[Ghoul World is complete]

Monster 8 World is in progress.

[Eating + Killing + Torture + Extreme Enjoyment + The entire main cast is devoured + Invincible + Symbiote + Bickering + Multiverse + Evolutionary Flow + No Mary Sue + No Female Lead + Dark Theme]

A top assassin from his past life was brought to the ghoul world by a system. He was given a symbiote called "Riot" at the start. The two shared a body, and fighting and devouring were the only meanings of his existence.

Riot: "Left! Tear him apart! His kagune smells really good!"

Nothingness: "Shut up, you brainless lump of slime, I'm aiming for your vitals."

Riot: "Eat, eat, eat! Eating will make you stronger!"

Void: "If you make any more noise, you won't get to eat anything next time."

(Also, the author doesn't rely on this for a living; it's just something to write in their spare time. 50% of the book's profits will be donated to help others, 20% will be given to fans as gifts, and the remaining 30% will be used to buy themselves a pack of cigarettes. I'll post about the good deeds I do in the comments section, so please don't be so malicious towards the author, thank you.) Also, there's no need to send gifts; just give the author a few likes to urge them to update. I only want to urge them to update.

[Warhammer + System + Decisive Killing + Infinite Evolution + No Female Lead]

"The Emperor created twenty radiant demigod Primarchs to conquer the daylight of the galaxy."

“And Makado, in order to protect that unspeakable darkness, created Wiz in the deepest part of the laboratory.”

...

Traveling through Warhammer 30,000, he becomes the most dangerous secret experiment of the Imperial Chancellor Macard, the "Prototype Zero" of the Maerorus Guild.

Wiz has no soul, no sense of pain, only a perfect killing body fused with unknown genes and yearning for flesh and blood.

And, a **[Devouring Evolution System]** from the void.

In this despairing universe filled with bombs, chainswords, and warp demons, Wiz doesn't need power armor because his skin is harder than adamantite; he doesn't need bolters because his bone spikes can pierce through Titans.

[Devour]:

Devour the Orc warlord alive—gain [Cell Regeneration] and [Infinite Strength]!

Prey on the Eldar Prophet—Gain [Time Warning] and [Faster Light Nerves]!

Chewing on the Great Demon Nurgle grants [Conceptual-level Plague Immunity] and [Immortality]!

...

At the end of the Great Crusade, the Horus Rebellion broke out, and the galaxy burned.

As the traitorous warlord Horus raised his claws, ready to kill Saint Gilles, the shadows suddenly stirred.

A claw covered in a void carapace caught Horus's heavy blow.

Wiz grinned, revealing fangs, and looked at the shocked Primarchs before him, letting out a hoarse, greedy whisper:

“Praise the Emperor… What a sumptuous buffet this is.”

"Uchiha of the One Piece World," "Marine Admiral," "Smoker's stepsister," "The Celestial Dragons' lifelong nemesis," "Is Sharingan + Ice Release + Devil Fruit a viable combination?" "Ancient Zoan - Snow White Wolf!" "The Navy's peak of handsomeness in 800 years!"

With the aim of hunting down the Celestial Dragons, he used a dual identity to rise through the ranks of the Marine Headquarters, becoming the youngest admiral in history!

Borsalino: Compared to that brat, we're ashamed to be called monsters.

Sakazuki: Although he's an ice-wielding guy like Kuzan, I felt this kid's burning sense of justice!

Kuzan: Compared to that, my fighting style seems incredibly crude.

Sengoku: He will be the future of the navy! A pillar of the navy! (Most importantly, his face boosted his recruitment rate by several points.)

Garp: I have a feeling... this guy will unleash a storm of a great era, just like Roger!

...

Ten years later, the Marineford War.

When the Sharingan's gaze fell upon Marineford...

Allen spoke softly.

"The winners don't care what the world is like, they care about how they make it..."

"And I am the victor!"

"Schrödinger's heroine," "decisive and ruthless," "ruthless and vicious," "arrogant? What kind of young person isn't arrogant?!"

It's time to show the world a fighting style that's no longer suited to this era!

The story takes place in the 42k era, after the fall of Cartier and Guilliman's awakening. The protagonist's stats aren't high, but his abilities are conceptually advanced. He starts by healing the sick and saving lives at the bottom of the hive, then becomes a space firefighter. He's either in a chaotic melee or on his way to one. The quack doctor will use his miraculous healing skills to protect the Emperor's loyal subjects. If life is the Emperor's currency, then Ivers is the one who mints that currency.

Saving people is awesome! Fighting is awesome!

Bring salvation and loyalty to a distant and dark future!

