passed as the two trained each and every single day.

Running up and down the mountain as it started feel natural to the two.
Though that wasn't all, they both had to learn how to hold and swing a katana, doing it so many times that it felt like their arms were going to fall off.

Amira had a bit of an easier time only getting aches in her biceps as it has been awhile since she ever used them to climb around. She rarely made any sound as she accepted the pain in silence, understanding that it is necessary to help her protect the only two people she cared for .

Tanjiro always made sure she was doing fine once they finish their training, making sure to clean her old wounds and wash her bandages so her wounds won't get infected. 

The Kamados, unfortunately, learned that her injuries would either take a long time or they would never heal since her body hadn't carried a lot of nutrients, which was needed to help her body repair itself, so she unfortunately had to carry them for the rest of her life.

When Urokodaki first saw her without her bandages he nearly hit her since it surprised him quite badly.
Her face looked disfigured at the bottom with the left side missing skin which lead down to her neck. He also noticed her teeth, which seemed slightly pointed . If it wasn't for her training or her wandering around in the sun he would have thought she was a demon. This did cause him to be curious about what had happened to her but even Tanjiro didn't know.

Tanjiro had started writing in a journal that was provided by Urokodaki, in which he wrote a daily entry on what he was doing so that Nezuko can read them when she wakes up.

He wrote every evening, watching his sister sleep as they had called a doctor but there was nothing that could be done but just to let her be.
Each day his worry grew as he focused on his training with Amria . One thing his sensei had pointed out was her lack of understanding what they say so day by day he started to teach her specific words that would be important for her to understand such as "Run", "Danger", "Hide" , "Friend", etc....

Though Urokodaki thought it would be better if she learned the language as a whole as well as to read and write. 

And that was the beginning of her classes, which were going quite slowly since they didn't know what language she actually spoke so instead they took to pointing out things and saying the name or describing it with a drawing . 

Which meant she had to split her time between training and learning though it made her head hurt from the new language. 

At some point during their training they had to try attacking Urokodaki-sensei which proved to be nearly impossible since the old man was surprising quick and agile for his age. It always ended with them on their back even if both attacked him at the same time.

At another one of their trainings, Tanjiro was kicked into a waterfall with Amira following behind as she jumped in after him not wanting to be kicked in as well. Which ended with her being completely submerged as she floated quite easily with her light weight.

Then it started getting difficult, now they had to run down the mountain each day as it became more and more the dangerous which caused quite a few bruises and scratches on the two.

After that it was time for them to learn breathing techniques.

She was doing well with training but something she had a hard time doing was breathing in the specific pattern their sensei was showing them.

Urokodaki tried teaching her a few more times but her lungs weren't big enough and were a bit too fragile so he had to immediately stop her from continuing the exercise as it just kept hurting her chest and nearly made her cough blood from how much she was trying.
