Yu-Gi-Oh! Zexal/Heartwarming


 * Shark "returning the favor" to Yuma by refusing to hand over the Ou's Key to Kaito and dueling him to keep it away from him.
 * Kaito, although an Antagonist, shows he really does care about his younger brother when they interact.
 * In episode 50 Droite finds out Kaito's photon change is killing him and she asks him to drop out of the tournament for his own safety. The genuine concern she shows for him is quite touching when you remember Droite's usual disposition.
 * Droite smiling when Gauche manages to defeat Fuya in episode 45.
