So it has been a week since I have been adopted, and now myself, Kagaya and Amane, who was carrying little Hinaki, were going somewhere.

He said he wanted to enjoy time with his family on a walk, and he wanted to bring me because we were also going to see Urokodaki and his students.

Blue: So that's why you brought me?

Kagaya: Of course, I feel like you need to make some friends Blue

Blue: I mean...I guess you're right. I only have you and Amane as friends

Amane: It will be a good experience Blue, I'm sure you will become friends with Urokodaki's students

Blue: They use water bretahing right?

Kagaya: Yes, remember whem I told you that Urokodaki was the water Hashira?

Blue: Yeah but he is retired now, right?

Kagaya: Indeed

We reach a small house as Kagaya knocks on the door, we wait a bit until someone opens the door. It was Urokodaki himself.

Urokodaki: Oyakata Sama, you have arrived

Kagaya: Indeed, I hope you don't mind me bringing Amane and Hinaki

Urokodaki: Of course not, I see you have brought Blue as well

Blue: Hello Mr Urokodaki!

Urokodaki: Hello Blue, it is good to see you again

He welcomes us inside his home, and when step inside, we see three other kids. They were older than me and immediately bowed in front of Kagaya like everyone else does.

Urokodaki then goes over and introduces me to them.

Urokodaki: Blue, these are my students, Giyu, Sabito and Makomo

[Left is Giyu, Sabito is on the right and the girl in the middle is Makomo. I uhh....don't know why I have to clarify that.]

Sabito: Hello Blue

Makomo: Good Morning, Blue. He's so cute!

Giyu: H-Hello...

Urokodaki: Giyu and Sabito are both 10 at this moment while Makomo is 9, you are 6 now, right Blue?

Blue:

All:.....

Hinaki: [Giggles]

Kagaya: ^_^ You'll get used to it

After my glorious display, I walked forward and talked with the water Trio. This is what I shall call them and it seems like they don't mind, they actually liked it.

I quickly became friends with them, especially Giyu. I don't know why but me and him immediately had this link, he was however really weird.

Wait what was it called? I think Makomo said it to me?

Oh right! Anti Social!

Sabito: We try to get him to talk more, and to other people but it is a pain sometimes

Makomo: He is so negative that it almost feels like he will kill himself

Giyu: D-Don't say that!

Blue: [Le Gasp] Don't kill yourself! You still have so much to live for!

Before any of this could escalate, which it won't because we all know Giyu wouldn't resort to that, Kagaya wanted to see something.

Kagaya: How about we see the progress of Blue and one of your students, Urokodaki? I think it will be great to see what the future holds in this battle against Demons

Sabito: A Spar? Can I be apart of it?

Makomo: No! I want to fight Blue-Kun!

Giyu: I-I don't want to fight right now

Urokodaki: I assume it will be Blue vs Makomo then, are you sure you want Blue to fight? This will be his first proper training match with another Slayer.

Makomo: It is? I don't want to accidentally hurt him! Let's forget about it!

Kagaya: I believe Blue is ready, are you?

Blue: Yes I am! I'm ready! I worked so hard for the last uhh...two years!

I sat this, but I might lose though, Makomo is three years older than me and might have more experience despite me starting at a much younger age.

As I said, I only had about 2 years of experience and she probably had more actual spars. ._.

But I'm ready!

We all step outside, and Both of us are given wooden swords instead of real ones. We stand a few meters away and enter our fighting position.

Urokodaki: Ready?

Blue:

Makomo: I am ready as well

Amane: Both of you be careful, especially you Blue. You need to be extra careful.

Urokodaki: Winner is decided by whoever loses their sword first, now begin!

The match begins and it was I who made the first move. I immediately run over and aim a slash attack at Makomo, who ended up blocking it.

Blue: And now part 2 of my master plan! I slide kick her, taking her off her feet as I go for another slash but somehow in mid air, she blocked it?!

Makomo: You were saying :)

Blue: Oh nevermind, I guess I shouldn't have said that out loud ._.

Makomo: Why did you?

Blue: I thought it would throw you off and have you constantly thinking

Makomo: It was a good try

Makomo pushes me back with her sword and went for a spin kick, but I dodge miraculously and backflip away.

Makomo: Oh, you dodged it?

Blue: Of course! The spin kick is my speciality!

Makomo: It is?

Blue: Ye!

Makomo: Fair enough, I'm going to try now ok?

Blue: Okay!......wait what?

And just like that, she was already in front of me, I could see water appearing from her Blade and focused.

