Looking for this old anime
As the title states, I'm looking for an anime that was most likely made around the early 90's.
I do not remember the name of the show or the name of the characters, the only thing I can recall is that the main character was a high school girl who's family had a shrine. Now on the temple grounds was a statue of a guardian or deity that could be summoned to protect against evil. She somehow manages to revive him, but is merely a kid in his base form. He is able to transform--his red hair gets longer, gets fangs and he develops thorns(?) on his elbows.
That is all I am able to remember, if anyone out there has seen something similar to what I am describing let me know! It has been sort of impossible to find since I can't remember the name of the anime.
