Help! I've been searching for a story!
Yep, you've all heard that before, but seriously. I have been.
It's a Yu-Gi-Oh! and Harry Potter crossover, Yami and Yugi are neighbors with the Durselys, they get to know Harry. Then the Dursleys find out that Yami and Yugi are like Harry, don't want anything to do with him. Yami and Yugi end up at Hogwarts as the new D. A. D. A. teacher, but Yami is feeling bad because Voldemort is using the Shadow Relams to try to win the war.
That's all that I can remember.
Do you know what I'm talking about?
