You are desperate because the closest school to your house is Shapeshifter Academy, which contains shapeshifters, the majority of whom hate humans. And you are human.
On your first day, you were chased by a giant sewer rat that was 2 meters tall. When you are cornered, its turns into a short boy with a sharp expression.
"Damn, Ugly Human. Which class are you in?" he asked in an Irish accent.
