Her Blood
The thing that frightened Gourry the most was the sight of her blood.
And every time she stepped up bravely into battle, the source of her power augmented into her tiny palm. He saw the look in her eyes, and it scared him every time.
It was win or die.
In the climax of battle, he would listen as she cast her spell. By her side, he was ready to give his life for hers. He couldn't be selfish just because he wanted to be with her.
He had to protect her indefinitely and prevent from ever seeing her blood.
