Invader Nanaka

Invader Nanaka is a fanmade movie crossover between Invader Zim and Nanaka 6/17.

Summary
Zim accidentally goes through a wormhole and lands in a world that he's never been to before. While he's there, he meets a strange human girl who, at first glance, reminds him a little of Dib. However, for some reason, the girl often switches from being cold and distinct to spirited and troublemaking. How long can the poor Irken invader put up with this crazy Earthling?
