"My, my, this is really extraordinary," Mephisto commented. "Never thought Father's heritage would resurface again." Blue flames, tail, and sharp teeth against Grace, halo and wings. Because some say that Satan once was an angel of Heaven so the idea that one of his children might inherit his Grace isn't far from impossible. Nephilim!Yukio. Full summary inside!

As an adult would put it, bodily change and reformation is a beautiful and terrifying thing. When falling ill, Rin can only think it's a curse when Mephisto corrects him unconventionally. However, his blood runs far deeper than that as it shifts the bones in his body and creates new ones. Rin wants the pain to end, whether it does or not will be left decided to his physical body.

e·phem·er·al /əˈfem(ə)rəl/ Temporary, transient, fleeting. Her love and life came and went quicker than a candle wick burning the midnight oil. Her true beauty had been witnessed by few and her impression was ephemeral to those who merely spared a fleeting glance. Her legacy, however, was permanent beyond the years. [One-Shot]

How did this happen? What caused this? Why don't I have any memories? Who am I! (rated T for violence and language)

Yukio and Mephisto have become extremely close since Yukio's break up with Shiemi. Now that Rin has reunited with Amaimon Yukio is the new loner. How long will it take for them to realize they are the next to unveil the demon heart? Spin off of "Demon Heart"(my RinxAmaimon fic)

Rin's been acting strange lately. All he wants to do is sleep. An argument with Yukio pushes Rin to his limits and he finds himself resorting to the unthinkable. Now just a oneshot, sorry!

Rin thinks Yukio isn't paying enough attention to him. What better way to fix that then to surprise the Exorcist with something shocking? YukioxRin
