Sabrina the Teenage Witch/Mage: The Ascension
Keeping her magic secret is important not because of mortal paranoia, but because of Paradox accumulation. Her spells go awry because she's burning off Paradox flaws. The linen closet is actually a Shallowing. The Victorian house is their Sanctum which is why the aunts can use their magic but she's in a school surrounded by mortals. What would be coincidental magic at home becomes vulgar without witnesses at school. The Other Realm is the Umbra. She can go to Mars, because Mars is actually a Spirit Realm.
