Yu-Gi-Oh! 5D's/Heartwarming

"Luna:I don't care if you're not a Signer, you're my brother, and that makes you my hero."
 * Episode 43.

"Leo: I'm not a Signer, but Luna, who bears the mark of a Signer, is my pride!"
 * The warm fuzzies are reciprocated later, in episode 78:

"Yusei: "Everyone, I've come back.""
 * Also doubles as a CMoA for Leo, who takes Luciano's plans to steal Ancient Fairy Dragon, which he'd already snagged, and completely derails them in a single move.
 * The aftermath of the  counts too.
 * The fallout from Leo becoming a Signer and getting Life Stream Dragon. Luna recovers and Leo says "What a surprise, huh?" Luna, being Luna, says something to the effect of "I'm not surprised. You're my brother and I know you'll always protect me." The exchange left both of the twins in tears and probably would have brought a tear to Jack Atlas' eye. If Jack Atlas cried.
 * Leo, struggling to accept the possibility of Sherry's prediction that  breaks down in a fit of sobs, which then upsets Luna. Yusei kneels down in front of them and they both jump into his arms and shake so hard from their crying that they manage to make his body shudder with him.
 * Something about the scene where we first see Yusei and Crow together, meeting for the first time in presumably years, always makes me feel warm and fuzzy inside.
 * All the prisoners in the detention center giving Yusei their cards for his duel with the warden.
 * Yusei's encounter with the spirit of his father in some sort of Momentum limbo after his duel with Rudger.
 * If the scene where  didn't at least have you crack a smile, you DO NOT HAVE A SOUL. Double goes for the scene earlier on,
 * This may only apply to those who ship Jack and Carly, but episode 59 is practically an episode of heartwarming.
 * Episode 151.


 * Almost everything in episode 154.
 * The last time Yusei's father saves him. That made this Troper really happy.
 * Akiza and Yusei's final moment in Episode 154. (This doubled as a Tear Jerker moment for this Troper, because at that moment, it hit her that Yu-Gi-Oh! 5D's was over.)
