Tanjiro's P.O.V

I'm sure you guys remember how did I joined the kingdom of Ruberios. If you didn't, let me give you guys a recap. I was selling charcoal to people at a village by the mountains until I was attacked by a masked villain that I defeated easily. Then I saw the bag was moving so I opened it and it was a princess named Flora Beltrum. I took her to my house since she was lost and I didn't know where the castle was. The next morning, 5 new people came to our house and thanked me for saving Flora, they turned out to be Flora's sister, friends, and her knights. A woman named Hinata asked me can I and my family could come to their kingdom to meet the king. My parents nod at me, so I take their offer. When me and my family got to the kingdom of Ruberios, we were greeted by King Phillip and Queen Beatrice, then they said they would help my father to get better and they gave me the title of Tanjiro the Tengu knight. After the meeting with the king, we headed to our new rooms.

3rd person's P.O.V

Rokuta: You were brave, Nii-chan!

Tanjiro: You think so? 

Shigeru: Yeah Nii-chan, it was cool that you were praised by the king after saving Princess Flora." In a happy tone.

Tanjiro: Thanks, but I was still feeling a little anxious after that." With a sweat drop.

Kie: But you still hang in there and you were calm and focused. Me and your father would have been prouder of you." she said.

Tanjiro: 😁

???: HAHAHAHAHAH! YOU DID WELL AT THE GREETING YOUNG TANJIRO!"

Then Tanjiro looked at the hallway and saw Rengoku and he was not alone.

Tanjiro: Rengoku, Giyu, Shinobu, Kanae, Sabito and Makomo!

Shinobu: Ara Ara~ It's good to see you again Tanjiro.

Giyu: I hope you have been doing your training for a while.

Sabito: Good to see you again Tanjiro.

Makomo: *Smiles and nods*

Kanae: So Tanjiro, are these your family?

Tanjiro: *Nods* Yes, they are

Kie: So you guys must be Tanjiro and Nezuko's friends. *Bows* I'm their mother Kei Kamamdo. And this is my husband Tanjuro Kamado.

Rengoku: Is nice to meet you too, your son has grown up to be a great young man.

Tanjuro: Thank you for watching our two kids.

Demon slayers: *Bows* You're welcome.

Nezuko: And these are other younger siblings. Tekeo, Hanako, Shigeru, and the youngest Rokuta.

 Some of the kids hide behind their older sidings

Tanjiro: Don't worry, they are good friends of ours.

Shigeru: If you say so Nii-chan.

Hanako: You three look beautiful."

 All the girls want aw when Hanako comments on them. Then Hinata came from behind the Kamados.

Hinata: Sorry to break the reunions but, is time for me to take the Kamados to their rooms, they have a big day for tomorrow.

Tanjiro: What's tomorrow?

Celia: Tomorrow Tanjiro, you be teaching students swordsman styles. And Younger brother Takeo will be one of our new students in the class with the others.

Tanjiro: I see.

Rui: What about me and Mukago?

Hinata: You'll join Tanjiro as well in the training too.

Tanjiro and his family want to their new rooms then we see Tanjiro in his room looking at the ceiling thinking about Kanao.

Tanjiro: Kanao, wherever you are I hope you are okay.

(Next Day)

In the morning we see Tekeo wearing a academy uniform for the first time. He is wearing, a red and white top half and his lower half is black, he wears a black and white belt on his waist, and he has brown boots on his feet.

Celia: Tekeo, I know we haven't evaluated your academic abilities yet, but I was wondering, can you read and write?

Takeo: No but, my mom has been teaching me how to read. But I never studied writing before.

Celia: I see. Then, I'll tutor you! And I actually, I also have someone who is in the same position as you.

Takeo: Woah really?

Celia: Yes. Come to my research lab after school. It's in the basement of the library tower.

Takeo: Thank you.

Celia:  Oh. And...

Takeo: Yes?

Celia: Many children here are from royal or titled families, so...In the beginning, they may be a little...

Takeo: I understand.

Celia: What?

Takeo: I understand that some people don't like me because me and my family are outsiders. 

Celia: I see. But if have any problems, please don't hesitate to come to me all right?" Tekeo nodded. *Mind* "I am surprised that he doesn't care what anyone thinks of him and his family. I just hope some of the students get along with him and the new kid. 

She opened the door and they saw the teacher finishing his history class with everyone.

Teacher: Alright class, I'll be heading out. See you guys tomorrow.

As the teacher walks out of the classroom and bows at Celia. Then Celia and Takeo walk into the classroom, and Celia introduces Tekeo to everyone.

Celia: A new transfer student will be joining this class starting today. His name is Tekeo Kamado.

Everyone was whispering to each other that Takeo was the younger brother of Tanjiro who saved Princess Flora, but their some who still thought that he and his family should not belong in this kingdom.

???: "Woah! So you're the younger brother of Tanjiro the Tengu Knight?!

Then Tekeo sees one student who has Reddish-purple hair and eyes. Takeo nodded at his question.

