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."

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..."

The strongest Red Dragon Emperor, one of the three royal families of Kyoto Onmyoji, the essence of the flower blossom courtyard family - the daily day of the Buddha conversion of the flower blossom courtyard.

Get up in the morning, wake up the girlfriends next to you first, and if it's the wife nine-tailed fox Yasaka and the cat and big sister Hei Ge together, let them cooperate with each other to avoid tail knots, and then start morning exercises.

Towards the end of the morning workout, the maid group led by Grefia will come in to help wash and change clothes, but occasionally the maid group will come in early to join in.

After washing up and having breakfast, Dr. Yasaka and Chisato Hasegawa sometimes want to feed it himself, but the normal staple food still has to be eaten, otherwise it doesn't matter if it's full.

After breakfast, we leave for school, but if Janovia and Yuki Nonaka don't show up until before departure, it's best to be with Lias and Mio Naruse, otherwise you'll be able to miss school all day.

As for the afternoon, if there is an arrangement, it is best to do lunch by yourself, even if it is a lunch sent by Senior Sister Zhu Nai, it is best to let the maid group check it, and the same goes for dinner.

Washing up before going to bed is casual, but if you want to go to bed early or do it yourself, don't count on the maid group at this time, their professional ethics should not be able to withstand after a day's test.

There is no sky-drop system and no built-in plug-ins.

What would it be like to awaken a different superpower every week?

Kiyoshi Minazuki is reborn into a crossover anime world. Hoshino Ai is not only his childhood friend, but also the aloof and unattainable Yukinoshita at his school. Other characters include the genius writer Kasumigaoka Utaha, the rare blonde beauty Eriri, and the transfer student from abroad, Ellie, among others.

News about Mai Sakurajima, who debuted as a child star and is currently semi-retired, can still be found online.

At the same time, he gained a system that allowed him to awaken his superpowers once a week.

Dream manipulation, teleportation, telekinesis, and more...

All sorts of strange and imaginative abilities appeared one after another.

Furthermore, the art style can change instantly depending on how the user interacts with it; there are indescribable controls, such as pausing and perspective...

Just as Kiyoshi Minazuki was considering how to remake a "Stop Series" film and was preparing to finalize the casting of the important female characters,

Looking at the girls around him, he belatedly realized something.

That is...maybe...he didn't need to pause time or make a choice at all?

Because the girls are too enthusiastic.

Traveling through the world of Soman, Nakano Yuu starts with the [Oldest God Killer System], completes the system tasks, gets the number of draws, draws the power of gods and various artifacts!

Just when Nakano Yuu fantasized about hunting down the God of Disobedience and becoming the strongest demon king, he didn't expect that this was actually a weird world where monsters and weirdness coexist? ! !

Fortunately, he got the [Ten Powers of the God of War] and the holy sword Juvayus at the beginning.

Facing five sisters with different personalities, Nakano Yuu originally planned to be the only demon king in the world and enjoy life, but he didn't expect...

The second sister Nino went home from school and was haunted by a cursed female ghost named "Shirai".

Just after rescuing the second sister, classmate Gui Yanye suddenly got involved in a weird story called "Sarumu"!

After finally dealing with the Sarumu, a god of disobedience was suddenly summoned above the school.

After finally dealing with the God of Disobedience, I thought life was like this, but a girl who claimed to be able to see "spirits" suddenly asked him for help.

Looking at the different girls around him, Nakano Yuu was silent.

Is there something wrong here?

Traversing a strange world, Akita Makoto initially thought he was the only unlucky soul. It wasn't until various anime characters arrived that he realized he was the luckiest, possessing status, power, and an organization. In comparison, the protagonists who started as refugees were truly miserable. Kasumigaoka Utaha: "So, what's the point of having six children? Do you think we're pigs?" Hayasaka Ai: "I'm just a maid. Let others handle this difficult task." The other women looked at Eriri, who was still unaware of her situation. P.S.: This introduction is too sparse, please refer to the main text.

An accident sends Bai Ziyu traveling to the early 20th century in Neon. After nineteen years of silence, he suddenly awakens his past life memories! Then, he realizes something's amiss. He's a third-year student at Maple Academy, and his deskmate is named Marina Kamisaki. Soon, her mother is planning to marry a teacher named Kozo Akizuki. And that's not the end of it: another classmate, a yellow-haired man named Kazuhiko Amemiya, is rumored to have a new stepmother for him. Oh my god, this is a shabby anime-inspired world. Just then, the time-traveling system—a standard feature for time travelers—makes its grand entrance. Saving the goddesses with a beauty rating of over 90 from the original show grants rescue points to empower oneself. With the system's help, Bai Ziyu races on to save the goddesses and annihilate the Minotaur. (Note: This is the protagonist's past life awakening, not a soul-transmigration.)

Qiubai has traveled to a world where inner and outer worlds merge. Growing up, he's surrounded by characters he's "familiar" with. There's Akizuki Airi, Akizuki Marina, Shiina Chizuru, Mashiro Chisato, Hoshizuki Kaede, Hoshizuki Suzu, Nanao Akane... and his two younger sisters, Mikan Yuuki and Kasugano Sora, who live with him. Mikan is young, but capable, mature, and energetic, taking care of the housework daily, making her a worry-free existence. Sora is slightly older, but aloof and tsundere, with a slightly frail constitution. She stays at home every day, a worrying prospect. When Qiubai turns 18, the system officially activates! Kuze Akibai: What? Just coming of age, I have to become a male succubus in the inner and outer worlds? And I even have the ability to stop time!
