True Duelist: Serena x male reader

y/n is a slider red from academia, who use to be ok-ish friends with Serena. When she went missing, he got very worried as he had no idea where she was but he had heard some rumors that she was now working with the Lancers in the standard dimension. He decided to go find her, not to bring her back but to just be with her again.

Some changes I made to the story are
Yuya, Yugo, and Yuto are all Lancers together.
Rin hasn't gotten kidnapped yet.
This happens after Yuzus went missing but before the friendship cup.
Yuzu is stuck with Jack (I know, yikes) in the synchro dimension instead of Yugo, since he's in standard.

The deck y/n uses is an archetype I made myself called Timeless HEROs which are fusions between Ancient HEROs and Future HEROs which I also made up myself.

I don't own any of the characters or cards (except the Timeless HEROs) all rights go to the proper owners
