But Aikatsu isn't Pretty Cure, a magical girl fighting series about personal growth and friendship, and it's also not AKB0048. They might have little simularities, but several series are about friendships and growing as a person as well. Why not throw in some mystical treasure the idols need to seek, or little monster companions to keep them company?

Yume's power is strictly for Idoling purposes, not to make some evil group see the error of their ways. The wings have been a common gimmick for Idol attire, and the card to clothes gimmick is for merchandising.

I'm not saying you can't think up ideas like this, I'm just saying don't try to imagine Aikatsu as something it isn't, or else you'll be disappointed.
