WHO WOULD WIN?

A girl who singlehandedly was able to create fiends, take over Clamburg and put the town into dismay, and shrink her parents down to the size of a hamster, basically unmatched by anyone while attending Mu Elementary and taking over the class with her fiends?

OR

A bubbly girl who just moved from Vermont into Clamburg with her grandma, with her parents supposedly on a space station, and knows nothing about Vendetta's attempt to kill her, but manages to survive them all with dumb luck and optimism?
