Upon waking, Nobita finds himself sixty years behind in technology. In the town of Tsukimidai, all memories of Doraemon vanish along with the regressed era. After a series of twists and turns, Nobita and his friends learn the truth: an unprecedented, massive, and trans-temporal war is unfolding, its target the future where humanity's technology is booming. The dominoes hidden in the past have already fallen, about to form a colossal wave that will engulf every era of humanity. The only clue is a snapshot taken across time. On September 19, 1492, at the center of the temporal vortex, the Time Police captured a photograph of the back of a blue nursing cat-shaped robot. This becomes the catalyst for Nobita and his friends being drawn into this trans-temporal heist. As they uncover more and more clues across different eras, a massive conspiracy gradually surfaces.

Congratulations on being chosen as the god of the new world! After becoming a god, Niko not only built a world of unity of multiple worlds, but also immediately took Ryomen Sukuna as his disciple!

Unexpectedly, in order to make the protagonist's life more interesting, the system started off in an unbelievable way.

At the age of 3, Zenji Naoki said: "Son-in-law, you're in charge of the future!"

At age 5, Xia Youjie said: She will be my wife!

Megumi Fushiguro: Did you ask me how I felt?

Kotoko Iwanaga: Absolutely not! She wants to rule the entire universe!

Shigeo Kageyama: Gojo-sensei, I don't want to go to school here!

Gojou: I'll teach you how to expand your domain!

Thus began the life of Koko, who, despite being invincible, had to become a student at the Tokyo Metropolitan Jujutsu Higher Specialized School.

In some desolate place, a group of systems surrounded a beautiful young girl...

Asuka (looking blankly): What is a human body? We are both system consciousness entities, so why are you creating a human body for me?

The systems sighed repeatedly: Although we are all consciousness entities and it is only a matter of time before we become systems, your consciousness entity has a defect.

Creating a human body for you is merely a way to transport you to a lower-dimensional world and fill in the emotional gaps you lack.

Asuka the girl: I don't understand?

All the systems: Whether you understand or not, go in!

......

By a twist of fate, Shimizu Asuka wakes up in the dimension where Nohara Shinnosuke lives.

Misae Nohara: Oh, Xiangxiang, how many minutes do you bake the beef pancakes you taught me to make yesterday?

Shinnosuke Nohara: Asuka-neechan, would you... be my bride?

Hiroshi Nohara: Koko, could you please brew some more fruit wine? Our company's chairman seems to really like it.

After confirming that he was indeed Hiroshi Nohara who had traveled back to a parallel universe, he made a solemn vow in his heart—in this life, he must break free from the trajectory of the past and live a completely different life!

Japan is currently enjoying its heyday, much like in the 1990s. The fervor of the bubble economy has not yet subsided, and the city is brimming with prosperity, as if it were a scene of blazing fire and blooming flowers.

Hiroshi Nohara has made up his mind to embark on a brand new journey—entering the political arena and carving out his own niche on the stage of power!

College student Niu Ma travels to the world of Crayon Shin-chan

Shin-chan: Little Qiuqiu, you have to call me brother!

Xiao Kui: Ahhhhh!

Nohara Aki: The life of a salted fish is so good

Xiaobai: Woof woof

Lin Zhe, a 21st-century college student, transmigrates into the body of a 6-year-old child. He wakes up in a room decorated with images of Action Kamen, confirming his presence in the world through the Nohara family's house number and the streetscape of Kasukabe. Shocked and bewildered by his childlike reflection in the mirror, he simultaneously receives the original owner's memories, learning that he is a transfer student at Futaba Kindergarten, thus beginning his new life in Kasukabe. ...

Having transmigrated into the body of Hiroshi Nohara's younger brother, a graduate of the University of Tokyo, I was only twenty-five years old when I received an international academic award.

He thought he could sweep through the scientific community with his talent, but he was mercilessly defeated by his five-year-old nephew.

"Uncle doesn't even know Action Kamen, how silly of him—" Shin-chan shook his head and sighed, while the beautiful teachers covered their mouths and chuckled.

Late at night, Nini's mother quietly knocked on the door: "Um... actually, I'm a big fan of your research..."

Suddenly, a shocked gasp came from outside the crack in the door: "Uncle, what's going on?!"
