What happens when a fanfic author with a habit of lying and scheming suddenly finds himself as a self insert during Duelist Kingdom? What happens when you have Yugi, Joey, Kaiba, and the rest encounter someone who knows all about every major player in their saga... and sees no problem with abusing said knowledge? Chaos, dear reader. Sweet, sweet chaos

A man betrayed by a comrade dies a wretched death as a third rate swordsman. His existence, his life, his emotions are all a nuisance in the eyes of society. But wait… What’s this green skin? Reincarnated as a goblin? Wait, I went back in time as well?

A disappearing gold mine. An old family secret. An army officer carrying a grudge spanning two generations.

As a small time reporter at the local newspaper, Shen Yu already had enough on her plate. Biased managers, check. Long, brutal work hours, check. The department beauty snatching her big story opportunity, check. But now another problem has reared its head and it comes packaged in a young and attractive military officer. He is on the hunt for some legendary space gold and he will get her to help him, whether she likes it or not.

Secrets are abound and Shen Yu soon finds that not everything is not as simple as it seems. Even her own past becomes questionable the more time she spends on the quest. Events from decades ago are rising up to haunt her and she needs to find out the truth before it’s too late. If only she had a better partner.

Zhou Yu, a reclusive otaku, who did not like to go out of his house, was one day forced out of his house by a series of unexpected events.
