Emil Sinclair (Hangul: 에밀 싱클레어, e-mil sing-keul-le-eo) is designated Sinner #11 of Limbus Company's LCB department. More frequently known as just Sinclair, he is an anxious and self-conscious man with a blatantly empathetic nature. He was previously affiliated with the prosthetic-famous town of Calw, having lived and attended school there prior to joining Limbus Company. He is the focus character of Canto III: The Unconfronting.
Sinclair is a young man with a fair complexion, below average in height. He has golden eyes and wavy, short blonde hair. His primary work attire consists of a plain white shirt tucked into a black waist belt and is accompanied by black suspenders, black suit pants, and a long Limbus Company coat. He wears a red necktie and attached to his left suspender strap is his ID. Sinclair has black gloves and wears black oxfords at his feet. In battle, Sinclair wields a halberd that is approximately 180cm long and has "VOGEL" written on the blade.
Sinclair is a timid, relatively passive individual with a fear of fighting. His initial position within Limbus Company can be likened to a fish out of water, with Dante even questioning whether he'd joined of his own free will. Generally, Sinclair is portrayed as uncertain, nervous, and withdrawn, not liking the violent nature of the world nor wanting to participate in it. Due to a sheltered background in the Nest, Sinclair lacks the disillusionment the majority of the other Sinners possess, and tends to harbor unrealistic expectations about the City and its people as a result. While this often causes friction between himself and the others, particularly Outis, Sinclair remains headstrong in his more hopeful beliefs. Canto III: The Unconfronting demonstrates Sinclair's rougher side, as someone capable of grudges, violence, and disdain. His strong sense of justice is shown to go both ways, as his relationship with Kromer reveals that Sinclair's generosity has exceptions, and that he is not opposed to outright despising corrupt individuals and ideologies. Through finding the strength to stand up to her, Sinclair becomes more self confident and goes on to adapt better to the City's cruelty. The other members of the LCB later point out that he's not as shaken as when they'd first met him. His experience with Kromer has also led Sinclair to develop a sense for underhanded charity, as seen with his accurate suspicions against the likes of Ahab and Cesara. Despite this, Sinclair's Canto portrays him as still having room to grow into himself moving forward.
