Nezuko slowly opened her eyes due to some light. It wasn't the usual orange light of sunrise. It was a pinkish one. She looked in front of her, still tired. It's only some seconds later she noticed the sound of crackling fire. It made her get out of her futon and look around. Her brother wasn't here anymore but she saw where the light came from. She followed its path and saw something she couldn't believe.

Tanjiro was sitting there with her nichirin blade in his hand and pointing at his neck. He was covered in blood. The latter burning on his skin with majestic pink flames. The demon slayer didn't hesitate a second before taking her brother in her arms and making him unable to use her katana.

She then took it firmly and threw it away. She kept her only family in her arms while she was crying out loud. She didn't care if she would get hurt by the fire, she just wanted to stop the boy. "Tanjiro, what the hell are you thinking?!"

Mister Tsugikuni entered the room and was shocked by seeing the siblings, he tried to separate them but Nezuko was sticking to Tanjiro too hardly. The demon was still burning while screaming out of pain.

The pain. Nezuko didn't feel it. She wasn't burning. Only the boy was. Tanjiro's body temperature wasn't that hot either. It was the same as last night, at least. He kept on screaming but the girl didn't hear anything now, she put her hand to her brother's neck to find out if he was able to cut himself. She felt the wound and her hand on it, in hope it'll make him regenerate faster. She now had blood on her hand and it now burned too.

At that moment, Mister Tsugikuni left with a bucket to go to the nearby river and get water to stop the fire. He came back as fast as possible and threw it at Tanjiro. The blood disappeared and the fire did too. The demon took his toddler size and kept on crying while the burn scars were healing. Mister Tsugikuni came closer with an extremely worried look on his face.

Days later, both demon slayers kept on watching the Kamado brother. The man made a box for Nezuko to be able to leave with him during the day and after some time, the girl left with Tanjiro and got to her first mission. It was in a small town where multiple girls mysteriously disappeared. (Since the author is a loser at writing fighting scenes,) Nezuko ended up defeating the demon quite easily and was able to save two citizens with the help of her older brother. Sadly, it was impossible to bring back the demon's victims. Though, that was how life was and the dead will always stay dead and we need to move on no matter the loss.

Some days passed and Nezuko made sure to emotionally help her brother so he would not try to do that again. Then, one day, a crow told her to go to the capital and find another demon. They arrived safely and they ate some noodles at nightfall. At least Tanjiro tried. It seemed like making a demon eat anything else than meat was a hard task.

Suddenly, the boy smelled something and took his younger sister's hand to run in the crowd. Nezuko didn't understand but quickly took her brother's scarf in her hand. She didn't like the idea but she brang it to use it as a muzzle in case he tries to attack a human. The thought of that kind of scenario happening made Nezuko sick but it sadly still was an option to have in mind.

She followed her brother in the crowed street. It was impressive for her to see a place with so much light at night. When she lived with her family or when she trained with Mister Tsugikuni, they had to use candles to have at least a little light inside. Or they had to wait for a full moon but it only happened once a month so it wasn't the best technique.

Tanjiro finally stopped running and Nezuko saw a man with dark red haired tied on a long ponytail... She thought she had recognized the man and took his shoulder and asked "Mister Tsugikuni....?"

He turned around with a surprised face. He looked almost identical to Mister Tsugikuni. The only differences were his eyes being pink and his hair was slightly different. Well he wasn't scared on the bottom of his face and had some strange birth mark on his forehead. Noticing she mistook this citizen for her master, she bowed down and apologize quickly "I'm so sorry, sir, I thought you were someone I knew!"

The stranger looked at her and smiled gently "It's alright Miss, mistakes happen."

He looked next to Nezuko and saw her brother. He seemed very angry which surprised the sister. She then got her eyes back on the man and noticed his slightly scared face. She didn't dare to ask him anything feeling something was wrong with him. If he made Tanjiro of all people angry with only existing, it probably meant something. Maybe her brother smelled something with this man who suspiciously looked a lot like her old teacher.

Then something came back in her mind. Something Tanjiro mentioned three years ago when they first met Mister Tsugikuni. It was something like "You look like him but you don't smell the same."

So was this man perhaps the one who had killed the rest of their family....? Was he Yoriichi...? The demon king himself right in front of them ? He was in a crowd space so it was maybe a good occasion to... Suddenly a woman came in and talked to Yoriichi "Sweetheart, is something wrong?"

The demon king turned to her and seemed way calmer "No, everything is okay, Uta. Those kids just confused me for a certain 'Mister Tsugikuni'. I was telling me it was alright." He looked at - who Nezuko thought was - his wife. His then slowy went to his watch and softly said "Sadly, I need to go, I'll see you soon, love."

The man then left the crowd leaving the Kamado siblings speachless. The younger one then noticed a small movement. She got confused before seeing a man having spasm. She looked at him in worry. The man then attacked a woman close to him. Nezuko ran to him and put Tanjiro's scarf in the newborn demon's mouth to stop him from attacking. A piece of clothing wasn't the best muzzle in the world but still could help a little, she thought.

After some minutes, the police arrived but Nezuko was scared to let go of the demon."Please, let me take care of him! You should check on this person's wife while I'm calming him down!"

It was no use, the officers weren't listening to the girl and tried to forcefully get her away from the man. But if she let go, he would go on a rampage and maybe kill someone! She then tried to find hope the crowd all around her, focused on the unfamiliar scene right in front of them.

Suddenly, the demon slayer noticed a man with some weird pink spot on his pale face. He had a gentle smile on his lips and his lavender eyes only showed kindness. His hair raven were in a perfect shoulder length cut and he was wearing a black kimono accompanied by a white haori fading to red.

The unknown man rolled up his sleeve and then cut into his wrist with his surprisingly long and sharp nails. Nezuko assumed he was a demon because of them but something inside of her just didn't want to attack him as she should. Blood slowly dripped down and... Everything around Tanjiro and Nezuko like some unrealistic painting of flowers. Was that the stranger's blood demon art ? Seemed likely.

The policemen got distracted and the one infected by Yoriichi's blood disappeared from her sight. She panicked but quickly tried to call down. She then heard the demon speak softly. A young girl in a lavender kimono like her eyes. Her hair were black which found non-fitting to the color of her outfit but it didn't matter. "Nezuko Kamado... You still see this man as a human...? Even though he's been turned into a beast my this monster called Yoriichi Tsugikuni ?"

Nezuko didn't know what she should be concerned about first. The fact she heard this voice before months ago ? The fact the demon king actually shared last name with her master or the demon calling his progenitor a monster ? The girl didn't know at all and was very confused. She moved her hand behind in hope to reach her brother's. She didn't leave the two other demons from her sight but she felt Tanjiro shaking. Was he scared of the strangers or startled by by the mention of the name "Tsugikuni" like his younger sister ?
