A world ruled by two kinds of... creatures? Humans and immortals. What do you mean by rule? Well, there's some sort of mist that splits our dear planet Earth in half. Half ruled by humans, the other by immortals. Fortunately, the mist lifts every 80 years that goes for 3 years! Unfortunately, a world can never fit 2 rulers. Well, war. "Kay?" "Who the hell are you and how did you know my name?!!" "Oh, so you are Kay then. Nice to meet you! My name is Zinv H-" "Answer Me Question!" "I heard some random woman called out your name and then you go crying, in my dream." "..." "Haha, just kidding! I just guessed it!" "..." "By the way, it's 'my' not 'me'. Have you not been to school?" "..." Humans in immortal society, immortals in human society. With all the governments and royalties trying to eliminate their enemies in the war. Experiments and sacrifices as well as unknown mysteries to be solved... Sigh.
