Yu-Gi-Oh!, Season 4: Waking with Dragons

Joey:
Congratulations. You win.

(Collapses from exhaustion)

Mai:
Joey, no!! You're wrong. I never attacked so you didn't lose the duel.

Joey:
But, I'm too exhausted... to finish.

Mai:
I won't let the Orichalcos take you away, Joey.

Joey:
It's too late for that. I already lost the duel, so there's no turnin' back. I'm just glad that if one of us had to lose our soul, it didn't have to be you, Mai.

Mai:
Don't say that.

Joey:
Hey, Mai, that was one of the greatest duels I ever fought. Thank you.

(His spirit is taken by the Seal, leaving Mai horrified)

Mai:
Joey!! NO!!

(The fragment of the Orchicalcos on her choker shatters)

Dartz:
She's been set free! [spots at Joey Wheeler in stone] Ah! But what's this? It seems miss Valentine has served her purpose.
