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]?

Fujiwara Chika: "Tanaka is really cute."

Goto Ichiri: "Tanaka, best friend."

"Hey, man, did you know? The world's number one swordsman has been replaced?"

"What? There is such a thing. Who is the new world's number one swordsman?"

"It's a female swordsman named Miyamoto Musashi. Not only that, I have other explosive news. The title of "World's Strongest" has also been replaced. It is a queen named Scathach; and the navy hero Garp was also defeated by an old man named Li Shuwen; and..." "

"You?! Who are you?"

"I am the leader of [Blue Star]!" The protagonist said with a smile.

"What do you mean I'm a Bride!?"

"I never even thought about anything weird like a harem! I'm serious! So, you weird women, stay away from me!!!"

Years later, when the protagonists returned, they stared at their empty clans and vanished families, roaring: “Qin Xiao, you dog! Where are my clansmen? Where are my family? What have you done with them?!”

Hearing this, Qin Xiao smiled faintly: “They’re all working as servants in my mansion now!”
