In the G.O.C's castle, G.O.C is talking with Kokushibo about something.

Kokushibo: You want me to train someone? Why?

G.O.C: Well see. Me and the other Gods and Goddesses are having a hard time with this young one's life. And is a real shit show.

Kokushibo: And who can that be?

G.O.C: First, I have a friend who will help this new hero. And second, He should be here with the boy any minute now.

The portal pops out of nowhere with two figures. One was a hooded figure, and the other one as brown hair and red eyes.

Keyaru: Where am I? Who are you guys? And why am I here?

???: Calm down. And let my boss explain.

Kokushibo: Is this the boy you were talking about?

G.O.C: *Nods* This is Keyaru. And on his birthday, he will be a hero. And, we are going to train him to be prepared.

Keyaru: Me? A hero? And you guys will train me? Why?

???: Because we saw your future as a hero and you need to get stronger!"

Kokushibo: What happened in his future?

G.O.C: *😓* Um... That's a story for another time. And I'll tell you this, it's f**king nuts.

Kokushibo: ...I see

???: Anyway Keyaru, you need to train so you'll have a better future.

Keyaru: Really?

???: Yes, really.

Kokushibo: But why am I here for?

G.O.C: I'm glad you ask my six-eye Samurai demon compadre. I know in your universe; that you used to be a Hashira that can teach people how to use total concertation. So, I need you to teach him how to use it and Your moon breathing after the teacher is done."

Kokushibo: "I understand, I just hope he can learn it at least a mouth."

G.O.C: I'm sure he will.

Teacher: "Keyaru, are you ready to get train?"

Keyaru: *Sign and nods*

Teacher: Good. Now take this and put it under your sleeve

Keyaru: What is this?

Teacher: It's an am blade called Kakureta. Put it under your sleeve and put the ring in your thumb. Put the sting attached to the ring with your thumb to activate it, and do it again to put it back down.

Keyaru activates and de-actives his blade.

Keyaru: Oh! I see!

Teacher: "Use it on that training dummy."

Keyaru rushes and activates his blade and stabs the dummy in the head. And Kokushibo is impressed by how Keyaru is a quick learner.

Teacher: Excellent! You can also use it as a grappling hook.

Keyaru: A What?

Teacher: I'll show you. Point your Kakureta at the dummy.

Keyaru: Like this." Points at the dummy.

Teacher: Yes, now push that trigger on the side of Kakureta.

Keyaru: This one?

Keyaru pushes the trigger on the blade to grapple with the dummy and brings it towards him.

Keyaru: Woah!

G.O.C: Awesomeness!

Kokushibo: What else it can do?

Teacher: "You can also use it on something heavy to bring yourself towards it."

Keyaru: "Like this?"

Keyaru fires the blade on the wall causing him to grapple toward the wall and hit his face on it.

Keyaru: *In the wall* OUCH!

Kokushibo: "You okay kid?"

Keyaru: *Pops out of the wall* Yeah, I'm fine.

Teacher: Good, work on that. Now time to give you this.

Keyaru: Woah! What is that?

Teacher: It's a shotgun called Osoroshi. Use it on the dummy.

Keyaru aimed at the dummy and shot until there was nothing but stuffing.

Teacher: Subarashii! Subarashii! Now, one weapon for you to use.

Keyaru: Woah! A sword?

Teacher: Yes. It's called Aka no Kishi."

Keyaru holds the sword up.

Teacher: I'll teach you sword technique this will take a while.

(Time skip...)

The sky was dark and it began to sparkle. Keyaru was tired and sweaty because of all the training.

G.O.C: "Allllright, now is your turn Kokushibo."

Kokushibo: *Inhale and Exhale* Alright then, I hope you're ready to learn total concertation and my moon breathing techniques.

Keyaru: If that's what it takes to be a hero, then come at me with everything you throw.

Kokushibo: *Smiles* I like your spirit kid. But let me tell you how to do total concertation and breathing styles. For total concertation, the user must concentrate, relax their upper half, and brace their lower half before taking a long breath. There can not be any wasted movement during its application in combat, and this makes it difficult to master.

Keyaru: Seriously?!

Kokushibo: *Nods* And as for breathing styles, they are swordsmanship styles that make use of an esoteric breathing technique.

Keyaru: How many breathing styles are there?"

