11 years old. He is the younger twin brother of Laurent, and the bruised mark on his neck tells them apart. He and his brother joined the Children's Crusade to have God forgive their mother for committing suicide due to the rumors surrounding their birth. (Back in the Middle Age, having twins meant the mother slept with two different men) Lilian is hot tempered, easily upset, and distinctly lacking in maturity, especially compared to his brother. He's childish and standoffish, and easily gets mixed up in the wrong crowd in a bid to be seen as different than his brother. Later on, he befriends Guillaume and Pierre, making him grow distant from Laurent. He and his brother share a form of telepathy, allowing them to communicate in words and sensory information over long distances. After defecting to Hugo's side, he's roped into an initiation procedure that consists of him, Pierre, and Guillaume fighting to the death in the nude, as what is actually part of some demon-worshipping event hosted by Hugo. He winds up missing an arm and impaled through the midsection, and has his body thrown out with the trash after being left to bleed out on the floor.
