Marvel Multiverse System

"Hinokami Kagura – Thirteenth Form: Total Solar Cycle!"

"With this, I can say that I have mastered all thirteen forms."

Yuri looked at Akaza and asked:

"What about you, Akaza? Have you made any headway?"

Upon hearing Yuri's question, Akaza closed his eyes and smiled with indescribable enthusiasm.

"Yes… I have also reached the highest realm, the transparent world."

Transparent World is a special form of ocular extrasensory perception that alters their vision, allowing them to perceive other living beings as if they were transparent, only being able to see the inner workings of their bodies.

Potentially, one can use the power of the Transparent World to see inside an enemy's body as a way to predict and evade their opponent's attacks, as well as find openings for their own attacks.

They can see through the other person's body, thus observing the flow of blood vessels in the other person's lungs, the contraction of muscles, and the activity level of organs, etc., can be used to predict and perceive the opponent's actions.

The user's perception of quick and brief events is heightened, to the point where normally incomprehensibly fast objects can be perceived naturally, drastically increasing their speed of movement and reflexes.

[A/N: Yes, I know only Demon Slayers with the hunter's mark can use this, but, I want it to be like this haha]

Akaza practiced hard for over 130 years and finally achieved this ability after being killed for the thirteenth time by Yuri.

At that moment, Akaza smiled and looked at Yuri.

"Yuri Winters."

"You are truly the strongest swordsman I have ever seen."

"I have a good suggestion."

"How about becoming a demon too...?"

"The human body is nothing more than a burden. Life, time, talent, everything is so limited and insignificant."

"Yuri, tell me quickly… are you going to become a demon!?"

These thirty-three days of fighting left Akaza extremely in awe of and to some extent, obsessed with Yuri.

"Listen to me, accept Muzan-sama's blood! And then in 300 years, 200 years… No, maybe in another 100 years, you will be able to hone all your skills to the maximum! I'm sure your skills will be at the peak, in the supreme realm!"

"Unfortunately, I will have to refuse. A certain couple of training freaks would beat me up if I accepted." Yuri rejected the proposal.

"In return, I will show you the greatness of human potential, Akaza!"

Yuri put away his nichirin, crossed his arms in front of his face and shouted

"Third Gate, the Gate of Life, open!"

Opening three gates allowed Yuri's fighting spirit to overcome Akaza.

He clenched his fists copying Akaza's fighting style and faced him with a smile.

A human and a demon, the fighting spirit of both collided silently, and a new round of fighting, exclusively hand-to-hand, began!

---------

And so seventy days passed quickly.

Yuri eventually became or able to open and close the Fourth Gate during the fight.

At the same time, Yuri also reached the [Transparent World] supreme martial arts realm.

[A/N: Yes I know.]

Half a month had passed since he mastered this new level of power.

Yuri was happy to have finally gotten what he wanted thanks to Akaza.

At the same time, Yuri also reached a much higher level in his other abilities!

It was through Tsukuyomi that Yuri was able to have so much time to fight and improve his skills.

From Ninjutsu to Taijutsu, sword skills, to true fighting experience, he has reached a level that few others could achieve.

If he returned to Naruto's world, and someone tried to assassinate him...

Yuri can guarantee:

Even if Minato himself, known for his speed on the battlefield, came to kill him;

Yuri could easily match and defeat him.

After realizing what he had gained, Yuri smiled in satisfaction and looked at Akaza.

"Akaza, you have my sincere thanks, thanks to you I was finally able to master my skills."

"Although I don't like talking to demons much, this time, in return, I will help you reach the supreme realm."

That said, under Akaza's confused eyes, Yuri canceled [Tsukuyomi].

............

............

Real world

Just over thirty minutes had passed.

The cool moonlight illuminated the road at night.

The remnants of the fight between Yuri and Akaza were noticeable, as there were many holes and craters on the road.

Under the bright moonlight, Yuri beat Akaza to the ground.

"And you still call yourself a martial artist?!"

"You have been stagnant at the same level for over a century, why do you despise the weak so much?"

Yuri's violent punches fell on Akaza, who was completely unable to resist. He tried to return blows but Yuri always blocked or retaliated!

"Knowing pain, injury, and death is the driving force behind human progress!"

"To reduce damage, we hone our skills."

"To increase our lethality, we study different techniques!"

"Humans have improved themselves until now to live a better life, to survive!!"

