The Bureau of Beautiful Soldiers is a catch-all universe for my magical girl characters.  In this universe, magical girl-ism is a bit like the Chicken Pox.  You get it as a kid, you have it for a while, it wears off, you're immunized.  But if you get it as an adult, it's a motherfucker.  

Mahou-ism usually occurs between 10 and 16 and lasts for 1-3 years.  If contracted as an adult, it is a permanent condition.  Some carriers contract mahou-ism as a child and carry it through to adulthood.  This results in a lot of wear and tear on the body, but seriously OP abilities.  (Ability ranking would be (pre)teen mahou < adult mahou < adult mahou who contracted as a child.)

Adult mahous are encouraged to register with their local police departments and form a sort of neighborhood watch/civilian police force tasked with dealing with magical threats.  Kid mahous deal with kid threats naturally, but adults come in for the nasty shit or in case a kid mahou's enemy gets out of hand.  (Rare, but it happens.)

There's no real overarching plot with this, just bits of slice of life stuff and small arcs.
