My name is Youga, my surname is Youga and my given name is Wo. I'm a time traveler who accidentally traveled to the world of Yu-Gi-Oh! DM and got a 'Duel Links System', and it's the international version. I was very happy at first...

"But why are there only RD mode cards?! OMG!!!" (Heartbroken)

......

Coming to this world where playing cards determines everything, as a veteran card player (old-fashioned), the protagonist naturally chooses to participate.

In numerous duels, Yuga continuously strengthens his deck with the help of the system. Even if he can only use RD cards, he is determined to become the Duel King!

PS: The RD card pool is too shallow, so I will only write about GX at most.
