Hmm, I got only one right now...
Shulk and Fiora (Xenoblade Chronicles)
Shulk and Fiora outside the Apocrypha Generator
"I'll fight on, and help him in any way I can."
- Fiora, to Melia
Shulk is a real man. Although his feelings for Fiora are not totally there at the beginning, he doesn't hesitate to travel halfway around the world to avenge her when she appears to die fighting Metal Face during the Mechon invasion of Colony 9. His patience pays off when he not only gets a good shot at Metal Face, but sees Fiora has survived, albeit with a mechanical body, totally possessed by another power, and fighting for the enemy. With advice from Fiora's big brother Dunban that she and Shulk belong together, Shulk's persistence would eventually see him reunited with Fiora, waking her from unconsciousness with a kiss at the Fallen Arm, Fiora having returned to her original self after becoming separated from Face Nemesis. His love for Fiora never wavers from then on out, even if she's in an ill-suited Mechon body that won't give her much time to live, and he has to fend off feelings from the High Entia princess Melia.
What a guy.
Fiora, too, fought tooth and nail to be united with her love Shulk, being forced to fight for her freedom against the Mechonis Goddess Meyneth and the Mechon Leader, Egil.
Neither Shulk nor Fiora would hesitate to defend the other with their life, and while they harbored...contrasting powers, they were able to toss them aside for each other.
At the end of the game...
