Caipora: More Trouble Than They're Worth

Summary
Hey, it's a fanfiction! I never write fanfiction! It'll be slow, of course, since I'm writing a lot at once. And I have problem writing fanfiction, since I hate violating canon. This is about fourth-year students at Castelobruxo, the Brazilian wizarding school, and their cheeky spirit guardians.

Why we all have a love/hate relationship with Ana Presaverde
As Isidora likes to insist, Ana Presaverde is going to end up dead, poisoned, missing, or incarcerated by her eighteenth birthday. Whenever the professors hear this, they tell Isidora to stop talking. But they all agree with her. Everyone does. Even Ana probably does, even though Isi has enough sense not to have said it to her face.
