Abyss wears a white wooden mask, then revealing a young man with long, light blue hair, tied back into a ponytail. He has jagged magic marks on each of his cheeks. His left eye has red sclerae, yellow irises and black pentagram design with black pupils. As a result of his past, Abyss is pessimistic, and desires to be useful. Despite his appearance, he is extremely shy when speaking to girls resulting in him stammering. He also fiercely loyal to Abel as one of the very few to accept him.