Makomo: Water Breathing First Form: Water Surface Slash

She went for a slash but I just about avoided it, but then, she already had another technique ready.

Makomo: Second Form: Water Wheel

She flipped vertically and spinned in a well....a water wheel, but I quickly recovered and countered with my own second form.

Blue: Galaxy Breathing Second Form: Spatial Storm!

I use Spatial Storm to clash with her water wheel as I unleashed about three strikes. My power was just about enough to put her off balance from her attack, so then I use Azure Blade as my next attack.

She did block it but it still sent her to the ground.

Blue: Are you okay Makomo?

Makomo: Yes I'm good, that wasn't bad.

Makomo walks over to me, and sends her slashes at me. I can tell I was slowly losing this battle, as it took everything I had to keep up with her, and I can tell she still had more.

But so did I, it seems I will have to use it!

I wonder how Kagaya will feel about this?

Blue: Alright, now I think it is time for me to claim my win

Makomo: Really? When we both agreed that you are losing, what special move do you have left?

Blue: Something I shouldn't be using!

Kagaya: Hmm...wait....oh no

Amane: What's wrong?

Kagaya: He's going to use that form...I don't agree with it because I only explained it once. And even though he hasn't tried it before, something tells me that I should trust in what he does

Amane: Kagaya, what is this-?

Blue: Galaxy Breathing Fourth Form! Galaxy Burst!

I spin my sword and bring it to my side with it pointing at the ground  a shockwave was heard and seen by everyone. This same aura was also surrounding my wooden sword.

Sabito: What is that?!

Urokodaki: So this is Galaxy Breathing

Giyu: T-That aura!

Makomo: What is that?

Blue: This is my final attack!

Now, I feel much stronger and faster than before, and I use this temporary power to quickly win the fight. I didn't want to spend too much time in this, so I watch as Makomo wasn't able to keep up with me.

I knock her back, then quickly deactivate Galaxy Burst. I catch Makomo before she can fall down as her sword was already on the floor.

And that's how I won using power I shouldn't be using now!

Because I'm not alright in the head! :D

Makomo looks ar me and I notice her face was red, maybe she is embarrassed that she lost to a boy three years younger?

Or....she is unwell!

Nah, it's probably the first one.

I help her stand and apologise for making her feel embarrassed in the fight.

Makomo: E-Eh? I me-mean yeah I was kind of embarrassed because of that

Urokodaki: Makomo, it's okay to say the truth

Makomo: W-What are you talking about Urokodaki sensei?!

Urokodaki: Don't worry, I see it all right now

Makomo: N-No you don't!

......What is going on?

Kagaya: It's amazing to see Blue use the 4th Form. I only explained it once, and I wasn't going to have him learn it yet as it was dangerous. But he tries it anyways, I'm not even sure if he was practising it in his spare time, but it's impressive.

Everyone moved on from that as they congratulated us for our good fight, I mean she was going to win.

Blue: Makomo, I just want to let you know that you would've won if I hadn't used my 4th form, remember that

Makomo: I can tell, that was a big surprise and switch up. It shows that you have something to use if you ever find yourself in something tricky.

Blue: Y-Y-Yeah!

Great....I was feeling the pain again in my chest. I quickly take out my medication and eat it.....huh...I'm actually getting used to the taste.

I was told by Kagaya that the 4th form slowly accelerates my heart and forces me to use my medication. I look over and can tell that the Water Trio were confused by this.

I was willing enough to tell them, but Urokodaki said he will explain to them after.

Urokodaki: Aren't you going to see someone?

Kagaya: Ah yes, I was going to visit him on his recent success

Blue: Oh, who is this man of success?

Kagaya: You will see, let's go Amane

Amane: Right

We were on our way to this other person's house that Kagaya mentioned, and while on the way he looked at me with worry. Now that's something I have rarely seen, because he was usually calm.

Kagaya: Blue...are you okay? After using the fourth form?

Blue: Oh it's about that....don't worry, I will be alright!

Amane: Blue, you need to be careful more! I heard you weren't going to learn that form from Kagaya yet! But...I am glad you are okay as well.

Blue: S-Sorry Amane....

Amane: It's okay, Blue. Just don't try to prove yourself everytime

Kagaya: Do not worry Blue, it shouldn't do that when you begin to master it. We won't start training for it just yet, but soon we will as you have the basics down.

Blue: Yeah, it felt really natural, but it was hard to hold!

Kagaya: That is normal

We noticed that it was getting dark soon, and quickly make our way to the place of another Demon Slayer. Kagaya knocked on the door, and out came this really tall guy!

