So, what's actually going on here... This is a lore animation. Meet Sima Luster, a sheep cop. She became obsessed with Merik when she saw his eyes and started spinning conspiracy theories about demons and creatures wanting to take over the world (which, of course, were just her paranoid theories). She began losing her mind over this delusion and stalked Merik to dig up more information. In reality, no demons existed at all, holy crap. The lore is massive, and I'm still dreaming of sharing more of it..
