What if?! Zarc and Ray in Yu-Gi-Oh Arc-V!

Episode 1: Familiar Strangers with Cards?!
We begin with a narration towards the origin of the Original Dimension.
Narrator: There was once a place where everyone participates in what is known as Duel Monsters. This place was the Original Dimension. During this time, a man named Leo Akaba invented Solid Vision which causes light to be filled with mass. With this comes what will be known as Action Duels. This allows for humans to interact with their monsters as though they are real. While it is indeed a revolutionary new way of dueling, it is not long before something tragic happened. A destructive dragon appeared and causes much destruction and chaos. To defeat that dragon, one must duel it and win. However, it was extremely difficult and it seemed that no one was able to beat it in a duel. Until a woman decided to sacrifice her life at last and put that Dragon to rest. No one has ever remembered that terrible event since. No one that is, except for Leo Akaba. After the woman's sacrifice has passed, the dimensions split into four and from there is where our story begins.
