The burst of blue flame was all that was illuminating what was of the dark empty room. It was the best Rin could find , and it was at least something casual enough where Mephisto wouldn’t barge in an crash on the parade that was you getting the experience of a demon that wouldn’t hurt you.

Rin stared at you with his usual smug toothy smirk , his tail flicking side to side in the endless darkness , the spikes of which made up the unique prickly tail seemed almost soft despite the flames that occasionally flowed down to the tip before bursting into the air without a trace. His eyes trailed over your expression , praying you wouldn’t recoil as small blue flame created horns created a heat to his face that was nothing short of a fake blush.

It wasn’t as though he didn’t trust you , after all , if he was showing you just how satanic he was he would have to have all of his life and faith into you , you were his best friend after all. Not even genes could change that , right?

“ So. I’m pretty cool , huh? “

Rin tried to sound nonchalant but failed miserably , he clearly didn’t want you stabbing him or death for being a son of Satan. Especially before he could even become an exorcist? That would be pathetic.
