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 Tokyo.

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

I thought I could only be a grocery store owner in the future.

But unexpectedly found a space-time gate in the warehouse.

[Confirm the first entry into the space-time gate - obtain ownership of the space-time gate]

Lin En found that he seemed to take off!

After traveling to the anime world dominated by the "science world", he obtained the golden finger of [career and love].

As long as the important heroines fall in love with him sincerely, he can get attribute points and skill points.

And if he can become the Prime Minister of Japan, he can also get the final reward.

As the fiancé of Shinomiya Kaguya, the lover of Vermouth, the relative of Yukinoshita Haruno and Yukino sisters, etc., Fujiwara Toru has established his goal and the peak of his life is just around the corner!

But when "Kawamata Kayako" and "Kawakami Tomie" also appeared in front of him, Fujiwara Toru found that this world was not right.

Can I get skill points by letting a ghost fall in love with me?

Urgent question: What should I pay attention to if I want to become the Prime Minister of Japan?

Answer: You must wear the best bulletproof vest, always wear a helmet on your head, the kind that can protect your neck, and have bulletproof glass on all sides when giving a speech!

Li Ze traveled through the anime world for seven years, and only when he became financially independent did he get the diary.

"As long as the content of the diary can make people believe it, can you keep getting rewards?"

"Can you travel through other worlds?"

[I didn't expect that the heavens would be so kind to me and give me a chance to be reborn. ]

So, the heroines were in a mess.

Chihaya Aine: "Why is Anon-chan's breasts flat? Jpg, which black fan photoshopped this picture? Speak!"

Kato Megumi: "You will definitely listen to my advice this time? But I really can't read minds."

Kirisu Mando: "A traitor to the master! Fulilian, Nangong Nayue... How many teachers do you have?"

Hestia: "He has a hundred wives, how jealous should I be?"

Tendo Kimura: "Li Ze helped me get revenge, and I pledged my love to him. It's reasonable

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!

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.)
