Opalescent
by PresidentGuppy
"...alright, what is it?" Mephisto sighs, closing the window and drawing the curtains. He didn't need anyone to see him accommodating other demons--especially ones that broke through the outer barriers as if they were paper. "Well," Amaimon begins, feeling smug, "I have initiated a courtship. With Rin."

Blue Exorcist
Father Material
by Animegirl257
Satan has never tried to grow or nurture anything in his life before, but for the sake of the only person who was ever precious to him, he's willing to try just once. In a bold move that no one could have predicted, Satan possesses the body of a stillborn Rin and does his very best to raise Yukio. He's actually quite good at it, demonic tendencies and hyper-possessiveness aside. Or in which Satan is #2 dad and ends up unintentionally turning the entire world on its head. EDIT: Revisions have begun as of 1/1/2026. Re: Chapters have been revised, NEW chapters, are new.

Blue Exorcist
through rose colored glasses
by SidewaysClarinet
By some miracle, Shiro wakes up after being possessed by Satan and finds himself alive- sore, missing a few fingers, but alive. The only one who knows what happened that night is Rin himself, and he wants to take Rin's word for it when his son says that Satan abandoned his body to save it for later. However, the threads of Rin's tale are quickly unraveling, and people are becoming more suspicious. There's something not making sense about Shiro's survival, about the Kurikara, the truth of the night he was possessed. The forces of Gehenna and Assiah alike are demanding answers, and when their damning fingers turn to Rin himself, the lies begin falling apart to reveal something far darker underneath.
