From the Game's Introduction:
Every saga has a beginning, they say. And so the story will often start with tales of our stalwart hero as a youth, doing appropriately scaled feats of derring-do.
But what about the other side? Weren't the bad guys ever kids too? Didn't they have the same hopes and fears, same teenage angst and ambition, same struggles to make it through the high school day?
And thus the premise of this game: What if monsters went to high school?
