Two weeks after I made a promise to my brother.

Today's first period was a practical class.

In the training room.

"Kengo Mikazuchi-sama is here to observe our practical training class today! No disrespect!"

A large, muscular man stands next to the instructor.

He is the current Kengo.

"Gentlemen! It's not every day you get to watch the world's greatest martial artist! I'm going to give you a good squeeze today, so get ready for it!"

""""Yes!"""

The classmates looked at Kengo with respect.

"Well then, gentlemen! First, I want to know how good you are, so let's pair up!"

Usually, when this happens, there is an empty space around me.

"Hmph! You are as unpopular as ever, brother.

My brother Gaius came up to me.

"Oh, for heaven's sake. I'll take care of him."

"Oh, thank you. You're a good brother to have."

"Huh? Don't say anything funny or I'll kill you!

Anyway, we got into a kumite match.

"...... Oh shit, two of them are going to do kumite."

"...... retreated and retreated. I'm losing my life."

I don't know why, but our classmates started to pull away from us.

"Hey, hey, what's the matter with you guys? You're so close to the edge!"

Kengo comes up to us.

"Hmm? You guys look like you're up for it! Let's see some kumite [up close]."

Zawa......Zawa.......

"I don't think you'll ever be able to show the level of kumite that I, the best martial artist in the world, can see."

Leaving Kengo to his own devices, I go to face my brother.

"What are the rules? What's your weapon of choice?

Bare hands are fine. Ippon.

I'll be the referee. Let the match ...... begin!

Gaius kneads his fighting spirit.

Gao oo oo oo oo oo oo!

"What? Aura! Why such advanced technology!"

Dang it. ......!

"Seyaaaaah!"

Gaius, his body reinforced with fighting spirit, jumps toward me and kicks me.

I half-twist my body to dodge it.

Dogaaaaaaaaaaaaaaaan!

"What the hell was that? The wall shattered! And what's with the black hair that dodged it?

Gaius seemingly self-destructed.

""""Hey!""""

Pasch ......!

"Nwah! This time, it's the [Shadow Division]! Isn't that one of the deepest secrets of the martial arts!"

Gaius, who has transformed himself into three people, surrounds them and strikes them in rapid succession.

Pash! Pashipashi!

I hit all of his fists and kicks with my bare hands.

"Unbelievable! I can't believe he can move three alter egos at the same time, and at such super speed! Are you a monster?

"d*mn! I can't hit it! d*mn it!"

BOOM!!! ......!

Shoo! ......!

Doggone it. ......!

"[Shishi Shozoko], [Ryusui Teitai], [Mantis Ochiri]? They are all the secrets of a great fist!"

Each technique is reinforced with fighting spirit, and the weight and speed of each blow are off the charts.

"d*mn! If you can't hit one ......!"

Tang......! and Gaius gets away from me.

"What is that blond boy going to do next?

Gaius closes his eyes and opens his hands.

"...... right hand, magic. In his left hand, fighting spirit."

He puts a tremendous amount of them in each of his left and right hands.

"Ha,ha,ha...... don't tell me that boy is using [forbidden art]?"

"Oh, yes, I do."

"...... No, no way, that's an extremely difficult secret technique that no one has been able to use since Kengou 2000 years ago. What kind of a student are you?"

My brother puts his hands in front of his chest. to each other.

At that moment.

Go-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh.

A silver aura erupted from his body.

"Noooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo!"

Kengo, who was nearby, was blown up to the ceiling.

My classmates who were near the wall escaped, but they were trying hard not to be blown away.

I stood there, waiting for my brother to complete the move.

"This is truly a forbidden technique! A forbidden technique that allows one to combine magical power and fighting spirit to produce physical abilities that are greater than fighting spirit! I never thought anyone could use such an ancient art!"

"d*mn ......! You waited until I activated the jutsu!"

Well, well, well. Let's see what you've got.

Dang! ......!

We're in the air, fist bumping.

Gakiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiin!

"What the hell? Gone in an instant?

Boom! Bogg! Clang! Shubba ba ba ba ba! Giddyup, giddyup, giddyup, giddyup!

"I can't see! It's moving too fast for me to keep up with it! What the hell are those guys?

"d*mn! I can't believe that even if I use the forbidden arts, I can't get through to my brother in the flesh! You monster!"

"No, you too!"

After that, I parried all of Gaius' attacks.

My brother runs out of strength and magic, and he is stuck there.

"Ze ......! Huh ......! d*mn! We didn't win again!"

"Hey, good job. That was good. It would be better if I could get used to it so that I could activate the forbidden arts more quickly.

The younger brother tapped his hand on the ground in frustration.

"So, how was it? Kengo-san."

I ask Kengo, who is slumped down on the spot.

"Both of you! Will you be my apprentice?

Kengo was in front of us,

"Oh, no."

"No, thank you. I have a brother."
