The moment the little tyrant of the nobles, Roel Ascart, saw his stepsister, he recalled his memories. He realized that he was in the world of a gal game he played in his previous life. To make things worse, he was the greatest villain in the common route of the game!

“I’ll be killed by the main character and the four capture targets ten years from now. Is there still any hope for me?”

Just thinking about the fearsome glints of those sharp swords those beautiful capture targets held in their hands, Roel couldn’t help but tremble in fear.

Till a voice finally sounded in his head.

【Welcome to the House Resurgence System】

Chen Yan travels between worlds, ending up becoming an honorable prince in a medieval fantasy world. Yet this world was not quite as simple as he thought. Witches with magical powers abound, and fearsome wars between churches and kingdoms rage throughout the land.

Roland, a prince regarded as hopeless by his own father and assigned to the worst fief, spends his time developing a poor and backward town into a strong and modern city, while fighting against his siblings for the throne and absolute control over the kingdom. Join Roland as he befriends and allies with witches and, through fighting and even farming, pushes back invaders coming from the realm of evil.

Without a simulator, without a system, I'm the cheat. I've learned one thing from my short life: the more content you are, the less you gain! (What are you trying to say?!) So, I'm going to be a pervert! ...But, maybe being less perverted is fine. Ishikawa Hayabusa, dressed in a white suit, glanced back at the four girls behind him, dressed in pure white wedding dresses, who were looking at him with either resignation or anticipation.

[No system + deserted island + age difference + survival + hegemony] A mysterious lightning struck the cruise ship, and Zhou Feng woke up on the beach. Next to him was Qin Xiaoxue, the aunt next door. Soon they discovered that the secrets of this island exceeded their imagination.

In the howling northern wilderness, Louis Calvin wrapped himself in a wolfskin cloak and stood alone on an ice cliff.

As the son of a duke, he was thrown into this permafrost wilderness by his family in the name of "opening up glory".

He thought he was doomed, but he didn't expect the daily intelligence system to be activated:

[Thirty-seven frozen hungry wolves are lurking in the southeast valley and will raid the territory tonight.]

[The corpse of an ancient god will float out of the ice lake at dawn, and the divinity of winter will remain in its heart.]

[The Plantagenet Church will regard you as a blasphemer, and the Holy Flame Knights have embarked on the road to the north]

[The undead frenzy will sweep across the continent, and only one in a million humans will survive.]

...

While the southern nobles were scheming for power, Louis's cavalry had already crushed the barbarian tribes.

The frost dragon roared over the Frost Iron Wall.

Winter has arrived, and this storm will eventually engulf the entire continent.

Police: "Alright then. In that case, experiencing our station's pork cutlet rice can be part of your youthful adventures too."

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."

Lin transmigrated to detective conan universe with the death note.

"Anyone whose name is written in the note will die."

"How can such an unscientific thing be possible?"

"If it's true, wouldn't we be able to rule the world?"

"You think so, don't you, Mr. Gin?"

"By the way, could you please sign an autograph for me?"

"Use your real name."