Kokushibo: "14. And some were made by my brother a long time ago.

Keyaru: Wow!

Kokushibo: Now then let's get to work.

Keyaru: Right. Say, is okay that can call you sensei?

Kokushibo: I don't see why not.

(6 months later)

Kokushibo's special training has put Keyaru into the must hellish training that makes Keyaru want to throw up. G.O.C and the teacher are feeling kinda bad that Keyaru has to go through all that. And Kokushibo is starting to like Keyaru as he is like his own son. Keyaru was now exhausted and sweaty.

Kokushibo: I think we're done for the day. Get some rest, and tomorrow I will teach you my moon breathing.

Keyaru gives a thumbs-up to Kokushibo and then faints

G.O.C: Ara~ I know their training can be hard, but not like this. *Giggles*

Teacher: Haha, well that's how they train their pupils for ya.

G,T: Hahahahahahahahahah.

(The next day)

Kokushibo: Your break is over, now is the time to learn my moon breathing forms.

Keyaru has been practicing with Kokushibo to learn his Moon Breathing forms. This was hard to do 100 times, but now he has succeeded. And now he's doing the second form of moon breathing, then the third to sixteenth form.

Keyaru: Moon Breathing: Sixteenth Form-Moonbow, Half Moon!

Makes downward crescent slashes.

Kokushibo: *Small smile*

Keyaru: *Putting up his sword* "Was I doing it right?"

Kokushibo: *Nods*

G.O.C: *Claps for Keyaru's approval* I am impressed. That was really outstanding training and experience.

Teacher: "And now drink this."

Keyaru: What is that?

Teacher: It's a potion, it will give you strength.

Keyaru grabs the bottle and opens it then drinks the potion until it is empty.

Keyaru: "Woah!"

G.O.C: Keyaru, how do you feel?

Keyaru: I feel like...a real hero!

Teacher: "Yes, you are!"

Kokushibo: *Nods*

Keyaru feels something on his hand, it was glowing and a symbol appears on his hand.

Kokushibo: Is that?

G.O.C: Correct! Keyaru's birthday came and now he's a hero."

Keyaru: What kind of hero am I?

Kokushibo: I was wondering that as well.

Teacher: You'll find out on your own. But right now, you'll need to return back to your village.

The teacher goes inside of Keyaru like a ghost.

Kokushibo:!

Keyaru: Wait! Why did that?

Teacher: (So you can have company)

Keyaru:!

G.O.C: Say, Kokushibo.

Kokushibo:?

G.O.C: I want to give you something for your own journey, so hold still.

G.O.C gives Kokushibo some awesome demon wings and magic.

Kokushibo's demon wings

Hellfire elements

Darkness elements

Illusion skill

Teleport skill

Kokushibo: *Looking at himself*

Keyaru: Wow! You look cool sensei!

Teacher: (Agreed)

Kokushibo: What does it do?

G.O.C: For Hellfire elements, point your hand at the dummy.

Kokushibo: Like this? *Pointing at the dummy*

G.O.C: Yes. Now say, Hell blaze.

Kokushibo: *Inhale and exhale* Hell Blaze!

Then the hell blaze burns the dummy into nothingness.

Kokushibo: Woah! Now I see.

G.O.C: Now for darkness elements, say Never ending nightmare.

Kokushibo: *Close his eyes then opens them* Never-ending nightmare!

Then the area became dark then lots of hands came out of the shadows and eradicated the dummy.

Keyaru: Now that's insane!

G.O.C: I know right? Anyway, you can also use Endless Nebula to make your opponent come closer to you.

Kokushibo uses an Endless Nebula to bring the dummy to him and then slashes it.

Teacher: (Nice)

G.O.C: Alright, time for you guys to go on your adventure. Good luck.

Ko, Ke: *Bow their heads* Thank you for everything you have done for us.

G.O.C sent Kokushibo and Keyaru to near Keyaru's village.

Keyaru: "So you're not coming with us?"

Kokushibo: *Shank his head* I want to go on my own journey. And if I go with you to your village, your people might get scared of me.

Keyaru: True. Then I hope we can see each other again someday sensei.

Kokushibo: I'm sure we will.

Kokushibo and Keyaru shank hands.

Teacher: (Good luck out there)

Kokushibo: You too.

Kokushibo and Keyaru want their different ways.
