God Wants to Purify Me, but My Parents Stew Against God

My father is a vampire, my mother is a nine-tailed fox, my brother is a half-demon, and I am just a weak human who can't even unscrew a bottle cap. Our family lived an ordinary happy life by ourselves, until the day of my coming-of-age ceremony, the goddess came to the world, declared me a disaster star in public, and casually set a date for my death. Since the gods are unfair, don't blame my family, it's "very spicy".
