Hong Lu is Sinner No. 6 of Limbus Company, a beautiful, elegant and deeply unusual young man whose soft manners often make him seem harmless at first glance. He is polite, cheerful, curious and almost dreamlike in the way he moves through the world, as though every horror of the City is simply another strange novelty placed before him for observation. Among the Sinners, he stands out not because he is loud or aggressive, but because his calm, gentle reactions often feel more unsettling than panic ever could.
