History TearJerker / YuGiOhTheDarkSideOfDimensions

** He nearly breaks down when [[spoiler:Yugi completes the Puzzle and shows him it won't bring Atem back. He looks on the verge of tears]].

* Ryo Bakura's entire situation. Aigami forces him to have a flashback to how he got the Millennium Ring. [[spoiler:He got possessed by the Ring when he was four years old and had it fuse into his chest, leading to Dark Bakura killing Shadi and Ryo's father, and Aigami wants to kill him for the incident]]. Ryo mentions not wanting to talk about the Ring at ''all'' and suffers headaches when pressed, becomes trapped in another dimension for the last third of the movie, and has [[spoiler:the Ring itself drive Aigami and Mani to kill him]].

* The very last scene of the movie, where [[spoiler:against Mokuba's wishes, Seto breaches through to the afterlife and prepares to duel Atem. He has Aigami's Quantum Cube, but the movie leaves it up in the air as to whether going to the afterlife made him dead as well, and whether or not he'll win against Atem when he finally duels him. Complicating matters further is that he leaves [=KaibaCorp=] in Mokuba's hands, suggesting he may not return right away, if at all]].
** The Japanese version ends with [[https://www.youtube.com/watch?v=uaU3WDlMTss a remix]] of [[https://www.youtube.com/watch?v=oK93ufMCQ1Q Priest Seto's theme]] from the anime as [[spoiler:Kaiba arrives in the afterlife and walks to the palace]], and unlike the high-energy, bold original piece the DSOD version is slow, soft and has a sense of finality.
* The ending theme in the Japanese version, [[https://www.youtube.com/watch?v=PINYTwXV-Jg To Believe in Something]], seems to be about Kaiba's relationship with Atem. The fact that it comes after [[spoiler:Kaiba enters the afterlife to duel him]] makes it sadder.

** The shot in question is from when Yugi, Joey, and Tea are walking home from school. Taking out his deck Yugi admits that despite having moved on he still misses Atem. It's implied that Yugi rarely duels anymore because it just isn't the same without him.

** Particularly bad since the movie seems to follow the cannon of the manga more than the anime. In the manga Kaiba wasn’t there for the Ceremonial Duel. Unlike Yugi and the others Kaiba never got to say goodbye.

** When Joey is trapped in the alternate dimension, about to disappear forever, he doesn't think of his little sister, Serenity to give him strength. Even sadder is that she doesn't appear in this movie at all.
