A Toy for Anger
In a world ruled by demons, where every human is a sinner, Madame Dorothy's Toy Shop is the closest to Paradise anyone will ever get.
Behind those gorgeous red doors hides a magical world engulfed in Light - which can only be appreciated by the few who can afford their entrance to her house - where's this special place, where only the most precious toys are kept.
Usually called 'the wingless angels', the Heavenly Toys are the purest among all others. They're sensitive and easily breakable.
Levitation (Levi) Döhren is one of those toys. The type that was created to be showed by his future buyer like a trophy. He was taught how to sing, draw, dance, and even speak in almost any language, for as long as necessary - hours, days. He can even stay awake for a week without rest if that's what's asked of him.
But what Döhren's training never taught him was how to survive such an unstable owner. He wasn't taught how to survive Abe Knight.
Even before Hell rose to the realm of the living Abaddon was already feared by even the strongest demons. And now that he's trapped in the human world, bored and dealing with a short supply of food he is pretty much living up to his name; The Destroyer.
He's the former guardian of the Abyss. Lucifer's favorite brother, and also his personal guard. But this new reality in which humans and demons have to coexist changed him. Even though he was always short tempered, Abaddon is losing control.
His hunger is driving him insane.
[This is probably the most difficult idea I've ever came up with... and I was kinda angry when this plot sparkled in my mind. So, whoever you are, and if you're reading this, bear with me.]
