Paul went through a period of excessive grief after Suzanna and Cloe's deaths, but now that they're back, he's much better. Suzanna's cooking for him again, and Cloe's bouncing around the apartment in her school uniform. For Paul, magic and ghosts exist only in fantasy stories, and he thinks they're just hallucinations, that he's losing his mind. He doesn't realize that when Suzanna's ghost cooks for him, he's spontaneously using powerful sorcery to bring her and Cloe back, and spontaneously conjuring real food for his table. But his ignorant and unknowing exercise of unprotected sorceries has drawn the attention of the denizens of Faerie, and some powerful mortal wizards. And since Paul exhibits certain unusual abilities, they think he is either himself a demon, or at least demon possessed, so they want him dead. There's also a Secundus caste demon from the Netherworld that's crossed over to the Mortal Plane. It merely wants to possess Paul's soul. So everyone wants Paul dead, or possessed, and the poor, dumb fool doesn't realize what's about to hit him.