Codié: Cool! My name is Codié Duckwood. And I hope Me and Tenko Shimura can be good friends with you.

 (And yes, Codié is one of my OC's)

Tekeo(Mind): What?! That name is Japanese! Is he a reincarnation from Japan?

Celia: Tekeo? Introduce yourself to everyone.

Tekeo: My name is Tekeo Kamado. And yes, I am Nii-san's younger brother. I hope we can get along with one another. I know I am lacking in many ways, but I hope that you will look favorably upon me.

Alphonse: It seems he can speak as well as a servant, at least."

 Every student laughs at Alphonse's comment about Takeo, except for Codié, Flora, and Christina. Codié just grunts at Alphonse. Then Celia told Takeo he well be sitting with Codié and Tenko.

Codié: Aw sweet!

The class starts their notebooks but Tekeo is having a hard time with this education, but Codié helps Tekeo and Tenko on what page are they on. Alphonse and his friend look at the three and giggle to themselves that Tekeo and Tenko don't know how to read a notebook.

(After math class)

Codié: So you two are going to miss Celia's lab?

Tekeo: *Nods* Miss Celia is helping us practice reading and writing.

Codié: I see. Then I'll see you two later.

 He waved at Tekeo and Tenko and then left. Tekeo and Tenko are heading to the research lab, Tekeo wants to ask Tenko about something.

Takeo: Tenko, I don't want to bother you but, your name, is that-

Tenko: A Japanese name, yes.

Takeo: And also why do you scratch a lot?

Tenko: *Scratches his eyelids* I don't know. Back in my old life, I normally scratch because of an urge to kill. But I guess in this universe is not that anymore.

Takeo: I see.

Tenko: I was surprised that your look and name are Japanese.

Takeo and Tenko were walking to Miss Celia's research lab when they spotted Rui and Mukago.

Takeo: Rui-san, Mukago-san.

Rui: Hay, Takeo. *🤨* Tenko right?

Tenko: That's me.

Tekeo: Excuse me but, what's going on in Miss Celia's lab?

Mukago: She and her helper are looking for the paper that she forgot.

Tenko was the first to knock on the door. Ceil opens the door but for some reason, she starts to yell at them.

Celia: Can't you read the sigh?

Takeo: Oh, we're sorry.

Tenko: We can't read.

Celia: *Realized*Tekeo? Tenko?

Takeo: We came to inquire about our private tutoring.

Tanko: but...

Celia: Yes! Well done on coming here. I've been waiting for you two. Great!

She acts with a smile. The four sweat drops as they know that Celia completely forgot that she told Tekeo and Tenko to come to her lab to tutor them. As they come in, they see her research room is a little messy but she has someone helping her clean it up.

Celia: I-It's a tiny bit messy at the moment. But I have a helper, helping me.

Senjuro: Hi. I'm Senjuro Rengoku. I'm helping Lady Celia find the papers at this moment.

Takeo: Nice to meet you, I'm Tekeo Kamado.

Tenko: And I'm Tenko Shimura, is a pleasure to meet you.

Senjuro: What! Tekeo, are you the younger brother of Tanjiro?

Tekeo: *Nods* "Yeah who did you know that?"

Senjuro: Your brother is a friend of my older brother Kyojuro.

Tekeo: Woah, cool!

Celia clears some space for her and the boys to sit down, then she and Iida tutor Tekeo and Tenko, well Senjuro clears some of the books. An hour later, Tekeo and Tenko finish their paperwork and then have tea time with the others.

Rui: I'm surprised that you two were able to get all of these right.

Celia: Did you guys do all of this in your head?

Tenko: Well, it was only multiply and division.

Takeo: We just need to know about the numbers.

Celia: Really? The only person in your guys' class who can do this is Princess Christina."

Tenko: Uh. I had no Idea.

Then the group talked about how everything had been going well in this academy, till it was time for Tekeo and Tenko to go back to class.

(With Tanjiro)

Tanjiro is with Hinata showing him around the place.

Hinata: And this, is the church of Ruberios.

Tanjiro: "Woah! Is huge!" In surprise.

???: Hay Hinata-sama, who's the newbie.

Tanjiro and Hinata look at a boy with white hair and has a short stature.

Hinata: Saare, this is Tanjiro Kamado, he's the one who saved Princess Flora. Tanjiro this is Saare, he's one of my group called the 10 Great Saints.

Tanjiro: I see. Well, is a pleasure to meet you.

Saree: Don't get too goody two-shoes with me. Just because you saved Princess Flora, that doesn't mean I would like you.

Then he leaves to go do something. Hinata just sighs at this.

Hinata: Sorry about him. He is just not used to you yet.

Tanjiro: I understand. Back then, I do have some people I work with who don't like me.

Hinata: Anyway, follow me, I'll take you where we practice students' swordsmanship."

 Hinata takes Tanjiro to the swordsmanship training ground. As they walk.

Tanjiro: Say Hinata, when we first meant, is your name-

Hinata: Japanese, yes. It happened when me, Vanessa and the others were still looking for Princess Flora.

(Flashback)

Christina: Where is my sister?

