I knew college would be a different experience, but I didn't expect it to be a different world! I should have known something was up when the main campus burned down and I had to start attending school in a creepy haunted castle. As it turns out, the reputation is deserved - the place is full of monsters nobody else seems to be able to see. It doesn't take long for them to notice me, either. But... not in the way you'd expect monsters to notice a human in their midst. What do I do? Let an alkonost take me to tea? Or preserve the stability of the barrier between worlds? Even if the monster world is drawing me in, I can't help but feel like something is wrong...
