ittle Information;
Kamado [Name] and your breathing would be the Sun breathing. So to be accurate, you're the second user of the sun breathing who's the first user was Yoriichi. This is a little bit connected to the first oneshot of Muichiro, so, for Kamado [Name], I'll use [Name] but for the Y/n in Muichiro's shot I'll call her Wayen (pronounciation of Y/n). Please understand, English isn't my mother language and I'm bad at explaining.

☆ミThird Person's POV

"My, my ..." a sudden voice said. Shinobu, Mitsuri and Muichiro are now weaker and can only blow two or three more attacks. They looked up and saw a lady in a haori and had a veil to cover her face.

"Tch." the demon said and about to attack when he stopped by the stranger's breathing. "Sun Breat-" before she could even charge her attack the demon disappeared.

"Muzan-sama said I should avoid that user." he said as he went further and now not to be seen. "Wayen, Are you okay?" the lady asks as she assisted her student and makes her drink medicine.

"Muichiro-kun, Shinobu-san as well as Mitsuri-san can you walk?" she asks as the three of them nodded. "Let's go, luckily, Kuroiro was able to find my crow and report to me. The one you encountered was Douma, the one who killed your sister Shinobu." she said and Shinobu's smile faded.

They left the place, the stranger still carrying her student. "Who are you, miss?" the love pillar asks as they were running, taking their way back.

"I'm [Name], Hashira First Master," she said and make them stop. "We're sorry." Shinobu said as they kneeled down. "No need for formalities, were almost near." she said and they nodded.

They went back and put Wayen in the mansion. The unknown presence of the first master that only Muichiro, Mitsuri and Shinobu knew. Their comeback was a timing for the hashira meeting. With her presence near the estate, she needs to attend the meeting once in a while. As the first master, the hashira didn't know who she is or does she even exist.

The three who backed Wayen up will be staying in the Butterfly Mansion to rest. "The master has come." Kiriya said and they all kneeled down.

"What a surprise, you're here [Name]," Oyakata-sama said. "I came back because Kuroiro reported to me the sudden presence of an upper demon during my student's mission you gave her." she answered still in her veil.

"Student?" They asked and she stood up and went beside Oyakata-sama. "Wayen is her one and only student." Kiriya said. "The one who saved Wayen." Kanata said.

"Which means ..." Rengoku said as he was finalizing all of it. They lost their tracks and looked at her. "Yes, I am [Name]. The Hashira First Master." she said in a soothing voice just like the way Oyakata-sama speaks.

"What is the sudden meeting, Oyakata-sama?" Gyomei asks and Oyakata-sama smiles. "They're moving again. Muzan and the 12 Kizuki." he said.

"Also, just as I told you before. Wayen, and the three who backed her up, Shinobu, Mitsuri and Muichiro can't do anything" Y/n spoke

"A-are they okay?" Obanai suddenly said and Y/n smiled. "Only Wayen was badly injured, Shinobu and the others only lasted for a minute. Until I came in, they're safe so you don't have to worry about them" she answered

"So, as you took your way out of here. Train yourselves, make sure to strengthen everything about you and your breathing concentration. Also, Kyojuro-san. I would like to appont Wayen to you if you don't mind. It's easy for you to teach her more since lava isn't my breath." she said.

"If you don't mind [Name]-sama. What is your breathing and why is it that you don't attend and almost no one knows you?" Sanemi ask.

"My breathing is one of the most hidden secrets in the Demon Corps but if the time comes, I'll tell you." she said and took a deep breath, "And also, I don't want to bring anyone in my mess. Muzan wants to kill me first than any of you and it's all because of my breathing. The second question is that because of my breathing and also for my long mission. I'm undercover and trying to research for the Blue Spider Lily Muzan wants to own. I'm also having a mission for guiding you down. I'm the one who's giving missions to Tomioka Giyuu, Shinazugawa Sanemi, Uzui Tengen, Gyomei Himejima, Iguro Obanai and Kyojuro Rengoku. The ladies, Muchiro and the lower rank slayer's missions are from Oyakata-sama. Since they're still in a young age, they still have a greater future and also can become stronger as well as you six. The stronger you get, the harder the mission," she said.

"So, as I am saying. You better train the others as you train yourselves. You can pick someone or train by yourselves. Good luck" she added as they nodded.

"So, [Name]. Besides the reasons you said before. Did you come back because of them?" Oyakata-sama asks as Y/n joins him in his meal.

"I overhear that he's asking for the Kagura repeatedly. As I came back, I asked the people living in the village and they said that the family was killed." she answered and sip for tea.

"Well, when will you tell them?" Oyakata-sama asks. "On the day that he's the one who will approach me and ask what it means," she answered.

"So, how were you able to get that hanafuda tie hair?" Oyakata-sama asks. "I saw it in my mothers belongings when I visited the house" she simply answered.

-

"Ne, Tanjiro. Have you heard? Wayen-chan, Muichiro-kun, Shinobu-san and Mitsuri-san were rescued by the First master." Zenitsu said.

"That's right, the first master began to serve Oyakata-sama at the age of 8 because of her intelligence and skills," Aoi said.

"But her sudden presence is bothering, she was last seen 8 years ago for a long time dangerous mission." Aoi added.

"How old is she at that time?" Tanjiro asks

"10" Aoi answered and they gulped. "10?! On a dangerous mission?!" Zenitsu said freaking out.

"Her existence only exists to those slayers that are close in the estate, in other places, she's just a myth or a legend. Her existence must not reach the other side because she's the ace of the Demon Slayer Corps." Aoi added.

"Where did you even get that information?" Inosuke ask.

"At the Demon Slayer Corps Library, also , Tanjiro," she said. "Better check it out, maybe you can get something connected between you and to her." Aoi said as she remembers that the girl also has a mark on her forhead and figure almost the same as Nezuko except the fact that she has e/c eyes and f/c tips on the end of her long black hair and has a bangs put on sideways. Also has a hanafuda earrings in the picture.

-

Tanjiro frozed as soon as he found the information about the first master. He can't believe it, he suddenly dashed towards the estate of Oyakata-sama and asked where this [Name] were.

He went on the dojo carrying a box with Nezuko inside. The door is closed and it's dark, only a few candles can be seen. He tried not to create noise until he heard something that makes him freeze.

"Total Concentration Sun Breathing; First Form; Hinokami Kagura!" she said all of those were witnessed by Tanjiro and her sister Nezuko.

Seeing the First Master not wearing a veil, [Name] suddenly looked back and saw them watching. "The time has come I guess." she said.

"I am Kamado [Name], the second Sun Breathing user. I was able to utilize my ability for such a young age. I started to move out so that the rest of the Kamado won't be included in that, I, inherited the Sun breathing from Yoriichi. You were forced to erase all the memories you had with me so no one would be affected but it turned upside down." she said.

"Y-you're our sister?" Tanjiro asks and Oyakata-sama comes out. "Yes, she is. We took her out for the safety of the rest of the family where she belongs. Inheriting the breathing of Yoriichi Tsugikuni would lead for Kamado to be erased. Yoriichi Tsugikuni is the only one who has the highest possibility to kill Muzan way back. Seeing you having those hanafuda earrings makes him remember Yoriichi. When she heard what happened, she went back to check her younger siblings and cut her missions."

Tanjiro suddenly throws self to the First master as well as Nezuko. A lot of people, the hashiras, tsugoku and the others showed up.

Seeing everyone happy because of this.
