『OOC Warning + Chaotic Plot』

[Many OCs appear, enter at your own risk]

A college student who hasn't yet become a corporate slave appears to be eating cake on his birthday, but he's actually been away for a while.

My consciousness is hazy.

"Come, child, walk towards the light, and you will find the way."

He heard a voice guiding him.

"My child, I bestow upon you the title of Named Demon. You are a child favored by the gods. Your name is: Nelion Cossatis."

"The ability you possess is...world consciousness, and it will help you, child."

...

He transmigrated with memories of his past life, and he had no idea where he was. Someone had just told him that his current name was Nilian Cossatis, and that he also possessed a world consciousness.

This is... a time-traveling cheat? That's pretty good.

But why is he a beige slime?

Later, in this black hole, he met a fellow transmigrator who was also a slime—well, from a different country.

This slime is named Rimuru Tempest.

...

So, they continued walking forward together.

Nelian's original ambition was clearly to become a carefree, adorable, and gluttonous slime!

It's definitely heading in that direction... but I've encountered all sorts of different people along the way...

Wait, wait a minute? Why are you guys looking at me like that?!

Pirates are evil? The Navy is righteous?!

Haha, who knows? This idea has been changed countless times!

Only those at the top can define justice, and will justice prevail?

That's for sure, because only the victor is righteous!

...

Does the winner always prevail?! If I had a chance, I would want to change all of this.

As soon as the words were spoken, two moons appeared in the sky, and a golden lightning bolt struck straight down.

Xia Wu: No way, you're serious? (°ー°〃) I was just bragging.

A casual, boastful remark landed Xia Wu in the world of One Piece. Fortunately, the perks of being a transmigrator allowed him to survive in the dangerous pirate world.

Until one day, a blond man appeared, and the wheel of fate began to turn wildly.

"Boy, be my son, bear my name, and make a name for yourself on this vast ocean!"

"Huh? Are you sure?! Let me taste a liter of your blood first to see its power."

Whitebeard: "(ー_ー)!!"

[Legendary Whitebeard Newgate bloodline factor detected - refining earthquake power, the Creator of All Things System officially activated...]

Has it finally arrived?

[Earthquake Power + Overpowering Heavy Armor => Super Long Standby Earthquake Set]

[Burning Flame + Thunder Stone => Thunderfire Dragon Set]

...

[Detected that the Supreme Grade Sword Ace contains bloodline factors of Rocks, Shiki, Roger... , extract?]

Yes, yes, yes!

Hehehe, world, here I come! Are you ready?!

Is justice only served by the victor?

I am justice!

Celestial Dragon: Yes, yes, you're right!

Im: 6!

(Early relaxed daily life, later serious national career line) (single female lead) (later a lot of original self-design)

(Starting with master-level swordsmanship, farming, and conquest) After retiring from the military, the meritorious sergeant major Rice returned to the barren "Griffin Frontier" with his life savings to live as a wealthy free man. He wanted to stay away from the empire's conflicts and live a quiet life.

However, his "already awakened" transmigrator soul, and the [Pathfinder Panel] that was only activated upon his retirement, destined him to be anything but ordinary.

When Rice finds a dying werewolf girl burdened with a blood feud at her doorstep during a severe blizzard—the gears of this once-silent frontier begin to turn.

Faced with greedy inferior nobles, rampant monsters, and the empire's corrupt order, Rice calmly wiped his standard longsword.

"There's no other way. In order to get a good night's sleep, I have no choice but to turn this land into my empire."

The abyss has invaded, Earth has undergone a cataclysmic change, and the era of universal job advancement has begun.

Su Bai switched to a useless profession and started as the captain of the Fools!

Only when your level is high enough can you obtain all of the captain's abilities.

And so, the nightmare of the abyss began.

I don't care what it is, whether it's a hell dragon, a demon lord, or some abyss overlord.

They're all trash compared to my immortal captain.

If you want to invade Earth, you'll have to ask the sword in my hand first!

Amamiya Yoru accidentally transmigrates to a world where the myriad realms are just beginning to appear. Various monsters and characters from these realms are beginning to emerge. Fortunately, along with her transmigration, Amamiya also obtains a system called "Myriad Realities Role-Playing." By gaining fame through this system, she can draw various characters to role-play! Her first role-playing is Gilgamesh, the King of Heroes from the Type-Moon universe! King Arthur! Karna! Zhongli! and many other characters. Thus, Amamiya begins to role-play all sorts of characters, and the characters she portrays gradually become renowned throughout the world! (This leans towards crossover anime/manga; multiple anime/manga characters will appear later.)

A cultivator accidentally enters a crossover anime world and embarks on a journey into the God's Space (not the original). (Multiple female leads, including Yukinoshita, Ryo Yamada, Ryougi Shiki, and Ai Hayasaka)

Mission worlds (Fate, Akame ga Kill!, Naruto...)

(I didn't get the pacing right. There will be a lot of Yukino's scenes at the beginning, so I can only finish it with Akame ga Kill! I'll revise it later.)

Yu Ai, having traveled ten years, finally obtained a chat group. Actually, I'm a god-slayer; my specialty is fighting against gods. Frinina: I'm not the water god! What do you mean I'm now Rosef, leading the citizens to defeat the thunder god and the wind god? Fujimaru Ritsuka: I'm not a god either! What do you mean Babylon is a city of 100,000 people? Theresa: We Terra do have gods! What do you mean you want to fight Xi Bao for three hundred rounds? Su Chang: We have star gods here! What do you mean you want to usurp the power of "expansion" and ruthlessly expand the entire universe of beautiful girls? Melina: We have demigods here! What do you mean you want to elope with Lani? Kato Megumi: This is just an ordinary everyday world… wait a minute, what do you mean you found a demon and an angel? Today is another day of arguing with gods in different worlds.

The shackles of destiny, frozen for millennia, quietly shattered, and Tang Wulin and Gu Yuena unexpectedly awakened in a new era. Before the horn of the God Realm's return to nothingness had even sounded, the struggle between soul beasts and humans had already begun on the chessboard of a new era. When fragments of memory intertwine with the thorns of reality, can this destined lover break free from the constraints of time and space?

My name is Yi Ze, an ordinary student at Shuangxing City Superpower High School. I've always considered myself fairly intelligent and a decent student. But things started to change in high school. I wasted the second awakening guide stone my dad got me, and I became known as a good-for-nothing and a spendthrift. Until one day, everything changed again. A voice quietly appeared in my ear, "Want to become stronger?" "Hmm? ~ Yes." "Then start with time travel. Time travel is the only way for you to become stronger, and missions are the only shortcut to success. Young man, go to the endless dimensional worlds to find the path to power."
