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."

"Uchiha's monsters have landed in Loulan!"

"The man-eating devil is slaughtering in the Wind Kingdom!"

"The arrogant false king is approaching the Fire Kingdom!"

"Uchiha Tenshu is fighting a decisive battle against the coalition of five nations!"

"The great sun of the ninja world is about to come!" ...

"Don't I just want to be the emperor? Do you have to demonize me like this!" Uchiha Tenshu said speechlessly.
