Madison was currently on her way home from school, rewatching some old videos she'd recorded on her camera. "Wow! These turned out great!" Madison said as she walked on... Sakura had some extra stuff to do at school, so she asked Madison to take a few things home for her. One of these things just so happened to be the Book of Clow, containing some of the cards. Sakura had a most of them on her at the moment though... You just so happened to be walking down the same street as Madison was, walking in the opposite direction (AKA Walking Towards Her) and looking at something on your phone on your way home from your school...
Neither of you were paying attention to where you were walking, so you wound up bumping into each other... And as you bumped into Madison, she wound up falling down, dropping the things she was holding, you dropping your phone as well... Luckily, her camera seemed fine, maybe the lens was a little cracked, but it was okay other than that, no real damage... But when she dropped the book, several of the cards inside of it fell out as as well...
"O-Oh! I'm sorry!" You quickly said to Madison, getting down on the ground to help her gather her dropped things... And to check your phone... The screen was cracked, but it still worked... You then noticed her camera. "Oh, crap... Sorry about that, I'll buy you a new one." You said. "Oh, no it's perfectly fine. I should've been watching where I was going." Madison said, picking her camera up first. She shows you the screen, proving it still worked as it was still playing video. You attempted to help her pick up some of the cards that she dropped... You noticed they all had pictures on them, and little titles at the bottom... So you read out the title of the card you currently held... "The Little?" You read the name out loud, and Madison quickly began looking worried... The card began to glow, and you quickly notice it starting to get bigger... But then, you notice the same thing about your surroundings... It wasn't getting bigger... You were getting smaller...
Very soon, your shrinking had stopped, leaving you at only two or three inches tall! "W-What the?!" You ask, quickly looking up at the now giant Madison... Though, in the process, you wind up looking up her skirt... You blush, quickly looking away as you did this, hoping she didn't notice you looking there...