[Rating just came out!! It will gradually rise!!]

[Pure villain + pure evil + cannibalism + invincible + no system]

Kurokawa, a sickly man coughing up blood every day, has been surrounded by malice since birth because of the twisted lines on his back. His only sister, who loved him, was burned to death by the villagers while protecting him.

In his deathbed despair, Muzan, lurking in the shadows, offered him a way out.

The demon blood enters the throat, awakening the seven aspects of the Blood Demon Art.

Pride, envy, wrath, sloth, greed, gluttony, lust

This filthy world is disgusting!

I will judge your crimes!

[Isekai action anime] + [Sharingan] + [Invincible]

Hao Cang transmigrated into a two-dimensional anime series and became bound to a 'Popularity System'.

If a character's popularity ranking falls below the top ten at the end of the first season, a plot device will be used to force the character 'Haocang' to leave the show.

Those ranked fourth to tenth in popularity will be eligible to participate in the second season.

It ranks third in popularity, with a significant increase in the second season's storyline; conservatively, it could reach 10%.

Ranked number one in popularity, unlock exclusive character background modification privileges.

In order to prevent his character from being killed off prematurely, he had no choice but to constantly gain popularity, exchange for various props, improve his strength, and add more storylines for himself.

Soon, a powerful, imposing, and captivating villain was born.

........

Years later, relying on his own 'efforts' and 'talent,' Hao Cang, who had finally reached the pinnacle of the world, stood with his arms crossed, facing the main characters, and delivered his most powerful message.

"Do you... also want to dance?"

...

P.S.: "Despite being a supporting character, his popularity is excessively high," "The Sharingan in an isekai shonen anime," and "First place in the Uchiha Madara imitation contest."

Darkness descends, order collapses, humanity is lost... Wails of death resound, despair and terror descend! Hell is empty, the devils are here. Chen Chong knows that in this broken world, fists are power, and only when fists prevail can reason prevail!

In the misty sea fog, on the deck of the ghost ship, Hern Iheroa gazed into the distance, using a brass telescope inlaid with inhuman eyeballs, at a geometrically indefinable outline. He mechanically tore at the rotting fish flesh in his hands, stuffing it into the relatively neat slit in front of his skull, known as the "mouth." At that moment, only two questions occupied Hern's mind. First, when would he find a doctor? Second, what about the remaining 1,278 mouths on his body after he had eaten his fill—"So, doctor, is there... any hope for us?"

[Starting with the Eternal Eye + Devouring System + Decisive Action + Mastermind]

Having traveled through the Fourth Shinobi World War, Uchiha Gen awakens in the Uchiha Holy Land, possessing the All-Encompassing Devouring System!

Battlefield? No, this is his hunting ground!

He devoured White Zetsu to gain the power of Wood Release; he devoured Edo Tensei powerhouses to seize their bloodline limits; he devoured Tailed Beasts to control the power of the Six Paths!

Madara Uchiha: "My Eye of the Moon Plan... why is there a loophole?"

Princess Kaguya: "His power of devouring is actually greater than mine!"

Naruto & Sasuke: "He is the greatest crisis in the ninja world!"

While the Allied Shinobi Forces were still fighting for peace, Uchiha Gen had already looked down upon all living beings. His goal was to devour Kaguya, seize the power of the gods, and establish the Uchiha Empire, where he reigned supreme!

To crush everything with absolute power and end the chaos with iron-fisted measures.

This is his definition of peace!

I woke up to find a pair of bracelets.

Don't panic, the era of relying solely on one's father hasn't arrived yet, and the general manager's father is still alive.

I was eight years old that year, standing like a lackey.

Sean: Captain Golden Lion, what do you think of my song "Wu Dalang's Summer"?

Old Jin: Not bad, but it's still a bit worse than when I'm taking a shower!

He wanted to fleece the pirate crew for life, but the boss insisted on petitioning, and as a result, he never returned!

What if your company fails to go public? I heard there are now subsidies from the "Sky Island Fund" for startups, so what are you waiting for?

Sean: The last person to come for an interview was a Shichibukai. Everyone here is either a rare Devil Fruit user or a master of physical combat, or at the very least, a second-generation scion. Tell me, why should we hire you?

Niu Ma: I'm willing to work overtime for free, I strongly request to work the night shift!

Sean: Great, I hope you can start work immediately and enjoy the 996 bliss as soon as possible!

Freedom can be a fish swimming in the sea, or a bird soaring in the sky! The pirate stage awaits—come if you dare! The sea will teach every reckless dreamer a lesson!

Young man, this is your ticket to work all over the world, take it!
