Pierce has tan skin, dark brown hair in a low ponytail, blue eyes, and horns that grow from the sides of his head and curve upwards. They are ombre from dark blue to light blue.
Pierce wears black skin tight armor, along with a robe that is light blue with black and white details. He also has a light periwinkle belt. On his right arm, Pierce has a tattoo that spans his entire shoulder and steel armor on his forearm. His left arm is covered by one of his sleeves, with a navy-colored pauldron. He wears a dark blue bracelet on his left wrist. He often carries a light blue claymore sword that has a dark blue handle.
His human disguise consists of a black tank top with belt like straps on the shoulders, black pants, and black shoes.

Daemos are the species of several characters in My Inner Demons. They come from a dark realm of floating islands of the same name. They look like humans, but they have horns, sharper teeth, pointy ears, and indigo colored blood.
Daemos naturally possess a variety of magical abilities - powered at the cost of human souls. Asch possesses fire magic, Noi possesses healing, Leif possesses both teleportation and healing, Rhys can create pocket rooms, Bish possesses ice magic, and so on. All Daemos seem to have the ability to hide their own and each other's horns and appear human-like, as long as they have the magic to do so. Daemos raised in their realm are used to the medieval-like survival of the fittest state of their world, and their instincts seem to be to fight and kill anything they come across.
Some Daemos, like Leif formerly, live in clans. Most others live under the monarchy of Prince Asch's father.
Some Daemos are in the possession of spirits, which are catlike entities that can take on a more humanlike form. As of now, they seem to be exclusive to the royal family, but that might not be the case.
