Yu-Gi-Oh!

I, No. 47, Am the legendary silent assassin. In my previous life, I was given nothing during the Dark Shark's Great Luck. I tried my best but failed to scratch the enemy's armor. In this life, I traveled to a world called "Yu-Gi-Oh!" And I want to get back everything I once had. The first is this guy named Yu Dou. My agent asked me to find out his background. It's time to show his true strength. Found out, haha. Sure enough, it still has to be like this, "Let's duel, Yu Dou, I win, just pretend you have never seen me." I'm sorry, You Dou, this is all the system's fault. Why, Dark Shark, do you have such rich rewards? (The male protagonist is not a serious card player, and will often engage in off-site tricks, and the cheater will accidentally enter)
