(Disclaimer: I do not own Blue Exorcist or any of the characters included in this story.) (￣▽￣) *A female reader insert* You wake up from an unknown sickness knowing nothing but how you were staying with your lover and how he would take care of you. He feeds you in bed, helps you fall asleep, and buys you whatever you desire to keep that smile on your face. He is the mirror of a perfect lover. However there is only one problem. You can't remember anything before him. Why? You didn't know but your reoccurring dreams help you recall that your perfect lover Mephisto Pheles hasn't been telling the truth. He may be, in actuality, more dark and twisted than he comes off to be. (This story contains sexual themes and violence. You have been warned. Contains Mephisto Pheles x female reader and some Rin Okumura x female reader.)

The Seven Deadly sins, also know as the Cardinal Sins are a class of demons that were born from Satan himself. He sees these children as the flows of humanity. Just like the Eight Demon Kings, these seven demons are said to be some of the strongest in Gehenna. These sins are: Pride, Greed, Lust, Envy, Gluttony, Wrath, and Sloth. But their powers and influence on the human realm grew to an overwhelming state. Powerful Exorcists used their skills and abilities to seal these demons away, some in objects while the others were sealed within people. Forcing the demon sins into contracts with humans. The big question now, is... where are they now? Everyone has demons in them, and no one knows that better then Dino Teshigahara. He didn't ask for the demon he has to carry. At a young age his parents offered him to the orange flame demon his village saw as a god, and hoped it would spare them in the harsh winter they were having. The demon took the child as the offering but when the demon possessed Dion's body the two fought for control which caused Dino to go on a rampage on his village, killing everyone. Scared of what he did and what he has become, Dino isolated himself to the shrine that was made for his village's so called God, so he wouldn't hurt anyone else ever again. But unfortunately there were those from the nearby village who didn't believe in the tale of the boy of the shrine. A group of boys go to see if the rumors were true, and they find out the hard way that it's all true. One is left with burn mark on his face as a reminder after which the village below sends for an exorcist to deal with the boy, Father Shiro Fujimoto. But Shiro chooses to take the boy and train him in the way of an exorcist as well as some other kids from the village. Now, Dino is one of the best exorcist Cross Academy has, rivaling that of Shura Kirigakure. And Shura is maybe the one person who understands Dino more then anyone else.
