Even after Camio reveals himself, William remains concerned only with his grades and tuition and tries to distance himself from the demons and their political war.  Unfortunately, he soon finds himself roped into another problem when the Headmaster asks him to find the source of a mysterious singing voice that's been disturbing students late at night.
You stink and you're loud! 
I can't sleep like this!
¡Roncas y apestas, así no puedo dormir!
¡Roncas y apestas, así no hay quien duerma!
Você fede e faz barulho! 
Não dá para dormir assim!
