[DanMachi fanfiction + not invincible + multiple female leads + original characters + respect for the original plot + worried about going out of character (I'll try my best to avoid it, if it happens, please let me know in the comments) (self-made cover)]

A wise goddess, seeking a cure for her child's illness, brings her kin to the "center of the world," embarking on her own "adventure" (heroic tale).

(Any resemblance to actual persons, living or dead, is purely coincidental.)

After accidentally stumbling into Nibelungen, Ivan realized he had entered the world of dragons. Fortunately, he had also acquired the complete set of characteristics and essence of the Outer God Super-Star Overlord from "Lord of Mysteries" with him. As long as he played the role step by step, his future was promising. Therefore, faced with the many problem children in the dragon world, Ivan felt he should do something. "Odin, is it? If the next nine supernovas all fail, then I'll switch to black hole explosions."

The canonical version awakens as a vampire in "Highschool of the Dead." In "Parasyte," he fuses with Parasyte. In "Kabaneri of the Iron Fortress," he devours Kabane. In "Jiojio's Bizarre Adventure," he becomes the ultimate perfect creature. In "Akame ga Kill," he becomes a super-dangerous creature at the top of the food chain. In "Fate," he becomes the immortal evil of humanity, living from BC to the present day. In "One Punch Man," he becomes the God of Monsters and fights with the Bald Man in the Cape from Earth to Mars. —The devilish version of Saya Takagi: "Scum, devil, shameless, die!" Joseph Joestar (jiojio): "I treated you as a friend, but behind my back you want to be my dad!?" Tohsaka Rin: "What is your relationship with my mom?!" Illya: "Dad, after this Holy Grail War is over, let's go flower viewing together."

Dragons have three... no, dragons have four heads! I am a descendant of the [Lord of the Star Deep], the mortal incarnation of the [Shepherd of the Sun], son of Aerion Targaryen of House Targaryen and Valerian of House Velaryon, lord of Dragonstone, younger brother of Aegon the Conqueror, and beloved of House Targaryen. I am the slayer of [corruption], the enemy of [fallen], the walker of [fire song], the harpist of [the song of men]. I am the [herder of dragons], the [priest of dragons], the [lord of dragons], the [rider of the sun]. Those who come after me, remember my name: Rhaegon Targaryen. So it was in the scribbled words. He is my brother, my arm, my heart, my shield, my sword, my sun. So it was in the neat, majestic words, followed by the beautiful handwriting: He is our brother, our dearest one. My beloved. So it was in the sharp words. He is a cruel executioner, a sinister black wizard, an enemy of the church, a heretic, a destroyer of nations, a villain, a bloodthirsty man, a heartless man, a ruthless man, a vulture deserving of the gallows, a barbarian, a devil despised by the Seven Gods... (some curse words omitted below) The secret tome says so. Prequel to the House of Dragons, the story of the Bloody Century - The War of Conquest - The War of the Church

Why would staying up all night playing cards lead to time travel? That's just...amazing!

Good news: This is a world of mental duels; with the Abhidharmakośa in hand, I don't know how I could possibly lose.

Bad news: Why are there only wolves...? Lucy...

Wolf Brother: I am Fenrir Wolf, v50, become our ally, and together we will restore the glory of the Kingdom!

What's it like to be a prince? Excellent looks, extraordinary talent, absolute power... Great, this must be my script for conquering the world! Hehe, I'm going to dominate the world! But when Faust picked up his dance partner's lost shoe, he suddenly realized... This is still a fairy tale world! But can anyone tell me... what does it mean to bring winter with beauty and give madness with song like "Snow White"? What does it mean to be a blood moon's generation of servants, the hunter "Little Red Riding Hood" who fights the Ancients? What does it mean to be the "Little Mermaid" who leads the deep blue flock and judges all living beings on land? .................. This fairy tale world seems too extreme. Dude, with these world-destroying monsters around, how am I supposed to dominate the world?! (Annoyed)

Lin You never expected that he would have to work after transmigrating.

Before transmigrating, I worked for a capitalist.

After transmigrating, I work for the gods.

Don't be fooled by the gods' kind and benevolent appearances; they can be more ruthless than capitalists when it comes to scheming.

Fortunately, in this construction project called "Project Great World," which was jointly funded by the gods, Lin You was required to do exactly what he did in his previous life—falsify history and make up stories.

We've already traveled through time, what else can we do? There's nowhere to call the police or ask for help.

They can only rely on the core technologies they still have to deal with the investors above them for the time being.

Utility, firefighter, scapegoat...

First, let's fulfill the job requirements, play the role of an employee well, maintain our impartial and neutral persona, and then incidentally gain some benefits for ourselves. Then we'll see if there's a chance to gradually make our way in the top.

At the very least, rewriting history is a lucrative business.

Si Jinkun, who traveled to the Demon Slayer world, shouted at the beginning: I don’t want to be a human being anymore!

He went completely crazy after arriving in the world of Demon Slayer

That shadow that has lingered for a thousand years—Muzan Kibutsuji! That pitiful creature who cowers in fear because of the curse, that false king who vainly seeks immortality!

All his struggles and blood ghost arts became futile jokes in front of Si Jinkun's ultimate body that combined the curse of the stone ghost face and the essence of countless ghosts!

He treats Wuzan as a high-end bun

It also forced the demons and the Demon Slayer Corps to join forces for the only time in a hundred years.

Many years later, Si Jinkun, who had already become a JO-level creature, looked at the world he had ruined and fell into deep thought.

In Waterdeep in 1372, Lion awakened in the body of a deceased orphan. Fortunately, he possessed not only a built-in system panel but also a unique summoning cheat. He could use the "concepts" he had acquired through various means to summon the projections of powerful beings from other dimensions into Faerun. [Slaughter] and [Survival] summoned the white-haired Witcher, who walked the line between man and monster. [Holy Light] and [Faith] summoned the Lightbringer, wielding the Hammer of Holy Light and representing faith and glory. [Dictatorship] and [Hope] summoned the unyielding monarch clad in power armor, shouldering the future of the human empire. As the Spider Queen, lurking underground, gazed upon the throne, and the goddesses of the night plotted to overthrow him, Lion and the powerful beings from other dimensions behind him would become the greatest variables! Unfortunately, at the very beginning, his...

My name is Imazumi Rinnaeus, and I'm a transmigrator.

As a transmigrator, I naturally came equipped with a golden finger system.

My system is called the Dream Performance System. As long as I complete performances according to the script, I can receive rewards in the form of "tags."

Those max-level attributes, talents, skills, and even tags for health and longevity look truly enticing.

However, this damn system took over a decade just to activate, and the first script it gave me left me speechless.

Because this script... isn’t something one person can complete alone. It requires the cooperation of several girls.

For heaven’s sake, even in open-minded Japan, what decent girl would agree to this kind of script?

...

"My name is Nakano Ichika."

"My name is Nakano Nino."

"My name is Nakano Miku."

"My name is Nakano Yotsuba."

"My name is Nakano Itsuki."

Today, they accepted an invitation from a certain "great system." In order to achieve their respective goals, they decided to seek out someone with the surname Imazumi and perform the script together.

It’s just that this script... is way too embarrassing...
