I'm a time traveler and a complete 2D otaku. My lifelong wish is to spend the rest of my life with a paper-faced wife, while also saying "no" to 3D women. Well, it seems half of my wish has come true. One day, I was pulled into a mysterious chat group. Glancing at the member list, I fell silent. [American Scythe]: Just blew up a building. If any jerk dares to say anything again, I'll be the next one to go. [Devil Kinniku Rin]: Damn it! I've spent all my gems this month! Anyone got a way to get some money? Urgent, waiting online! [Herrscher of the Rice]: Tonight's dinner is tempura, Kiana... Oh, sorry, I sent this to the wrong person. [Marin]: Ahhhh! Anyone got any new slimy girls? Such love! ...Looking at this group of friends, all with different styles, but all my wives from my past life, I fell into deep thought again. Wait, isn't this a "2D Beautiful Girls Chat Group"? Why was I, a man, dragged into this?

Lin Xuan is famous all over the world as a plagiarist in a parallel world. He is hailed as the father of modern entertainment. However, no one knows that he has to be on guard against assassinations every day by these characters who come out of his works!

Misaka Mikoto: "Lin Xuan! Explain to me what the Absolute Ability User Plan is all about! Why do you have to torture me with this kind of plot!"

Tokisaki Kurumi: "Even if it's Lin Xuan, I will never forgive you for letting me bear all this!"

Akame: "So, the tragedy of our night raid was all your work?"

Altria: "So, my fate has always been in your hands?"

Lin Xuan: "Everyone, listen to my explanation! Listen to my explanation! This is all a misunderstanding! A misunderstanding!"

Travel through a world invaded by disasters and awaken the sign-in system of all worlds.

He thought that signing in in this world and obtaining the power of a Ruler of Reason, which was enough for him to protect himself, would be great enough.

Unexpectedly, he was selected by the dimensional chat group and got the opportunity to sign in to other worlds!

[Ding! Congratulations to the host for signing in to the Genshin World and gaining the allegiance of the Heavenly Principle and the Four Shadows of Heaven.]

[Ding! Congratulations to the host for signing in to Demon Slayer World and obtaining the perfect version of the immortal body, which cannot be erased by non-rule levels.]

[Ding! Congratulations to the host...]

Sign in to all realms, strengthen yourself, establish destiny and reverse entropy in the gradually collapsing world.

I originally wanted to head towards the end of the trees and the sea, but I found that I met countless beauties in the process.

Kasumi no Shi: "Tsk, what an unlovable leader!"

"You left a deep impression by being a hero saving a beautiful girl, but now you want to just walk away after you've been seduced?"

Eriri: "Damn it! I was here first, and the twin tails were supposed to increase attack speed! Why don't you come up and attack!"

Esdeath: "This man is stronger than me. I can't match him in terms of strength, but I must conquer him in other aspects!"

Lei Movie: "He saved his sister, if he wanted to..."

Gu Chuan, who traveled to the world of Zongman, awakened the ultimate power called [Analysis of Everything].

Thus, a dimensionality reduction-style cognitive crushing began:

When his best friend Toosaka Rin was still proud of the gem magic that had been passed down in his family for a hundred years, Gu Chuan created a new system of "energy opening" and "concept resonance".

When his best friend Esdeath regarded her ability to control ice as absolute power and looked down upon all living beings - Gu Chuan only observed for a moment, and then casually demonstrated to her the true power of freezing "concepts" and freezing "laws".

When his best friend Lei Dianzhen was still conceited about his "Unthinking Sword", believing that he had reached the pinnacle of thunder and lightning authority - Gu Chuan transformed the sun and the moon into the palm of his hand, evolved the five elements of thunder, and recreated the earth, water, fire and wind, making this Inazuma's Thunder God start to doubt for the first time that he might... be a fake Thunder God.

He traveled through a parallel modern world. He traveled through a prosperous ancient dynasty transformed by a time traveler. When he was inexplicably transported through time for the third time, the audience in the live broadcast room turned out to be everyone in both worlds? Knowing many unconventional and magical skills, he simply chose to ignore it.

My name is Ash, and my goal is to become the world's number one Pokémon Master.

And the opponent I will face is...

Xiao Mao is a strong rival of a mysterious old man named Qinglu who once became a champion in a parallel world.

Lan is a mysterious girl who travels from a world called Blue Star and owns a real Ditto.

At the beginning, there is an invincible Gyarados who is born to be a king, and his target is Misty, the gym leader of the world's number one water-type king.

Brock, the future world's number one Pokémon breeder, accidentally awakens the Eye of Analysis, and can automatically generate the best Pokémon training plans in his mind.

Huang, a shy girl, is protected by Beedrill, an invincible knight with the power of Evergreen and a spirit of gold.

Xiaoyao, the Fengyuan dancer, who integrates the memories of the Pokémon Ruby and Sapphire worlds and possesses a physique comparable to that of a Super True Rookie.

Xiaoguang, the daughter of a wealthy family, once traveled through time and space and returned from the Xicui area.

Alice, the true dragon messenger who possesses the power to control dragons.

Princess Serena of Carlos, who owns the Perfect Life Simulator and is dedicated to finding the most perfect life.

Joined the chat group and can communicate with the parallel world's full-level self, the Alola daughter Liliae

…

As for me, I started with a Pichu that seemed to have arrested evolution, and a Froggy that wouldn't produce Poké Balls.

You ask me what I should use to fight?

Sorry, I think I can see the barrage.

Moreover, the barrage called me the protagonist.

Quit the band and become a star god?!

Baili, who had traveled to the world of Zongman, decided to create a few Destiny Envoys with the help of the system.

However, the 'Starry Sky Train' that the system had snatched away kept receiving 'signals' from another world.

then--

Chaos Expansion: Clear the maze in the world of "Di Mistake"!

Chaos Destruction: Rias from "High School" becomes a Commander!

Chaos Harmony: Form a band for life, and then crush and destroy creation!

When the fate of chaos flows through planes such as "Hokei", "God Slayer", "Black Bullet", and "Azur Lane", everyone feels the glance of God!

Baili has only one explanation for his fate: what's yours is mine, and what's mine is still mine!

On the day of my car accident, something strange popped into my head!!! Yukinoshita Yukino: Hikigaya-san, stop what you're doing or I'll call the police. Yuigahama Yui: Hikigaya, you're actually doing this to me!!! Kato Megumi: Hachiman-kun, this isn't okay~ Kasumigaoka Utaha: Junior, you can't do that. Sawamura Spencer Eriri: I treat you like a geek, and you're trying to do all this to me... Aoyama Nanami: Impure relationships with the opposite sex, no! Shiina Mashiro: Hachiman, you're my first... Hikigaya Hachiman: It's all the system's fault!!!

(The combat power of all worlds has been balanced. Apologies for the ooc character design. The last Xu Fu kiss is adorable.)

Su Yin traveled through the Type-Moon world and thought he would become an ordinary person and live his life in fear, but unexpectedly he was bound to a knowledge system.

At the beginning, he gained the ability of [Knowledge Deconstruction] and was pulled into the chat group of all worlds, and from then on began his journey of continuous adventure across the world.

"Knowledge is the cornerstone of modern magic. With enough knowledge, any magic trick, even sorcery, can be deconstructed!"
