Sound.
Looking back, the hints that lead to it seem to have always been right next to them.
Yet, this is something that is always there in everyday life.
It is often the case that the more familiar something is, the harder it is to realize.
And this is one of them.
The louder the sound, the more powerful it is.
Even if one cannot see, one can hear a sound and understand how powerful it is.
Even if one cannot hear, one can perceive it by the vibrations transmitted through one’s feet and by the mass of sound that hits the pit of one’ s stomach.
The taiko performances are designed only to teach everyone about the true nature of Oni.
It is a sound that resonates in the pit of one’s stomach and stirs one’s spirit.
Recalling the previous moments, every time Gouki moved, a stomach-churning sound and vibration shook the surroundings.
It had been hurled at them over and over again.
Not once was there such a thing as a silent attack.
It was not their nature.
Oni do not suit a silent and quiet attack.
“The Oni is not suited to stealth ……?”
“A quiet sword dance does not suit them.”
The two finally realized the true nature of the Oni.
But this was where the problem arose.
Understanding the true nature of Oni did not necessarily mean that there would be immediate results.
Yet, the two of them somehow knew how to proceed with the fight.
Tenda, who uses a katana, pondered how to make the most of the Oni sword dance he had been continuously studying.
Making loud noises with a katana.
Despite the fact that he had only figured out that much, he was able to create in his mind a completely different sword stroke than he had been able to do before.
Uchikage sits back and claps his claws.
If you are fast on your feet, then take care of your feet.
Without legs, he would not be able to display his speed, which he is so proud of.
He would have to use his arms too.
And then approach with banging noise.
Nothing can be done if he can’t get close enough.
Just how much can they catch their opponents off guard, and how should they move their feet?
Also, how to keep making noise even when moving?
Somehow they knew this, too.
“Tenda, are you ready?”
“Hell yeah I am.”
“You’ve changed your accent, …….”
“Just like an Oni, right?”
“That suits you.”
Like a real Oni.
When he was a little boy, he saw it in a picture scroll.
Just like Tenma-sama, whom they used to serve.
The two of them never actually saw the oni from the picture scrolls.
Neither of them had actually seen a real Oni battle, who knew the true nature of the Oni.
However, their instincts as Oni are telling them what to do.
They know what to do.
How to act, how to move.
Gouki looked at the two who had changed their posture, and muttered quietly that he had finally noticed.
Then he took a deep breath.
“……AAAAAALLLRIIIIGHT!!! That’s my sons!!! I’m going to get serious too!!!!! Bring it on!!!!!.””
A blast of sound that sounded as if it were five or six times the normal yell was hurled at the two.
But they are no longer fazed by it.
Even from Gouki who is a spectre oni..
He is many times more powerful than an ordinary Oni.
In addition to this, he also knows the true nature of oni, which means he should know what he’s doing.
However,
“Let’s go.”
“Yea.”
These two had no intention of losing at all.
Uchikage let out a loud bang! Then, emitting a loud sound, it gouged out the ground behind him and approached Gouki.
Just by making that sound, his speed must have been three, or even five times faster than usual.
Although Uchikage was a little surprised by this, he had many speed-oriented skills to begin with, so he quickly adapted to the change in speed.
Although he noticed the change in speed, Gouki could not respond to it at all.
The claw struck him directly in the abdomen.
A beat later, a gust of wind from Uchikage’s swinging arm blows around him.
(Will it break? !)
The attack was completely relying on brute force.
He was so focused on making noise during the attack that he was not thinking about the claw.
But strangely, the claw did not break, and only Gouki was blown away.
“BHHHUAAAAAAAH!”
“……Daaang……!”
He clenched his teeth unintentionally at the high-powered attack, but he was not harmed.
When Gouki was attacked, he put his strength into his stomach to prevent the claw’s attack, but it seems that he could not prevent it to the extent of his power.
BHUZUZUZUZU, sliding down and killing his momentum.
Then Tenda appeared behind Uchikage.
He was far away from them.
Gouki thought that the attack would not reach this far from that distance. ……
“Oni Sword Dance, [Turbulence Petal].” (Midarehana)
PWEEEE!!!!
A high-pitched sound was heard, as if a flute had been blown with all its might.
Tenda was also surprised with his eyes wide open, as if he had not expected such a sound.
But there was something else that surprised him.
He swung his katana and saw multiple slash coming from the tip of the blade toward Gouki.
The more blades that were split, the more slash there were.
He had used this technique several times before, but usually only a single slash was going toward the gouki.
Although he had used it while thinking that the name did not match the meaning, he finally understood what it meant when he saw it here.
Hearing the sound, Uchikage jumped out of the way at once, and while doing so, he also kicked up a rock in front of Gouki to make a blind spot.
This way, Gouki could not see the attack Tenda had unleashed.
Thinking it was a rock in his way, Gouki punched it away, but countless slashes came flying out of it.
He punches the sky with one of his arms, but there is no way he can outrun the slashes coming through the air, and he takes the attack as it comes.
“Ouch, ouch, ouch!”
“Damn, it’s hard. ……”
It can’t be helped. As expected from spectre oni.
But the attack was successful.
This made them feel happy and relieved.
They didn’t think that just being aware of the sound they were making would make such a difference to their attack power.
However, it was a happy coincidence.
They did not know what would change when they realized the true nature of the attack, but now they could really feel it.
They are strong, they are growing.
That’s what it seemed like to them.
Hmm?
Huh?”
They looked at their hands in surprise.
There had been a great change at this moment.
“…… evolved……?”
The status of both of them changed.
