[Double male protagonists + no system + non-cool text + villain + both sharp and sweet]

P.S.: "Those with upright values, please watch with caution."

I woke up and found myself transformed into the villain Demon King Muzan Kibutsuji from the anime Demon Slayer?!

But now that things have come to this, in order to survive, Mo Yunchuan can only start to plan a way to save his life!

From now on, I will help anyone who has anything to do with the Demon Slayer Corps and try to win their favor. I must make sure my favorability goes to the hilt!! And I absolutely won't do anything stupid.

However, strange things also began to appear. Jiguo Yuanyi was resurrected and even wanted to get close to the Ghost King Mo Yunchuan. Why did he resurrect? This is a question.

Moreover, who is Kawano, who can transform between a cat and a human? Why did he appear? And why doesn't Mo Yunchuan remember him?

Then, why does this pair of bodies also have an unknown soul? Could it be that two souls simultaneously traveled through time into one body?

And...if being born is wrong, then will the choices we make also be wrong?

Why are there missing memories and extra memories in the brain? Why are there extra memories? And what will they become after they are reassembled?

What is sealed in the deepest part of his memory? Why doesn't he know? Why does he feel in danger?

Does the world really exist? Is it man-made? Can you accept it?

A mirror can reflect yourself, but is what is shown the real you?

Are you willing to destroy everything to achieve a goal?

What is good and what is evil? How can we distinguish and define them?

Are there perfect people in this world?

(Shadow clone technique + satisfying story + overwhelming power + easy-going)

Su Yuan, who was smashed into countless pieces by a dump truck, transmigrated. He had no system, no old man, and could not summon anything. What should he do?

That means I can only rely on myself; I am my own magic touch.

Marvel's Su Yuan: I wield the Phoenix Force, existing in the past and the future. I represent life and spirit. I am chaos, and I am immortal!

Zongwu Su Yuan: At the summit of Mount Hua, I am the peak; in the Hall of War Gods, I subdue the demon dragon!

Dragon Clan Su Yuan: The King descends from the heavens, his face contorted with rage and ferocity!

White Snake Su Yuan: Madam, I'm scared. There's a monk in front of me who's a gangster. He's tattooed and keeps shouting "Great Heavenly Dragon." Please protect me, Madam.

Su Yuan from the Imperial Heaven Realm: What do you mean? Am I the only one who transmigrated to the wrong world? Why don't I recognize a single person here?! Fine, fine, you all want to kill me, huh? Then don't blame me for losing my temper!

These are stories of Su Yuan clinging to his own powerful backer, climbing step by step to the top.

He was reborn in the world of Inuyasha, becoming the son of Toga, the older brother of Sesshomaru, and the Yami-ga.

Yoruichi calmly looked at Sesshomaru, whose face was filled with fighting spirit, and said indifferently, "Sesshomaru, do you also want to dance?"

Sesshomaru: "Enough talk, let's fight."

"Shoot him, Sharpshooter!" Nightfang whispered.

A streak of white light pierced the sky...

Reborn in the Clover world, the scene of the battle is full of excitement.

I became Yuno and Asta's sister.

There is a devil inside, a bit of tsundere, and a huge appetite.

Enter the black bull group.

…

It turns out I'm not without magic. Seal! Unseal! Merge the two into one.

The final condemnation of the fallen god!

Both good and evil.

Half angel, half devil.

Different gods.

[Scam System] + [Rebirth] + [Unparalleled Comprehension] + [Gold Finger] + [Development]

"That day, the Otsutsuki descended, and the Naruto world ushered in its true doomsday..."

"I should have killed him earlier. I thought I could change the predetermined future..."

Jiao Lu died, but he was reborn. After his rebirth, he traveled to Konoha Village, just wanting to kill Boruto while he was still young, but the cheating system made the opportunity slip through his fingertips again and again...

Just when he was feeling discouraged, the system gave him an incredible enlightenment, which made him, the last-place student in the class, instantly have an incredible enlightenment that allowed him to see through everything.

While browsing the library, Jiao Lu was surprised to find a special book with only one page, which no one could understand except him. This book was actually!

The altered plotline caused the Ten-Tails, which was supposed to be dead, to be reborn, and was used by the Otsutsuki clan to return to the ninja world. However, the savior Uzumaki Boruto, who was supposed to save the world, could not escape the control of Otsutsuki Momoshiki...

The world is on the verge of destruction, and the burden of saving the world falls on Jiao Lu alone. His companions who have been with him along the way died tragically in front of him. What should Jiao Lu do?

"If I could do it all over again, I would definitely choose to kill you, Uzumaki Boruto! Even if I have to become a despised villain..."

Mu Sheng, who just wanted to lie down, suddenly woke up and traveled through time and received a refining panel! In the human world, Mu Sheng: As long as I have no morals, no one can kidnap me! In The Smiling, Proud Wanderer, Mu Sheng: My sword is not weak! In Harry Potter, Mu Sheng: How can I be the Dark Lord? In the Naruto world, Mu Sheng: I don't care, I want to drive a Gundam! Refining Superman blood in the DC world, Mu Sheng: I don't eat beef!

As the colossal ship named Black Whale crossed the endless seas, what awaited them was the gatekeeper and the dark continent behind him... What? You're telling me the gatekeeper is Gol D. Roger? The dark continent is full of purple fruits that can awaken Nen abilities if eaten? What...? The Hell Rattlesnake is Kaido? The gas-mist-like life form A is Crocodile? The nurturing beast Papp is Big Mom? Iron Body is actually "Firm"? Finger Pistol is actually "Shoot"? Paper Drawing is actually "Flow"? Observation Haki is actually "Circle"?! Master, I understand! After the Black Whale survived the Great Battle, some died, some escaped, and Kuroro, who rewrote the ending and ultimately won, led the new Phantom Troupe, riding the Black Whale, and set sail! The New World? Isn't this the New World? What kind of extremely evil people are these? Aren't the spiders evil enough?! ...Know...

I'm Aizen, and I'm panicking right now. I thought I was at my peak from the start, unstoppable, but can anyone explain what happened to that big brother I remember as "Vongola I"? This doesn't seem like a pure Bleach world!

I originally thought that if I could just stay awake until the plot started and hypnotize myself together with Kurosaki Ichigo, I would be able to reach the pinnacle of my life. However, this doesn't seem to work in this unfathomable world, so I can only go to different worlds and act out various identities to accumulate strength and the power of heroes, so that I can once again become Lan Da in people's eyes!

No female protagonist + multiple worlds + trading

Here you can see emperors queuing to trade, and you can see gods selling their own blood.

Anything is possible here, as long as you can afford it!

Yu Hao: "Our shop adheres to the principle of equivalent exchange. I am not a demon who takes your soul; I am just a small businessman!"
