Aka Shinema

Meet Sachiko, a young woman who isn't sure what she wants. Her vampire fianci contracts with another race of legendary beings, incubi, whom Sachiko finds to be the vilest realities alive. But she's fallen for the incubus prince, Axel Ritter. Kanariya Mamoruno, Demon King, is a callous monster who wants nothing more than to use Sachiko up and throw her corpse away. Every day, every night, new victims, new thrills await him as he ravages their bodies and souls for gratification -- their pain is his pleasure as they wail in anguish as he crudely takes women ever so strongly, many times against their will. Anybody who stands in his way is dead, for he loves spilling blood almost as much as spilling his hot semen into a woman's body. If only she knew about the true face behind the suave, sensual Mamoruno. Mamoruno wants her. Mamoruno always gets what he wants.
