Hey guys I'm new in this fandom and first of all this idea came from My Tamer, Your demon by Derpsassin and it seems that it was nearly a year since his last update and it was an author's note *poopie, sad face*, I really like his Idea so I hope that this is okay…

Disclaimer I do NOT own Blue exorcist / Ao no Exorcist

Prologue:

Monastery 8:00 pm

The demon named Astaroth started pursuing Rin claiming to be one of the princes of gehenna, saying that he will lead the way to Gehenna and meet his "father". The said demon wouldn't take no for an answer and continued his way through the monastery.

The truth had been unfolded to him that he was indeed a demon and not just an ordinary one, he was Satan's kin.

Astaroth breached the monastery and Shiro, his father handed him a sword and a phone saying that he should ran away as far as he could and call the only number registered on the phone, of course he didn't listen to his father about running away while the others were literally using themselves as decoys in order for him to run. All of his friends from the church knew what's going on and he was the only one who didn't know any of this shit.

The scene in front of him become fast and Astaroth has been finally exorcised. Rin was horrified, furious, shivering, and confused as he saw the damage and injury they had taken. He wanted to be mad at his father for keeping this to him. They argue and Shiro answered some of his questions and Rin didn't like the fact that he was a demon.

"Don't ever again call yourself my father! "

shiro's will falter, he didn't want to hide Rin's true self but it was for the best. Not even a minute passed his chest tighten the lights busted on their own, a frightening laugh occupied the monastery, it wasn't Shiro anymore someone possessed him, it was Satan himself.

"At last "

Rin watched his father, Satan took over control of his body and he quickly grabbed Rin's hand

"Hello my dear son" he said tracing a finger on Rin's face.

"I made an adorable one, you resemble your mother a lot" Satan said as he licked Rin's ear and breathe on his neck.

Rin wanted to scream but it felt like someone was choking him, tears fell down on him as he eyed his friends, he could see the terror they had on their eyes. He started to struggle on Satan's grip he tried to grab his sword but Satan overseen this, his grip tighten it was close to crush his bones

" Now be a good son or something ugly might happen on those guys, you didn't want to see them burnin ne? " Satan said chuckling, he snapped his fingers and strange things appeared on the floor, a gate opened, it looked like it was made from human flesh and blood, faces emerge from the floor

Satan punched Rin in the stomach making him felt dizzy and grabbed Rin's sword, making his way back to Gehenna he eyed the people inside the church

"tell his twin that daddy will find him too" he said as the gate closed leaving shiro's body, the others rushed to the fallen exorcist and found him barely breathing.
