Some dark humor origin story for a magical girl mascot. You know how people react relatively calm to the whole, "you're a magical girl now" out of nowhere thing? Well this mascot appears and the girl realistically freaks out at this random magical being poping up next to her, causing her to stumble off a small embankment and die. Ironically she was to be the most powerful magical girl, dead from a five foot drop by the being sent to help her. And it's hilarious to imagine the cute mascot trying to hide the body.

Or maybe this is just an alternate reality. In the main one the story follows she's just knocked unconscious. She finds out why alternate reality her is dead at some point after schenanagins by the mascot to cover it up.

I think I have way too many magical girl plot lines in my head both parody and serious...
