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."

······

Shiraishi traveled to the world of soongan, where there are characters such as Yukinoshita Yukino, Yotsuya Miko, Eriri, Shinomiya Kaguya, etc., and also awakened the career panel. He attended classes and studied hard, awakened the "student" career, and his grades improved by leaps and bounds. By participating in the school's home economics and cooking class, he can unlock the "chef" career. ... Each career can make Shiraishi grow stronger by gaining experience. He met the transfer student Yotsuya Miko and unlocked the extraordinary career "Forced Exorcist"! Encountered Bloody Mary at the beginning. As a forced exorcist in Lisha, facing Bloody Mary (female imp loli), he had to use special means to force exorcism... Later, he even joined the dimensional chat room and began to evolve extraordinary. Entering the world of Suqing, he started the career of "Grand Mage" and killed gods in the world of God Slayer, starting a new career "God Slayer"... Unknowingly, Shiraishi has become a multi-level existence, overwhelming the heavens and all worlds.

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]

[Confirmed to have obtained the title - Traveler from Another World]

[Confirmed to have received the Protection - Favor of the God of Time and Space]

[Confirmed to have acquired the inherent skill - Super-speed Growth]

[Confirmed to have acquired the unique skill - Time Traveler]

After walking out of the space-time gate.

Lin En found that he seemed to take off!

I transmigrated into the body of an ordinary student at a Japanese elite academy and became bound to the Involution System.

Before enrolling, a scan of all the passengers on the bus revealed that Kiyotaka Ayanokoji's fighting skills were S-rank!

Kikyo Kushida's social skills are grade A, Rokusuke Koenji's aristocratic manners are grade B...

I sat quietly in the corner, but in my mind I was practicing martial arts in the virtual space.

The moment Ayanokouji looked at me, the system notification appeared: [Martial Arts (S-rank) Successfully Acquired]

He will never know that with just that one glance, I had already been "killed" a hundred times in my mental world.

(Multiple female characters + The Quintessential Quintuplets + One Piece + Naruto + Genshin Impact + Honkai Impact 3rd + Demon Slayer...)

Good news: Nakano Yuri has received the golden touch of hard work paying off.

Bad news: This is just an ordinary world. I thought I was going to live a peaceful life as a dragon king, a literary master, or something similar.

But unexpectedly, he joined the multiverse chat group.

Thus, the worlds welcomed a great demon king who defied the heavens.

Give him a breathing technique, and he mastered it on the spot, innovated upon it, and won over Kanroji Mitsuri;

Give him a gentle punch, and he will master it on the spot, thus conquering Kaguya Otsutsuki.

Give him a Devil Fruit, and he immediately understands its essence and masters countless fruit abilities;

At the end of the cycle of hard work and perseverance, Nakano Yuri transcends multiple realms and becomes the strongest being in the world of crossover anime.

When everyone asked him why he had become so strong so quickly, Nakano Yuri replied, "You reap what you sow. Just work as hard as I have!"

(Currently, the world's most popular anime and manga series include One Piece, Naruto, Demon Slayer, Date A Live, and Konosuba.)

Bai Ye, who was reincarnated into a world full of various supernatural powers such as cursed spirits, demons, and Onmyoji, was severely damaged in a crisis he was involved in, and at that time he awakened the memory of his past life, and at that time the cheat also arrived. At the beginning, he obtained the power of chaos among the three ancient powers of Marvel. After the initial fusion of this power, he found that he seemed to be invincible in this world. However, when he received the second reward, he suddenly fell silent, because the second reward turned out to be the legendary Pear God Physique (rule level), and gradually various accidents appeared in his life. Yukinoshita Yukino: Bastard, you did it on purpose! Shinomiya Kaguya: I seriously suspect that you deliberately knocked me down, you scumbag with a head full of lust. Kasumigaoka Utaha: As expected, you are a hentai, junior! Bai Ye felt that this chaotic life added a lot of fun to his invincible power, but when he heard the invitation of the chat group with a ding one day, Bai Ye felt that greater fun was coming.

Lin Ye travels through the second dimension, activating his superpowers. Upon opening his eyes, he's rejected by Hoshino Ai. Unexpectedly, this isn't just the everyday world; the 'other world' unfolds. Welcome to the 'Weird Game,' and the first game begins. "You'll spend a wonderful night at the 'Love Heart Love Hotel.'" [Time Stop] activated! "It's not difficult, just play around." Mind voices, hypnosis, possession, clairvoyance, and other superpowers all come to him.

[The Strongest Weird Investigator] [The No. 1 Male Lead in the Other World]. "This world is so dangerous. My back hurts, my legs are sore, and women slow me down with my sword." Hoshino Ai: "Let me confess. Ai-chan, I like you, Makima: Come back to class with me, play whatever you want." Asuna: Play games with me, a weird game for adults. Kaguya Shinomiya: "The Shinomiya chaebol, isn't this enough for a dowry?" "I said no, don't come over here anymore." "Lin Ye felt that solving strange problems in the game was more fun.

(Multiple female protagonists + Ayanokouji's gender change + romance + no entry if you don't like it) Hoshino Kanade is a time traveler who doesn't think she has many outstanding qualities. Although coming to Tokyo Metropolitan Ikusei High School was not her wish, it has come to this point, so let's eat first. (This is my first time writing fanfiction, please accept my first time)

Featuring characters from The Angel Next Door, Oregairu, Shikimori’s Not Just a Cutie, The Quintessential Quintuplets, Saekano, Mai Sakurajima, and more… (More may be added based on reader suggestions!)

At first, the protagonist is just an average guy — but he’ll grow quickly!

All he wants is to enjoy a laid-back life in the 2D world.

So why is he suddenly surrounded by real-life romance, social drama… and even love triangles?!

Expect a chill atmosphere, slice-of-life comedy, romance, and the occasional battle of love.

Light system elements, little plagiarism, and Shikimori appears a bit later in the story.
