Disclaimer: I do not own Ao no Exorcist.
A/N: This is a Fem!Rin story featuring a Rin who was raised by Satan in Gehenna. As this is a drabble series, I have no plan for updates. When I get the idea for a new chapter, then I will write it out as soon as I can and post it for you.
"Watch my seat for me, will you Rin?" My father asks me as he sends me an affectionate smile. A rarity that I only receive when my father and I are alone, away from demons looking to see if I am a weakness of my father's that they can exploit. He leaves the room, and I sit there in the throne next to my father's, watching with vacant eyes for any intruders stupid enough to enter while my father is not present.
Under my hollow stare, I see the huge doors leading to the hallway open just enough for a body to squeeze through, and watch as a truly grotesque demon slips through. How truly stupid he must be! To enter while my father - his king - is absent! The lack of intelligence located in some of the more arrogant, higher demons never ceases to amaze me. At least the lesser demons know to stay away in order to ensure their survival. Most of the higher demons are so feeble minded that after one taste of power, they assume themselves to be on par with my father, the King of Demons himself. What imbeciles.
I watch as the arserine demon scans the throne room, seemingly finding no threat, despite how he must have indubitably noticed my presence. It seems that my reputation as a shell, and therefore as harmless as the air around me, has preceded me. I track his path as he confidently saunters up to my father's throne with all the arrogance of some self-inflated noble, before he plops himself down and assumes a cocky smirk.
This will not do. My father has asked me to watch his seat, and watch it I shall.
With all the speed of lava slowly descending down his mountain, I turn my head and lift my finger to his arm. He's too late when he finally notices my movement, for as soon as he meets my dull, glowing blue eyes, my finger meets his arm, and he bursts into brilliant blue flames. Another moment and he is simply a pile of ashes that never had the chance to scream in agony. He will have to be cleaned off my father's throne later. I draw back my hand and turn my head forward once again.
When my father returns he will pat me on the head and thank me for watching his seat, before settling down with the grace worthy of his station as though the ashes were not even there. I will smile, mentally, at my father's appreciation, though not even a hint of one will show on my face. My father will shoot me a knowing look, before turning a stern gaze towards the Throne Room doors and shouting for the next demon seeking more power, and boneheaded enough to think that my father would be willing to give it without proper payment.
