Chapter 2: Training

They arrived at his house by lunchtime and after they picked rooms for each one they ate and Giyuu explained what the Demon Slayer Corps was, he told them about the ranks among them and about their breathing techniques.

He planned a training for them so they developed the total concentration breathing, the healing breathing and how to keep them even in their sleep. He will work first on their body to get it stronger then he will work on their kendo.

After dinner he was in his bedroom when his crow flew in "new mission, new mission... Head north, head north... There are women disappearing"

He signed and got up and put on his haori, then wrote some letters and sent them. He stood up and walked to both kids.

"Tanjiro and Nezuko. I have to go on a mission. I have to go for about a month or so. I won't be able to train you so I will send you with two people of my total trust, one is my master Sankoji Urokodaki and the other is a fellow Hashira and friend, Shinobu Kocho. Please enjoy and learn everything they teach you. When I return you will learn the Water Breathing techniques with me so you have to be strong" they nodded and Giyuu left after that.

The next day they follow the instructions to get to Urokodaki's home and to the Butterfly Mansion.

Once there Nezuko met Shinobu and after putting her stuff in her room, the training began.

The insect Hashira made sure Nezuko practiced Total Concentration breathing and how to keep doing it even in her sleep. Also doing training to gain strength, have a fast movement speed and become a better warrior.

On the other hand, Tanjiro did the same things plus increasing his sense of smell by surviving the traps Urokodaki put down the mountain.

During that month both Kamado siblings became stronger. Nezuko even learned how to do the power thrust that made Shinobu a powerful Hashira and she became friends with Aoi and the three girls that worked at the mansion, and even Kanao exchanged a few words with her which, according to Aoi, was quite rare.

Tanjiro enjoyed his time at the mountain as it reminded him when they were happy with his siblings and mother. He signed and this led to sharing his story to his master and he also told him about his time as a hashira and as part of the corps.

The month passed by faster than expected and both Kamado siblings became stronger and were able to master the control of their total concentration breathing and the basics of the sword. Now the next step will be learning how to use the water breathing.

When their last night arrived Nezuko ate dinner and went out to play with the girls. Shinobu looked out the window at them and sighed.

"Dear sister... I want to apologize to you because I envy those two girls..." She said looking at Nezuko and Kanao outside "they are younger and are almost the same height as me, and they are stronger and I'm sure they will be able to decapitate demons... I'm seventeen so I need to behave myself" she sighed "but at the same time I'm so proud of them and I'm looking for them to defeat that demon that killed you"

She took a deep breath and smiled as she watched them playing and relaxing. Tomioka must be already arriving home so she will take Nezuko with her and have a chat and maybe give him some of his favorite snacks.

Meanwhile Tanjiro and Urokodaki ate a lot of food and chatted. The old man missed having a young person with him, he missed talking with others about his profession and how he survived a lot of battles.

The next day Tanjiro left early and went to Giyuu's house. Nezuko left with Shinobu and by noon both siblings were reunited and talking about what they did.

While Giyuu spoke with Shinobu, holding his master's letter as well.

"You and my master did a great job. I knew I could trust you with those two"

"I'm curious about Tanjiro. He seemed different from Nezuko"

"He has an amazing nose. He can smell even the emotions. Nezuko seems less skilled but as you told me, she's strong and mastered in a month your trusting technique"

"Yes and she managed to hear to Kanao's voice which is something weird"

"Yeah, she's beyond quiet" he said, looking at her "now that I will start with the water breathing. I hope you and Kanao can come to train with us" she nodded, surprised by his proposal but very happy for that.

Then she left and the training began. He taught them the first form and both kids practiced it all day until it was natural for them.

He decided that he will teach each form, day by day and then they will fight with bokkens against each other.

Giyuu noticed that Tanjiro had troubles with some techniques but maybe in the end he was able to do it. However Nezuko seemed more natural and learned them faster.

After they learned the eleven forms they started to practice in real combat, he made sure to add a prize for the winner so they would put some effort in the practices.

Sometimes he even fights with them in a one vs two. It was easy for him to win but as they mastered the water breathing they became stronger. It started to get harder to win.

When Kanao joined them, the same thing happened. At first she seemed very superior but the two Kamado siblings grew stronger and faster. Their teamwork made them stronger but when they were fighting in a one vs one.

In the end it took a year and a half to be ready for the final selection.

Giyuu gave them two swords he has as replacement for his official sword. Then they left with Kanao to the mountain where the selection will be held.

OOooOOooOO

This chapter was fun to write because I wanted to show both training and then how those two grew stronger by the day.
