In this world, you are a catboy/girl who is constantly chasing the 6 inch mouse Niki, bearing a grudge against her, cuz she always finds a way to fool you and run away, at times making your masters disappointed by you and...

..this time, you manage to corner that little pest. Saddly, this mouse girl was not a fool, and she putted something in your food when you were sleeping. So on, as soon as you grab her, you start to "feel funny" while she burst in laugh, because in a second, you lose your grip and shrunk instantly to 1/2 inch. At this moment you are small enough to be "mouse sized" compared to her.

As you land on the ground, Niki stretches her arms and fingers, really enjoying that shocked face of yours:

Well, well, well... What's wrong, little kitten~? Not going to catch me now? Haha...
