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 initially shows a passive personality, he often avoids confrontations whenever possible. Similar to his literary portrayal, Sinclair shows a fear of uncertainty and is displayed as a timid character. In general, Sinclair is shown to be introverted and often has difficulty with accepting the violence and insolence of the world. He often doubts himself and externally monologues his uncertainty - occasionally reminiscing over what a certain someone would've done. Having grown up a sheltered life in District 11 and now finding himself in the company, he is still considerably innocent and naïve. Demian commented that Sinclair resembled a baby bird preparing to break out of a shell.

In Canto II, Rodion comments on how she could immediately tell Sinclair was from a rich family due to the way he "walks and talks". Prior in the chapter, Faust explains that the Mariachis were seeking "unpolished and unstable" flair, suggesting that Sinclair be the one to perform a dance on behalf of the company. When he is on stage, he continues to doubt himself. Many characters comment on how Sinclair seems to be fighting some repressed turmoil and darkness within himself, mirroring his literary source and how he is fighting to break free of a shell.

Although he wishes to be a logical person, he is openly very emotional in some situations in an effort to protect himself or do his job in the company. In Canto III, after a fight with a group of N Corp. Inquisitors, Sinclair was overtaken by his emotions and continually allowed himself to skewer the corpse of a fallen Inquisitor. Don Quixote had to step in to return him to his senses, highlighting how truly easy it is for Sinclair to lose himself in his emotions. Sinclair has shown a great reaction to Kromer due to his past with her. When overcome by emotions, he is ruthless and violent. Even Kromer comments in Canto III how his speech was unlike his past self, although this rage did not make him any stronger.
