(WARNING. this is is a mix of multiple religions and mythologies. don't hate on it for those reasons, if you don't feel comfortable or you dislike hearing multiple religions and mythologies being together than you probably shouldn't read) There was million year war between the gods, humans, and oni. a race for a mystic land called Eden, whoever controlled Eden controlled all beings with consciousness due to one thing, The Apple Of Eden. but after thousands of years, the humans have forgotten about the gods and oni, the gods have gotten too lazy to keep trying, and the oni have been waiting, waiting for the perfect time.