Female Chief: A boy with brown hair and wings just so happens to take her to his house at the east of the mountain forest.

Celia: Is she okay?

Female Chief: "Why yes, the boy is a kind fella." She explains.

As she was talking, Hinata and Vanessa were trying to force the masked man on who asked him to kidnap Princess Flora. But before they would find out who was it, the masked man died somehow, and now they have no clue who is behind it. Hinata and the others head to the east to find Flora. An hour later, they are in the forest searching for Flora and her saver until Ceile straps on a tread which alerts Rui who appears above them as everyone can see him in the air. Hinata can tell that the Arachne is standing on some threads, and what also surprises her is that he is wearing a Kimono. Christina was the first to speak to him but in a kind manner.

Christina: Hay! Where is she?!

Rui:...

Roanna: Christina! Be careful what you are saying!

Christina: Tell us where she is you freak!

Rui gives out a cold glare at Christina as the pressure around them gets heavier by the second. Hinata was watching the whole scene as everyone was on their knees feeling the intimidation. She decided to stand face-to-face with Rui as he spoke up but with a cold demeanor in his voice.

Rui: I don't know how you guys found this place, but I will not tolerate rude behavior here in the mountains. State your business or leave here at once.

Hinata: My name is Hinata, and these are my friends. Vanessa, Celia, Christina, and Roanna. Sorry for our friend's rudeness to you. Have you seen a little girl with light-purple hair?

Rui: You mean Flora?

Hinata: *Nods* Yes. We are her friends. She was missing from her home and we are trying to find her.

Rui: ...Follow me.

Rui guides them to the Kamado house. In the house, Nezuko is giving Tanjuro his tea medicine to make him feel better. Flora is doing the dishes with Kei to repay their kindness for their son Tanjiro for saving her. Suddenly the door opened and Christina was first to come into the room.

Christina: Flora!

Flora: Christina!

Flora stops doing the dishes and the two sisters hug each other.

Kei: Oh my. It looks like they found you Flora.

Celia: Thank you for saving the Princess on our behalf.

Kie: "Thank my older son, Tanjiro, his the one who saved her from that mask feen.

Vanessa: I see. So, where is he?

Nezuko: Onii-chan is sleeping right now, so he'll be awake soon.

Christina: ...I see.

(End of Flashback)

Hinata: Then your family introduced us to you guys and I was shocked that you and your family are from Japan.

Tanjiro: Woah! Well, I'm just happy that Flora is safe.

Then they reach to the swordsmanship training ground, Tanjiro sees the students training with their swords and shields with one another. Tanjiro then sees Tenko doing something else.

Tanjiro: Say Hinata, why is Tenko not doing sword training with the rest?

Hinata: Oh! He's doing magic training. Tenko asks Lady Celia if can he use a book to learn about magic.

???: Ah! Hinata is good to see you here today.

Tanjiro and Hinata look at the swordsman instructor as he comes up to them.

Hinata: Well is good to see you too and doing well.

Instructor: And you must be Tanjiro Kamado, *Bows* is a pleasure to meet your acquaintance.

Tanjiro: *Bows* Is a pleasure to meet you too.

Instructor: Tanjiro, would you mean showing me your sword skills? I want to see what you are capable of.

Tanjiro: Sure.

Tanjiro withdrew his black katana that he had with him,

Codié: Woah! Hey guys! Our teacher is challenging Tanjiro to a sword duel!

The students then stopped what they were doing and looked at Tanjiro and their instructor. Tanjiro is doing his Samurai stance which surprises some of them.

Instructor: Interesting.

All the students except for Tekeo, Tenko, and Hinata are shocked about Tanjiro's stance, and he's not using a shield. Hinata is the referee and starts the match. When Hinata said go, Tanjiro had already disappeared in a second, which shocks everyone.

Roanna: *😧* Woah!

Codié: *😧* He disappeared!

Flora: But where did he go?

The instructor is surprised that Tanjiro already vanished from his sight, but then...

Tanjiro: HINOKAMI KAGURA-FIER WHEEL!

Tanjiro appeared behind the instructor and sliced his wooden sword in half. Everyone is stunned that Tanjiro was able to beat their instructor in a second. Some of the students came up to Tanjiro and asked him many questions.

Male Student 1: How did you do that?

Female Student 1: Yay! What was that you did?!

Hinata: Everyone, please! Contain yourselves!

The students stand back from Tanjiro.

Tanjiro: Is called, "Hinokami Kagura".

Roanna: Hino What now?

Tanjiro: It means, Dance of the Fire God.

Codié: "That's sounds sick!" With sparkles in his eyes

Tanjiro: Hinokami Kagura is one first breathing styles that was made by my ancestors."

Female Student 2: "What is breathing style?

Rengoku, Giyu, Kanae and Shinobuthen arrive on the scane.

Rengoku: Breathing style is a technique for swordsmen in which a person controls their lungs.

Giyu: It's a type of swordsmanship that we used to fight in battle.

Tanjiro: For you to learn the breathing technique, you must choose at least one element to learn
