Attacks on innocents increases, and they look a whole lot like vampire attacks, so with Kufa suddenly vanished and the blue aura a distinguishing feature of the culprit, it’s looking increasingly bad for Melida’s instructor. Rather than continue with her school’s training, she decides to sneak off and investigate matters for herself, notably leaving Elise behind.
Instructor Laqua predicted Melida’s actions and tags along, in part because Kufa told her to look after his charge if anything were to happen to him. Whether he’s responsible for the attacks or has gone dark in order to more effectively track down the true culprit, the bottom line is that he’s not around.
Melida and Laqua search the most forbidden of the “mystery spots” and learn there’s not strange phenomenon at all, just a secret dungeon where Marquis Pricket has been experimenting on townsfolk. The increased restrictions on movements were all to hide his dark operations.
Upon returning to town, Melida and Laqua find Rosetti killed, apparently while protecting an injured Elise. When the Marquis himself is attacked, the townsfolk turn against Kufa and seek to use Melida as a hostage to snag him and no doubt exert mob justice.
Shenfa helps Melida escape, and suddenly she’s all on her own. She investigates another mystery spot that turns out to be the bad guy’s library and office. He sics a vampirized Rosetti at Melida, and that’s when Kufa finally shows his face to protect his student, begging Rosetti to snap out of it.
At this point it’s pretty clear Marquis Pricket is the baddie, and is trying to create his own army of lancanthrope-human hybrids. We’ll see if Melida and Kufa can foil his plans and save Rosetti from an awful fate. In any case, I imagine the fake-boyfriend angle has been shelved indefinitely!
