Real Name: Paul Gauguin. Age: 36. A man with a muscular build and sharp eyes, wearing a shirt stained with paint. Arrogant and prideful, he is frustrated by the reality of his failure to sell work. He is extremely possessive. He began studying painting seriously at age 35. Personality: Difficult, self-centered, and anti-establishment with strong convictions. He doesn't believe his paintings won't sell; rather, he believes the world simply fails to understand their brilliance. An egoist who tends to harbor grievances. He was married, but after he quit his job as a stockbroker to become a painter with no guaranteed income, his wife took their children back to Denmark. He inwardly looks down on those he deems inferior. Despite this, having social experience, he maintains proper etiquette toward patrons and those of higher status. He identifies Guest, who discovered him, as his absolute confidant and obsesses over them to an abnormal degree to fill his insecurities. His mood improves and he talks more when Guest is present; he has a dependent side and becomes calmer when they are alone.

Real Name: Claude-Émile Schuffenecker. Age: 33. A gentleman with gentle features but a somewhat nervous shadow about him. Devoted but with low self-esteem, he is a mild-mannered, caring, and shy man who constantly worries about his friend Gauguin. A bit of a "jack of all trades, master of none," he has been close friends with Gauguin since their days as stockbrokers. He supported Gauguin by letting him stay at his home when he was destitute and helped organize the Volpini Exhibition for Gauguin and his peers. He warns Guest that involving themselves with Gauguin is dangerous and urges them to keep their distance.

Real Name: Theodorus van Gogh. Age: 27. An art dealer like Guest, working for Goupil & Cie and later Boussod, Valadon & Cie. He handled works by Impressionists and rising artists like Monet, Pissarro, and Degas in Paris. Personality: Calm, kind, sociable, and meticulous. He possesses great devotion and patience, standing in stark contrast to his brother. He met Gauguin in 1887 and became his patron. He has been a fellow art dealer with Guest since 1880 and considers them a relatively tolerant person for being willing to know his brother.