"And you?"

Yuri stopped punching, grabbed Akaza's collar and asked angrily:

"You have practiced for over a hundred years, but you are still stuck at the same level!"

"Where did your training go?! Into the trash!?"

"Why is your level still stagnant?!"

"The limits of your body can no longer be surpassed, your martial arts are stagnant, and your life is being manipulated and toyed with by another…"

Yuri's eyes seemed to be able to look straight into Akaza's soul.

"Akaza! Tell me, do you really think you deserve to be called a fighter like that?!"

"You never thought... Why did you develop these martial arts so much!?"

Akaza, who was trying to break free from Yuri's grip, remained silent.

"To become stronger…"

"I want to get stronger!"

He responded unconsciously.

"But... why do you want to become stronger?" Yuri asked as he stared at Akaza

"Because... because... if I don't get stronger, I won't be able to bring my father the medicine."

At this point, he froze in place.

That's right, if I don't become strong, I won't be able to steal money. If I don't become strong, I won't be able to fight back when I face retaliation. I will be sent to the government to receive the criminal tattoo on my body.

If I don't get stronger, my seriously ill father will die.

That was 11-year-old Hakuji's only thought.

But his father still died.

After hearing about his son's crimes to get medicine for him, he committed suicide out of guilt.

[Hakuji, I'm sorry for causing you any trouble. But I didn't think about living long enough to make my son become a criminal. Please live this life with integrity.]

This is the suicide note his father left before he died.

But he didn't correct himself. He was tattooed with criminal tattoos and lived elsewhere, earning a living fighting on the street.

He thought his whole life would continue to rot like this, until he met them.

"You have good skills, become my disciple!"

That's what Keizo said after defeating him in a fight.

Just like that, he accepted him and Hakuji became his disciple. He was the only disciple in this man's dojo, before he had to go out and work for others to fill his stomach.

His master prepared a room, provided clothes and food for him. Of course, out of obligation, he had to take care of his daughter, Koyuki, who was seriously ill in bed.

Taking care of a girl who is seriously ill was very troublesome, but he had been used to this kind of trouble for a long time. After all, he never saw his mother and always took care of his father, who was also seriously ill in bed.

That was the happiest time of his life and he lived like that until he was 18. He fell in love with the girl he was looking after and his master agreed to let them get married.

And when he returned happily after paying respects at his father's grave, what awaited him when he returned to the dojo was... Hell.

His dreams, his happiness, his love, his master, everything he cared about was gone.

Disciples from a neighboring dojo who were jealous of his master poisoned the well. His master died, and... his beloved Koyuki too.

Filled with pain and fury, he killed every member of the dojo and developed a hatred for the weak.

He had promised to watch the fireworks with Koyuki next year.

He promised to become stronger than anyone else.

He promised to protect Koyuki for the rest of his life.

But in the end, he was unable to fulfill any of these promises.

He was later turned into a demon by Muzan Kibutsuji and lost his memories.

It turns out he lost his humanity and turned into a demon, still seeking to become the strongest. There was nothing else he wanted to protect. He didn't want to continue living aimlessly, but he did it repeatedly. A century of slaughter...

He killed more than 67 people with the Soryu style and stained his master's important style with blood.

The martial arts he perfected to protect his family... Have turned into a weapon for murder...

He couldn't help but start crying.

"Yuri... could you... fight me one last time?" Akaza asked while looking at Yuri.

Yuri smiled slightly and walked away from Akaza.

"Of course Akaza, we're going to have the best fight of our lives. Show me the humanity in you, your desire to protect those you loved."

"Very well, Yuri." Akaza stood up, as his wounds healed.

He got into the Soryu style fighting stance.

"I know I can't beat you, but I want to dedicate this last fight to my master and... my fiancee, Koyuki."

Yuri copied Akaza's movements, getting into the same position.

His Sharingan slowly rotated, showing that he was prepared to copy Akaza's fighting style.

"Don't worry Akaza, your master's style won't die. I swear on my life I won't let that happen..." Yuri promised as he looked seriously at Akaza.

"That makes me happy." Akaza smiled and advanced towards Yuri, for his last fight, his features now somehow looked... human.

Yuri smiled seeing this and moved forward as well, he had to admit that he had come to admire this demon a lot.

It can be said that even in the manga and anime, few of the demons were as incredible as him.

It wouldn't be bad to give Akaza a worthy ending.
