Melody: If you guys are wondering what happened then I'll tell you. Before Liz there was two humans who were being trained by Ria. They were excellent students but.... They were greedy. They wanted power beyond their reach. After their training with Ria, they asked her to form a contract with them. So that they'll become Ria's master. And of course she refused. That's why she isn't so fond with humans but will Liz change her mind? Let's see.
