The price for saving the world is the right to rule it. After saving a faraway land, Lyn Rivers was cast back to Earth. Wanting the admiration, prestige, and glory of saving that realm, she forced her way back. But she was forgotten, and someone else claimed credit for her deeds.

Reborn into the world of Yugioh, it's natural if my goal is to become the best duelist!

Gu Bai always believed that the stupidest thing he had ever done was listening to his bestie’s words of becoming a stallion genre novel writer, the most frustrating thing was that he changed the moral, smart, and healthy youngster, that he had decided on, into a big boss…but in the end, he discovered that the consequences of changing the original plot were more serious than he expected. Things like encountering the outrageous character he wrote with his own hand…

Oh·my·god! He freaking eats people! Right now, he can only turn devouring people into “devouring” people… maybe.

In short, this is a story about a dumb author who was the first to start a trend of human cannibalism in stallion genre novels, who in the end, was unable to escape from the whirlpool of destiny (not really).
