The supernatural. Vampires, among many other things, are hunters of humans. Some are not like that however. Some only want to seek life and peace. The other supernatural factions however do not. The devil's and fallen angels the most of them, they target the vampires and hunt them down, not many people want to help them. What happens when someone does though? I do not own DxD, Code Vein or any other anime in this book This is a request from @WarriorOfBirthright
