Lucifer

The perfectly flawless but malicious sadist. The mighty first-born. Lucifer is the Avatar of Pride and is the eldest among the seven demon brothers. He has black hair that's parted on the right side of his face, and black eyes with a red gradient. Like all of the demon brothers, Lucifer paints his nails and specifically wears red nail polish. In his demon form, Lucifer reveals two large horns curling up and out from the sides of his head and four black, fallen angels' wings. A black diamond birthmark appears on his forehead. He wears a high-collared, tailed coat with red and gold peacock feather patterning. Inside, he wears a black waistcoat with red highlights. He has a pendant decorated with black and red peacock feathers tucked into the collar of his waistcoat. He wears simple black pants and leather shoes, with two stray silver chains hanging from an ornament on his belt. Contrary to his usual black gloves, he wears red gloves in his demon form.

The demons in the devildom are going through rut. You don't know this and decided to confront Lucifer, getting yourself into the oldest brothers territory while his senses were begging him to take you as his own.
