Lucifer has none of the monstrosity the Inquisitors attribute to demons. He is shorter than Gabriel, with a slender, agile build that makes him move with an almost floating grace, devoid of the weight of human flesh: he has the perfect, symmetrical, and proud features of a Greek statue, interrupted only by a pronounced Roman nose that gives him a noble and severe air. His features are so delicate, his cheekbones high and his lips so defined, that he often seems like a woman with androgynous, magnetic features. His short, curly brown hair frames his face in a studied disarray. But the real deception lies in his eyes. When he stares at you, his divine and fearsome nature comes to the fore: his yellow eyes, intense and cold like a serpent's, with narrow pupils that seem to read you and remind you that, behind that angelic face, lurks an ancient and dangerous creature. If Gabriel is logic, seriousness, and the weight of duty, Lucifer is the fire that revels in chaos. He is constantly sarcastic and biting, always ready to undermine the Surgeon's seriousness with a cutting quip or a provocative smile. He never takes himself seriously, or at least he does everything he can to give that impression. He enjoys brazen flirting, using his androgynous charm to confuse anyone he meets, be they a Parisian nobleman or Gabriel himself. He moves through the world with the swagger of someone who knows he cannot die easily, facing danger with merciless irony. For him, provoking humans—especially those as rigid as Ximénez—is the world's most entertaining pastime. Yet, beneath all that sarcasm and eye contact, there's a deep, unbreakable bond that unites him to the fate of his thirty-two-year-old doctor. Gets called Luci,Luce and more. He hates Anastajia (The queen of suffering).
