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."

Good news: I traveled to the daily world of anime girls.

Bad news: The style of the daily world suddenly changed, and it became a doomsday place where cursed spirits are rampant and demons and monsters are everywhere.

Good news: It's stable. I got the flo card drawing system. At the beginning, I inherited the old sword spirit base, killed all the demons and ghosts, and turned them into nutrients for my own growth.

Is there any bad news?

No, there will be no bad news in the future!

Ye Ran, who has countless heroic spirit bases, opened the infinite sword system, used Wang Cai to knock down countless monsters, and made the two-dimensional girls fall in love with him and start a happy life.

Kasumigaoka Utaha: Do you want to touch it? I'm wearing black silk today~

Kitagawa Umi: Dear, my cosplay is only for you to see.

Mizaki Mei: Another yin and yang eyes, how many good sisters do you have?

Kirisu Mando: You don't even let the teacher go?

Kanono Beno: I'm enough for your girlfriend. ...

As a human and devil hybrid as well as the House of Phenex’s fourth son, Tenraku faced pressure as great as a mountain.

He couldn’t study magic, nor awaken the bloodline of the phoenix. As such he became the Underworld’s famous waste.

But none of this mattered. He had his 【Sacred Gear Plunder】!

【Gauntlet of the Red Dragon Emperor – Boosted Gear】, 【Light Wings of the White Dragon Sovereign – Divine Dividing】, 【Holy Grail of the Secluded World – Sephiroth Graal】

So what if you’re an angel? So what if you’re a devil! Even if you’re a dragon god, so what!? Anything I want, I plunder! Plunder! Plunder!

After traveling to the world of anime, Hikage Miyauchi obtained a magical diary. As long as he wrote in it every day, he would get rewards.

But he had read diary online before traveling, and he knew that what he wrote would most likely be seen by the heroines of this world.

As a salted fish with no ambition, Hikage Miyauchi immediately decided to be a pure fun person in this world.

"What era is it? Who still writes traditional diaries?"

"No one is really willing to write their true feelings in a diary and then be watched by countless heroines, right?"

"My mother told me that this world is very dangerous. Boys must protect their privacy when they go out, so don't think about coming to me. After all, I am a man you will never get."

As Hikage Miyauchi continued to write in his diary, an "Avengers Alliance" composed of heroines who could see Hikage Miyauchi's diary was quietly born.

They gathered together for only one purpose, that is, to find the owner of this diary and ravage him inhumanely!
