Yu-Gi-Oh!/Heartwarming

Original Series

Are we forgetting when after Yugi wins Joey's Red-Eyes Black Dragon back from the Rare Hunter and Joey tells him to keep it?
Joey's "death" (close enough) in Mai's arms.
Mai giving Joey her admittance card so he can enter the duel after Bandit Keith stole his.
Yugi giving Jounouchi the three million yen prize money for his sister's operation.
This troper thinks that Mako's sullen acceptance of his loss to Jounouchi (and by association, his father's disappearance), where he just barely holds back from crying and smiles, congratulating Jounouchi on his win.
The end of Yugi's duel with the possessed Joey at the pier. There have been plenty of CMoH's in the series history, but only one was so heartwarming that Little Kuriboh was unable to make fun of it.
- That entire episode was just one big CMOH for Yugi. The boy thrives on them.
- And Serenity too, particularly at the end of the duel when her she leaps into the water after her brother and swim down to save him (bearing in mind she's recently had major eye surgery and her bandages only came off about twenty seconds ago. She held back because she wanted the first thing she saw to be her brother, dueling).
- In the manga, Kaiba saves Jou. KAIBA. It's a CMOH to see Kaiba giving a good damn about anyone besides himself and his brother, let alone his rival/pet annoyance.
- Oddly enough, made even better in the Abridged Series. Serenity saves Joeys life and tells him she'll always love him, no matter what. This is in spite of the fact that he's been consistently mean and impatient with her, and did absolutely nothing to help her eyesight.
Kisara's death, not only for obvious reasons but because that whole arc gives a whole new perspective to Kaiba's connection to his Blue-Eyes White Dragon.
- Until of course you consider that present day Kaiba considers BEWD his personal BFG of Duel Monsters domination, first and foremost. Kaiba's outright denial of his emotional connection to the past is downright hearbreaking at times, for this reason most of all.
  - This shoots right back to heartwarming for this troper when you consider, in the anime at least, who the other two Blue-Eyes in Kaiba's deck are. Kaiba may consider his Blue-Eyes something like personal BFG s but it's fine because in doing so he reunited Kisara and Seto forever in his deck as BEWD s . As well as Seto's father, though it does raise some questions then about the relationship between Kaiba and Seto if Seto became a Blue-Eyes.
- Notably, Word of God has explictly stated that the relationship between Seto and Kisara was meant to define the bond between Kaiba and his Blue Eyes.
Manga only, during the first night of Duelist Kingdom there is a scene where Yuugi and Anzu are reminiscing about old times, and Yuugi offers to have Yami come out, convinced that he's who Anzu really wants to talk to. Anzu grabs Yuugi's hand and tells him he doesn't have to. "You're just fine the way you are." Awwww.
Then there's the episode in which Jounouchi brings himself out of a coma so he can watch Yugi duel. Especially since earlier, Honda had him by the neck and was shaking him, almost in tears, telling him he had to wake up to go watch the duel.
Episode 52, when Yami tells Yugi that he has no memories of who he used to be. Yugi starts getting a little freaked out about it all, until Yami tells him that he doesn't care who he was -he just wants to stay with Yugi.

Yugi: Me too. Forever. I will give you all of my memories.

- Just as heartwarming in the dub too, even though 4kids changed it around.

Yugi: But what if I...fail again? (near tears) How do I know I won't lose you?
Yami: I believe in you, Yugi.

Another big one for Yugi is the episode before when the Puzzle has been stolen, chained to a wall, and broken into pieces and now the whole building is on fire. Yugi refuses to abandon Yami and the Puzzle and stays in the burning building to complete the Puzzle and try to free it from the chains. Even when he passes out he still protectively clutches the Puzzle and refuses to let go.
Kaiba's smile at the end of his duel with Noa (Virtual Nightmare arc) as his brother rushes to him, now free from Noa's Mind Control.
- Also, when he's trying to break Mokuba's mind control, Kaiba's expression whenever he draws cards from his deck, hoping that it will be the Blue-Eyes is heart wrenching. It's probably the only time he trembles in fear and desperation. It would be downright tear jerker were he not such a jerk.
  - It's a downright tear-jerker either way, whether he's a jerk or not. No, BECAUSE he is one: it proves that Kaiba, the same guy who has in the past done anything to win and not given a damn what he does to achieve his win, seeming downright heartless, really does love his little brother.
Upon arrival in ancient Egypt Yami is deeply confused. He still has no memories of his former life, and wonders if the people around him are his friends or merely his servants. Immediately afterward Mahaad comes up because he was concerned about Yami's safety, and leds him away. Not a minute later, Yami is full-on glomped by Mana. As Yami watches the two argue, the look on his face says that his question's been very thoroughly answered.
In the original manga, Yami has to rescue Yugi's soul from a Chinese shadow game called Dragon Cards. The expression on his face when Yugi's soul returns is so tender makes this troper's heart melt, and it's made even better by the fact that it looks like he's trying to hug Yugi's soul. The scene can be viewed here.
"I love you, Jonouchi-kun." Forget Ho Yay, that made me cry. To This Troper, it confirmed the deep, caring bond between two best friends.
The ending. Face it, you were crying happy tears. Sad tears, too.
There's a blink-and-you-miss-it example early in the duellist arc in the manga. The characters are just getting used to the idea that the other Yugi is a separate person instead of just Yugi acting weird (or, Yugi is getting used to it, and his friends are looking awkward). Yugi mentions that his other self is feeling sad, and Jonouchi leans in to the Millennium Puzzle and shouts "Cheer up, Other Yugi!" Later on, Jonouchi gets some bad news about his sister and gets angsty. Yugi looks like he wants to comfort his friend, there's a scene from behind Yugi's head as he approaches... and then the Other Yugi leans in and shouts "Cheer up, Jonouchi!" It's not much, until you consider that three books ago, the Other Yugi was still setting people on fire for fun.
Hell, can we just say that any scene where Yugi and his Other Self/Pharaoh Atem interact is a Crowning Moment of Heartwarming? The devotion they have for each other is truly d'awww inducing.
During the Virtual Nightmare Arc, as Yugi's running to find Anzu, he can hear her calling his name for help, and thinks he's not really the one she's calling, that he knows very well that she wants his other self. But when he finds her and she regains consciousness in his arms, she throws her arms around him and cries that she knew he would come to save her. She was thinking of him all along!
In the duel against Dartz, Dartz reduces Yami's lifepoints to zero, but he saves himself with Relay Soul. He summons Dark Magician Girl, and cannot lose until she is destroyed. Yami says that their lives are now connected, and he will protect her. His speech sounds like a love confession.
After Yugi defeats Raphael's Dreadscythe, at first it seems like Raphael is still consumed by darkness, as he goes right back to dueling. But then, he gives up all of his Life Points to bring back the monsters he had sacrificed to give Dreadscythe power. He was willing to give up his own soul to the Oricalchos to save his monsters. Then, instead of having his soul taken, the ghosts of Raphael's family appear, along with Guardian Eatos, and let him know that they never left him, and never gave up on him.
In a flashback to Ancient Egypt, Mahaad gets bitten by a snake. Atem immediately rushes to him and tries to suck the venom out. Mahaad is shocked and asks him to stop, as it is improper for the Prince to be doing such a thing for a servant. Atem replies that he doesn't care about such things, he has been bitten by a snake and he's going to save him. Mahaad was amazed by his kindness and swore to always protect him, realizing he would make a most worthy pharaoh.
