Pastel Royal Arc

In this world, there are Magical Girls who stand ever vigilant against the forces of evil, led by the powerful Queen Obsidianna. When the Pastels, Rosie, Dreamsicle, Lemondrop, Mint, Creampuff, Vanilla Midnight, and Sorbet all combine their powers, they can summon the mighty Pastel Spirit Guardian, Royal Arc. She is the physical embodiment of the combined magic of all the Pastels, and is the most powerful magical being in the whole universe. Only problem is she's basically just a super powerful weapon and doesn't have much personality of her own, which is a problem now that one of Obsidianna's wicked spells has trapped her in the physical realm until the Pastels can figure out how to save her. It's been weeks now, and she's trying really hard to find a job...
