What should I do if I travel through time and space and become a fat otaku?

Masao Tanaka was extremely desperate. He had traveled through time. It would have been fine if his name and family were strangers, and it would have been fine if he hadn't been given a handsome face.

But why did he become a typical fat otaku like someone from an anime?

Fortunately, there is a system, but why is this system called the [Degenerate System]?

······

Yukinoshita Yukino: "It's really uncomfortable to be with Tanaka Jun."

Ying Lili: "You are a guy whose head is full of pornographic garbage. Come up with a new plot for me!"

Kasumigaoka Utaha: "I never thought that the person who wrote such a sweet novel would be you, Fat Otaku."

Yotsuya Miko: "Tanaka, help me, just destroy the evil spirits and let me..."

Fujiwara Chika: "Tanaka is really cute."

Goto Ichiri: "Tanaka, best friend."

Traveling through the world of Harry Potter, Lucien awakened the loan magic system. With a flick of his hand, he could advance his rewards!

Of course, debts still have to be repaid.

So, the students at Hogwarts got to know a new student who was not only better than you, but also more competitive than you.

[Congratulations to the host for obtaining "Loki's Faceless", please repay the loan: Perfectly master the art of transformation]

Dumbledore: "With talent and hard work, could it be that Lucien is the future of the wizarding world? But the prophecy..."

[Congratulations to the host for obtaining the "Dark Magic Encyclopedia". Please repay the loan: Voldemort's head]

Voldemort: "What do you mean you owe a debt and need to borrow my head?"

[Congratulations to the host for obtaining the "Resurrection Potion Formula". Please repay the loan: create fifty new potions.]

Snape: "Lucian has developed the formula for the resurrection potion? Lily... tell Dumbledore I'm resigning as Potions Professor? Go find Lucian!"

…

Lucien put his hands behind his back and said, "I didn't expect to be this good. I just took out too many loans."

The small white balls flew towards me like sharp arrows.

On the strike zone, the boy raised his bat high, facing the flying baseball, and whizzed out.

This is the story of a baseball boy chasing his dream of Koshien!

This is also the story of a relief pitcher who welcomes a new student in high school!

After traveling to the world of anime, I was expecting to live a romantic life with my fiancée, but unexpectedly, all sorts of strange creatures appeared. Dragon maids, magicians, and ghosts began to appear from time to time. "Come if you want, just don't interfere with my life."

By accident, Amamiya became a participant in a bizarre real-life escape game.

He soon discovered that he could see prompts hovering over both the monsters and his fellow players.

And so… things started to feel a bit off.

In the Ghost Academy, during a game of "statue," a ghostly girl on the playground looked at him with tear-filled eyes: "Don't come any closer!"

In the Horror Canteen: "Dear student, you’ve wasted food. I demand hush money."

In the Devil's Examination Room: "Is it wrong to bribe the evil ghost teacher with cash?"

Amamiya could also motivate his teammates.

[Player: Kaguya Shinomiya]

[Status: Crouching and trembling]

[Prompt: Please use the following methods to boost your teammate’s morale.]

Amamiya sighed. "Shinomiya-san, can you please show a little more spirit? Did you not eat?"

"…"

An ordinary boy traveled through time and became Qianyu Yeyou because he was very curious about the scientific magic in the anime, and the gorgeous magic began to truly bloom before his eyes.

Eh? You mean the ritual is disintegrated?

I think I know a little bit.

What? Frost and Mist Kingdom? I think I know a little bit about it...

I really want to

Transmigrating again, he came to the familiar world of Kuroko no Basket.

Having the idea that it’s better to become a team owner and watch others play basketball instead of working hard, Tendou Kageyoshi directly rejected his broken system.

But, nothing in life is absolute. As long as there are enough benefits it’s not impossible to negotiate.

Thus, Tendou Kageyoshi coupled with his system, embarked on the road to becoming the most popular character.

Tendou Kageyoshi: “First, set a small goal for myself—turn Kuroko no Basket into Tendou no Basket!”

Yu Shao, a national Go master, transmigrated to a parallel world and became a high school freshman. Given a second chance at life, he only wanted to enjoy a carefree and flamboyant youth, ensuring it wouldn’t slip through his fingers again.

But… why am I picking up Go pieces again?!

Although playing in a Go world untouched by harsh AI training makes it all too easy to dominate an era—it’s undeniably satisfying on some level.

[…]

A group of professional Go players: “Wait, you can play Go like this?”

Yu Shao nodded: “Yes, this is how Go is played!”

At the new game launch conference.

A reporter: "Hello, Mr. Nangong, congratulations on your work Pokémon surpassing Homunculus to become the world's number one IP the day before yesterday. Can I ask some questions?"

Nangong Yu: "Thank you, sure."

A reporter with an excited face: "I heard that you have a very close relationship with your secretary, the company's senior executives, the travel blogger with a large number of fans, and the eldest daughter of Yuedu Group. Is it true?"

Nangong Yu: "... Hey, hey, hey, where are the security guards? Get this troublemaker out!!"

...

ps: Harem-oriented, more daily life, no poison, no knives, of course, using the game to torture players is another matter~

Wade: I only studied at Hogwarts for seven years, which means 266 weeks excluding holidays! Even if I can finish a book in a week, 266 weeks is only 266 books! How many magic books are there in the Hogwarts library? Thousands of them! Time is running out, how can I not seize the time to study? ! I will never allow anyone to destroy my learning environment - not even the Dark Lord! No, no, no, I don't just love knowledge. I'm just greedy.
