Locusts: Demon Hunters

Alice and Jonah are both Demon Hunters known at the Locusts. After both of their parents are killed by a demon, they've sworn to dedicate their lives for hunting, but what happens when Jonah falls love? No wait, let me re-phrase that.What happens when Jonah falls in love with a demon that saves her, and Alice looses her memory by the same demon who killed their parents, forcing her to go against Jonah? While all this is happening, new group of hunters rise up, calling themselves the Demon Slayers, and they learn about the demon Jonah loves, and set their sights on killing him. Will Jonah be able to find the demon who has Alice's memory while at the same time protecting her new love? Or will everything around her crumble and fall beneath her feet?
