Chapter Text
Entry 1#
We thought if we killed Muzan all of this will come to an end. But even after we slashed his neck and forced him to absorb the sunlight. His reign continues throughout the Era. We had never thought that a small child that was the result of his blood. Would later continue his mission to conquer the world.
Thus, the government started to recognize the Demon Slayer corps officially. Our organization spread throughout the entirety of Japan. Protecting the citizens in the night. But the Demons were smarter and expanded outside of Japan into South Korea. Expanding the Corps further outside of Japan into South Korea.
Because of the fear of having demons in their country. The world outcasted Japan and South Korea, leaving us to handle the problems ourselves. The Corps was still a secret even though the government now recognizes them. It was kept like that not to make the citizens afraid.
Until now, the location and the identity of the new Demon Leader are still unknown. Some speculated that it was another person who has the same sickness as Muzan. Thus, giving them the power to create a demon with their blood.
It was a goose chase, and the tradition of killing demons in the night was still implemented. The Corps needed more troops because they keep on spreading and sometimes more lethal. None of them was cooperating either, and It scares the Corps a lot. Because back then we have a lead, and It was my sister, Nezuko Kamado.
The only demon who was able to speak and conquer the sun. But since her death. The Corps was running blind, and I was the single lead. Time is also running out on me; I still haven't found a successor to teach the Breath of The Sun and The Dance of The Fire God Techniques.
I am starting to lose hope; will there be anyone to replace me?
Entry 2#
I found a girl's body in front of a small house; She looked young. She was unconscious and covered in blood. Her home was ransacked, and her blood was splattered everywhere. It reminded me of the past. It looks like the girl was still alive, her body was warm, so I piggybacked her back to the Ubayashiki's estate.
She was still unconscious, and she has a fever. Her body temperature was high, so I bring Kanao along to check up on her. She said that the girl was fine and said that she just needed some rest. So we let her be. She looks like Nezuko when she's asleep. The poor girl had lost her family. What should I say to her? And How should I explain it to her?
Entry 3#
It has been weeks since the girl passed out. One night we heard a ruckus coming from her room. When we went to check on her, we were in shock. The girl got a seizure her eye was red, and I could see her veins popping out of her skin. The medical team tried to hold her so she could stay in bed.
Her mouth was open, and slowly we could see the fangs that were starting to show. She was changing into a demon. But what I see from the see-through world was different. She was fighting off the demon blood, that was circulating in her body.
The blood was pumping fast inside of her, and all of us didn't know what to do. Kanao suggested slashing her neck. To just end her misery right there and then. But I rejected it; I couldn't smell any Demon blood inside of her. Even though inside there is some of it circulating inside.
But her smell was different. It was almost the same as Nezuko's, just after she conquered the sun. Her scent started to camouflage, and she acted usually. This girl was different, and I could smell it. We hold her off for an hour until she passed out.
We couldn't take the risk of her eating us in the middle of the night. So we tied her off to the side of the bed with a rope. Thus she couldn't runoff. We told the Ubayashiki about this, and they told us to have a meeting in the morning.
Entry 4#
The next morning we had a meeting with Ubayashiki Kiriya. We were told to watch and keep her. So we could analyze her since the demons are getting much stronger than how they use to be.
In the middle of the meeting, one of the Kakushi informed us that the girl is now awake and she seems to be healthy. I was the first to run to the ward, and they were right.
She was sitting straight on her bed, eating her breakfast. Now with new chained handcuffs to held her from attacking others. She looked at me with gentle expression. Her left eye was red, and her right eye was blue.
I couldn't smell anything wrong from her. She seems beautiful and healthy.
When I asked her who she is, she just to told me her name and her reason. Her name was Yoo Jeongyeon. She's Korean and moves here to Japan for a living.
I asked her if she remembers anything from last night, and after I asked her, she started to react differently. I smelled something odd from her. It feels like the demon's blood. I was holding my blade tight, scared that she would change and attack but what comes next surprises me.
She was beautiful; her eyes are now both red, and her veins are popping out. But she was acting normally; she didn't even react to the sun peering through the window. She manages to control it and I ever so slightly heard her speak.
Then she looked at me with teary eyes; I can smell her anger and sadness. She told me that a pale young boy came into her house. He was demanding someone be the sacrifice. Her father said no, and tried to get him out of the house.
He just smiled and grabbed her, giving her only a scratch and left. She then felt an immense lot of power inside of her, and she was salivating just by the smell of her family. She was conscious when she devoured them alive. After that, she changed back to normal.
I didn't know what to say after that. Kiriya told me to looked after her, so I did. I moved her to my mansion, so She was under my watch. She knows what we are and wanted to join the Corps. I was not sure whether or not I should teach her.
But, Kiriya said she was a great asset, and I needed a successor. So I became her Tsukugo, She was stronger than I imagine and I just noticed she had the same Demon Slayer mark like me. The same fiery mark on the forehead.
She was the first demon ever to become a demon slayer. She could change back and forward from a beast to a human to her liking. She was strong, and Kiriya said the perfect candidates for a pillar. The new Sun pillar.
Entry 5#
I didn't know that my time was running out early. If you are reading this Yoo, that means that you have heard the news. He has finally found me. I leave the rest of the Corps to you, and I hope you do well. You have to protect those who are weaker to you and show your opponent some respect.
There is always the right side in you, Yoo. You are more than just a demon. You are reasonable, and you can protect them. I believe in you.
Don't worry about me. I'm going to meet Nezuko in the afterlife.

The book fell from her grasp, and her feet felt like noodles. Her Sensei has just died, and It was all her fault. She came too late; He was already cut to pieces with nothing left. Vengeance was all that she felt. She promised her self that she would avenge him and her family.
She gripped his checkered green haori which was in half tightly as tears run down her face. She gritted her teeth and held her Sensei's sword. Because it was all that she was left with.
"Kibutsuji Maori, I will chase you around Japan even South Korea, and I will slash your neck."
