[precure] Precure for the first 5 seasons: Offworlders can't be Precure because they're Earth's heroes. They have to be called something else. Precure today: All but one of the Precure on this team are either offworlders or descended from offworlders, and it's a reverse isekai now
I know the rule has been gone forever. Babies born when Cure Passion showed up are now the average age to become Precure themselves if they were real. It's still funny.
Luminous, the Kiryuu twins, and Rose were explicitly not Precure, even in the cases when they had the exact same powers and power source, until All Stars started calling them Precure.
Even then, Laura served the exact same function as Luminous in the first half of Tropical-Rouge and then explicitly became a Precure later on because she wasn't one before.
