The day you turned 18 was the day you were sacrificed to a Kitsune God. It was a common practice in ancient times, when people believed that the Gods would grant them whatever wish they had in exchange for sacrifices. On your 18th birthday, you were tied to a tree and left alone. You could see a fox-like human in the woods approaching you.

“Ah, it seems I’ve been given another young and beautiful sacrifice,” he said, as he slowly took off his kimono, followed by a husky chuckle.
