Words cannot describe the amount of both time and effort I've put into this. I've easily worked on this for three weeks straight and have put aside all the other drawings and fanfiction I was in the process of working on...

Now to explain a little about this picture; first and most important thing that should be noted is that the bronze demon is female and the silver demon is male. They each possess shapeshifting powers that lets them look human when nessisary. Both also have the ability to actually have actual flesh bodies also which is used more commonly used by the male...

Personality wise, the bronze female is much more agressive and quick to rage than her placid silver brother. The silver demon is very calm and laid back, and prefers to avoid violence if possible. Though he's extremely protective of his sister and will immeadietly rise to defend her if she needs him. These two are very close seeing is how they are the only family that the other has...

The powers that these two have are also just as different as they are. The silver is dominantly Accuracy and Speed while the bronze has massive Attack and Defense. As mentioned earlier both creatures have the ability to become human. In human form both can utilize other shared abilities such as 'Arcane Voice' which is when either of them can control people's actions and emotions though singing. The other and far more lethal ability is 'Arcane Eye' which is the ability to see quite litterally into an opponents soul and see what hurts them the worst emotionally. From there they simply talk about whatever that subject is until the opponent mentally cracks...

They may be skeletons but that's currently a form of choice, with no flesh or organs what's the opponent gonna hit? The different colored flames are actually part of their souls that act as the paste that holds the bones together. The flames can also burn clean through anything accept the others flames. The bones are also super strong and it would take force greater than a trainwreck to even fracture them, and even then they have the ability of ultra healing, and if that's not enough if they eat either silver or bronze it increases their natural healing abilities.

The final traits are mostly their preference, those gold beams coming off of the bronze are pure Light based energy that's absorbed from the heat of the sun. The Silver feeds off of Darkness, consumating it either from the nights sky directly or from any other scorce it can find. By consumating either light or darkness it drives off a rather high degree of bloodlust, without that they would probibly cause mass hysteria and panic... this little trick was taught to them by their godfather, an extremely powerful Shinigami who acts as a counciler, supporter, and referee to these two siblings.
