Serah Quotes in Yu-Gi-Oh!: The Dark Side of Dimensions (2016)

Yugi Moto: [Yugi is looking through his Monster cards and is looking at the Dark Magician card] Hm. No way could I build a deck without this card, you've gotten me out of more dueling jams then I can count.

Serah: That golden box. It has a kind of glow.

Yugi Moto: Sorry, I didn't hear you come in. But you're right. This box is very special. You see, it's where I keep my Duel Cards. Not every one of them of course, Just the ones that are extra precious to me.

Serah: Of course. But I think you mean cards that are extra precious to you and extra precious to the Pharaoh.
