He's a priest, but the only spell he can use is the simplest one: Holy Light.
As the gentle Holy Light shone steadily, Gael suddenly felt a chill on his head.
The little girl stared in shock at the wig in her hands.
With his head now completely bald, Gael rose to his feet, revealing a body as tall as a city wall and muscles carved with rugged strength.
"Please give me back my wig."
This is the story of a priest who wields Holy Light with his muscles.
Sometimes he may have to preach through personal example, too. Nuns, female knights, princesses, succubi, dragon girls, and elemental queens are all excellent targets to be touched by the Holy Light.
