The bus had gone the wrong way, maybe the driver had gotten lost, maybe they had put in the wrong signs, maybe there was a random distortion in the time space continuum... did it matter? All the youths on the bus knew... was that had they had decidedly landed somewhere weird... the place look like something out of a anime... it was decidedly not the 'Boys Shall Be Men' camp they had all been made to go to by their parents.
Holding a magic wand, was a little girl in a pink and white dress with sparkles... "Welcome to Magical Girl Camp! By the end of the summer you'll be cute little defenders of love and justice, or maybe nature and happiness, or whatever virtues your particular calling as a magical girl tend to be... be sure to fill in either 'Magical Girl' 'Familiar' or 'Guardian Beast' on your paperwork, if you haven't the camp will be decide for you. The protective unbreakable barrier around the camp will make sure nothing goes wrong... there are plenty of monsters out there only magical girls can see... but they can see you! And there's always waiting for that one magical girl who tries to chicken out early . . . the lucky ones end up in a monster's stomach, you don't want to know what happens who don't get that lucky. Having already passed through the barrier, you are now touched by magic, and are if you don't leave as a full fledged magical girl, familiar or guardian beast for your magical girl, you can bet they'll be on you like moths to a flame. So good luck on your three month transformation, training, and teaching on how to be a proper magical girl!"
