Sealed inside

Soo~ Blue Exorcist. Neither Rin nor Yukio (that's normal) have any demonic powers as they aren't sons of the demonic god. What no one could've expected was however, when during their birth Satan disappeared from Gehenna. The Baal were the only ones to know about this and are keeping it a secret that their father, Lord Satan, had seemingly disappeared from Gehenna altogether. Meanwhile Rin and Yukio grew up like in Cannon since Rin still had a worrisome personality and Shiro just wanted to be sure by training Yukio. They were still boys he regarded as close to him as sons so precautions were only to be expected. However, it wasn't Shiro who always kept a look out for the older Okumura, it was someone else. Did Rin have a stalker?

"If so I'm an unvoluntary one"

It was Satan who was somehow trapped inside the inner consciousness of Rin, tied up in a normal chair and experiencing life alongside the reckless boy. It was strange, when the incident with Shiratori came, Satan could instantly feel Astaroth's aura coming from the mortal. 'His host?' questioned Satan but he almost flipped his top when -possessed nonetheless- they threatened to burn Rin's eyes out. 'The fuck is wrong with him!!?' thought the demonic god horrified if confused, he had never been on the receiving end of such actions after all.

Sadly, Rin did get a burn mark on his face, his forehead to be more precise, before Shiro appeared to stop any further damage. Satan wanted to scoff - wait what's holding him back? - at the shorthanded explanation the boy was given but became interested in the sword Rin was later given. It was for strong firedemons after all, maybe the strongest vessel he had seen for them so far.

To lock the boy in the cellar later however was a foolish decision as he tried everything to get out.
'Let me out! I need to help!' Rin thought desperately. Satan also wanted to see what's going on outside so he tried to channel some of his power into the boy's body — Rin crashed through the wooden flap.

The monastery was already heavily destroyed and Shiro had an iron bar struck through his chest. Not even thinking properly Rin ran toward him stumbling left and right at all the blood he saw, Astaroth and the demons had apparently already left to Satan's observations. (Me: you sulking or what? Satan: No, but where did you come from you dumb insect? Me: *offended and goes sulking* Just from my bed..)

Thankfully Shiro survived through surgery interference but is hospitalized until further notice. Because of that, another member of the Gehennian family takes the stage as the teenagers guardian: the one and only Samael~!
The most disliked demon king there was.

*When Satan saw him, he wanted to turn his head and bang it against a wall if he wasn't tied to a certain blasted chair!* 'Why must I now be subjected to him of all things!' he grumbled with his nostrils literally flaring.
This mortals life won't be an easy one that's on period.
And he had to watch it, great. (note the heavy sarcasm!!).

And then, as expected (for Satan at least) Rin's day-to-day life turned into a Rollercoaster.
During their time at True cross however, Satan tried to call out to Rin and contact one of his son's - hopefully Lucifer, Azazel or Egyn - and find a way to get him out. He didn't want to be in Assiah only to be trapped and not do anything by himself!

During the test of the exwires however, Satan facepalmed when Rin's bravado got the better of him and he rushed out of the room drawing one of the demon's with him.
Why did it feel like he had to be a father again!?
'To a puny mortal no less!'

When Rin drew the sword nothing really happened but he still kept trying to slay the demon (cue Satan rolling his eyes and draping a hand over his head from the display –wait how come he could move his hand?) to save himself and their group. Nothing seemed to injure the demon as much as Rin desired...until Satan decided it was time for a little experiment.