He looked about the same age as Kagaya though, lucky genetics?

???: Oyakata Sama! You're here! Amane-Sama as well!

He bows in respect and then welcomes us inside.

Kagaya: Thank you, Tengen

(I can't find young pictures of Tengen or his wives so....wait until Blue is 14 when everyone is of canon age)

Tengen: If I may ask Oyakata Sama, who is this boy?

Kagaya: This is Blue Light, a Demon Slayer in training, he is only six and is allowed to call me by my actual name. I have given him permission, and you can also call him "Blue" as well since he prefers to call people by their first name

Tengen: Ah, how flamboyant of you! We shall become friends!

Blue: Cool! You're so tall, Tengen! Like really tall!

Tengen: Thank you, Blue, I can tell we are to become very good friends, dven if you are 8 years younger!

Blue: So you are the same age as Kagaya?

Tengen: Indeed! But he is even more flamboyant than me!

Blue: I believe that!

Tengen: And I see you have even brought the little one as well

Amane: I felt like going outside and taking Hinaki with me, also congratulations Tengen

Blue: Congratulations?

Kagaya: Tengen is going to become the Sound Hashira soon

Blue: EEEEH?! REALLY?! That's so cool! You're cool!

Tengen: I'm not cool, I'm Flamboyant!

Blue: Flamboyant!

Tengen leads us deeper into his house, and then takes us to the living room. Inside were three girls around his age.

???: A-Ah, I didn't see you Oyakata Sama!

Kagaya: It's ok Suma, how have you all been?

They all say they're ok and looked at me in surprise.

???: Hey Tengen, who is this kid? And the one carried by Amane-Sama?

Kagaya: Right? This is my Daughter Hinaki, and this is Blue. He is a Demon Slayer in training.

There was a silent pause and I wondered why, that's when Amane slightly nudged me and I understood what I had to do.

Blue: O-Oh! Uhh hello there! I'm Blue, and I'm 6, and I'm a Demon Slayer in Training! I'm strong though! I-I think....

Suma: H-He is so cute!

The same girl that didn't realise Kagaya was here, think her name was Suma, suddenly ran over and hugged me tight.

Why am I suddenly struggling to breathe? Help, please, someone? ._.

????: Suma! Stop! He can't breathe!

Suma: [Releases Hold] O-Oh! I-I'm sorry Blue!

Blue: It's okay! I....just saw the whites of the Heaven Gates ._.

Suma: A-Ah! I almost killed you!

Tengen:....Anyways let me introduce you to these girls, they're my future wives!

Blue: Oh okay

Kagaya: Same reaction to when I told him about myself and Amane....how amusing.

Tengen: The girl who just hugged you is Suma she is 9. The one who told Suma to stop, her name is Hinatsuru and she is 11. And finally there is Makio who is 10

Blue: Hello There! I'm six! Well, age wise, my name is Blue....w-which I already said.

Hinatsuru: [Smiles] We are aware, Blue

Makio: Wait he's 6? That's pretty badass! You must be close to fighting demons!

Suma: M-Makio, he is a little boy, he is still training!

Hinatsuru: It still is amazing that he is training at that age

Blue: I actually started when I was 4! :D

All: WHAT?!

Tengen: Now that is flamboyant!

Kagaya: Yes, Blue started at an age no one expected him start at, but I could see the potential inside of him

We all had a talk with Amane and the girls talking, while I listened to Kagaya talking to Tengen about his position as a Hashira in the future.

I had Hinaki in my arms as she sat on my lap, I was next to the two boys as Kagaya also asked if we could stay the night.

Tengen: Of course Oyakata Sama! It's already dark and there could be demons lurking around, so I am absolutely fine with it!

Amane: Thank you Tengen-San, that's nice of you, especially because we have some tired ones here

They all looked at me and Hinaki, as we were both ready to sleep. Well Hinaki was I was just about wake.

Blue: W-Wha? Tired? I don't know what you are talking about?

As soon as I said that I fell backwards asleep with Hinaki on my chest.

....Okay maybe I am tired.

Girls (Including Amane): So cute!

Tengen: I should have a spare room for him

Kagaya: No, that is fine, the four of us can share a bed

Hinatsuru: Are you sure? We can give Suma's bed

Suma: W-What?!

Kagaya: It is fine, Hinaki looks really attached to him

Amane: I hope this doesn't become an addiction, for all our children if we get more

(Oh you're so wrong Amane :D)

By the way next chapter will be a 2 year timeskip so Blue will be 8 at that point.
