Tsugoku Of The Insect Pillar

I sat there in shock, Nee-san didn't teach her that. So how did she know how to perform the techniques?

"How did you learn that?" I ask Kanao due to the confusion it brought.

"I learn by watching Kanae-san perform the techniques." She replied.

"You learned by only watching? Did Nee-san teach it to you too?" I answered.

"No, she said I was not physically trained enough to learn the techniques." She said simply.

I hesitate before asking her "Kanao, do you want to be a demon slayer?"

"Yes." She said.

"How about becoming a Tsugoku?" I ask.

"As long as I am a demon slayer, any rank or position is fine." Kanao said.

"I want you to become my Tsugoku. Do you want to?" I said, not sure if she wants to be next in line as a pillar after what happened to Nee-san after a pillar level mission.

"I am willing to become your Tsugoku, Shinobu-san." She said, when she didn't flipped the coin, I had hope she can now make choices on her own, so I put that theory to the test.

"Very well, do you want to address me as the Master of Butterfly Estate or as your adoptive older sister?" I ask hoping for her to chose without relying on the coin.

"Also, you don't have to force yourself if you don't want to go on missions if you can't." I add hoping to help her at least by these words of advice, being a woman is difficult, especially when you work in a battle environment when you're on your period.

Destroying my hope, she pulled the coin out of her pocket and flipped it, it landed on tails, after seeing the results, she looked up to me to answer.

"Very well, Shinobu-sama," She started to say, which made my hope completely disappear, even if she used the coin as reference, I had hoped for her to at least address me as her older sister.

"I expect you to understand that even when you are already a demon slayer, you still need to train yourself to improve." I say ready to train her as my Tsugoku.

"Yes, Shinobu-sama." She replied.

"That's good, this is all we have to talk about for now, you are dismissed." I answer.

After she left I started to give my sword it's daily maintenance, seeing as the poison is low on supply, making more was what I did to pass time as I didn't have any missions coming in.

More demon slayers came in injured, the blood demon art seems to be concentrated poison that attacks vital organs. I try the medicine I made to repel blood art made poison, after testing it on my self, it is probably done with the experimental phase, and can be used on other people. To my surprise, it did work.

Planning Kanao's training regimen is going to be hard, a lot more than I speculated, if the training is too intense for her, she can possibly die from exhaustion before even getting stronger, but should it be too easy, she would get stronger, but gradually. And with Kibutsuji Muzan showing that he is being active during this time, that isn't safe. He is, no doubt, more phthartic than before, considering that the last time he was seen was in the sengoku era.

A/N
Hee hee man killed Tanjirou's family right? How did the corps not detect that? Because they probably did. Hence, Shinobu saying Muzan was making himself known and worrying about Kanao being a demon slayer around this time. Oh, and about Shinobu showing emotions when she actually keeps them inside her and hides it behind a smile, in this fanfic, I aim to capture her internal anger, emotions, and conflict in first person.
