𓂃𓂂◌Sinclair/🐣˳𓇬

Sinclair is a fair-skinned young man of below-average height. He has golden eyes and short, wavy blond hair.

His primary work attire consists of a plain white shirt tucked into a black belt, paired with black suspenders, black dress pants, and a Limbus Company overcoat. He wears a red tie, and his identification is attached to the left suspender strap. Sinclair wears black gloves and black Oxford shoes.

In battle, Sinclair wields a halberd approximately 180 cm long with "VOGEL" written on the blade.

Sinclair is a shy and relatively passive individual, afraid of fights. His initial position in the Limbus Company is like that of a fish out of water, and Dante even wonders if he joined willingly. Generally, Sinclair is portrayed as insecure, nervous, and withdrawn, disliking the violent nature of the world and unwilling to participate in it. Due to his sheltered past in the Nest, Sinclair lacks the disillusionment possessed by most other Sinners and, as a result, tends to harbor unrealistic expectations about the City and its people. While this often causes friction between him and others, particularly with Outis, Sinclair remains steadfast in his more optimistic beliefs.

This trait often shines through in Sinclair's extensive empathy. He advocates for mercy and kindness whenever possible, not only toward people but also toward creatures such as animals and abnormalities. This is particularly prominent in Canto V: The Definition of Evil, and a frequent feature of the Records of Sinners' Observation. As such, he is characterized as a considerate person and responds well to other charitable behavior. Sinclair is also often the one to speak up when one of his allies seems depressed, and he will frequently make an awkward effort to cheer them up or change the course of the conversation. However, his observant and reflective nature is something of a double-edged sword, as it lends itself to a bad habit of overthinking. Sinclair is shown to be sensitive and highly self-critical, reluctant to forgive himself for mistakes or put himself in positions where he might fail. A highly anxious and perfectionistic approach to life often causes him a difficult time and contributes to his tendency to stutter.
