Oh my. Did you draw inspiration from the manga series Kuroshitsuji/ Black Butler? When the demon said he never thought Aaron would be the one who summoned him, it was so reminiscent of the demon Sebastian saying that to a desperate and vengeful Ciel. There are also many parallel plot devices. Wow.
In any case, another wonderful piece from a master :D
With your writing ability I really think you could expand this into a multiple-part series and truly knock our socks off! Please consider revisiting this!
