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]?

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."

Shihouin Yanma's Zanpakutō awakened the ability to travel through worlds, forging a contract with the dead, granting him a portion of their abilities. His first stop was the world of Naruto. On the night of the Uchiha Clan's genocide, the souls of the fallen Uchiha clan faced the Grim Reaper, who presented them with a choice. "Submit to me, and I will grant you a second life, or perish. Your choice is yours." The Uchiha clan made their decision without hesitation. "We, the entire Uchiha clan, swear allegiance to you, sir." And this was only the beginning. Pirates, Jujutsu Kaisen, Demon Slayer, Nura: Demon Slayer... countless worlds await Yanma's arrival, and countless heroes await his capture after death. When he regains consciousness...

Upon traversing the Marvel universe, Chu Hang awakened the [Super Copier] cheat ability—the ability to permanently copy others, but with a cooldown period of up to seven days.

At the start of World War II, he decisively targeted Wolverine, who hadn't yet been infused with adamantium: "I choose you, Healing Factor!"

With this ability, he fought his way from Normandy to Berlin, becoming the legendary "undying ghost" on the front lines.

But he was lucky: seventy years later, a glacial current swept him out, and he happened to run into the scene of Captain Marvel's awakening!

"Friendly reminder: Your undigested [Cosmic Cube Energy] can be fused with new abilities."

While Iron Man was still hammering away at sheet metal in the cave, he had already used cosmic energy to create the Arc Reactor with his bare hands.

Just as Thanos finally collected all the Infinity Stones and snapped his fingers, Chu Hang had just returned from a vacation in the DC Universe.

"Sorry everyone, I just went next door and touched Superman's Kryptonian constitution."

"I'm shinier than kryptonite under the sun now."

"Today I'll show you why flowers are so red."
